4. Repeat steps 2 - 3 to specify several alternativesystems. Swap between open windows by using theCase Manager Toolbar. The open window canbe arranged as “Layered”, “Cascaded” or “Tiled” inthe Windows menu.


Search based on slurry calculation

This function selects pumps for slurry applications. Itcalculates the reduction factors caused by the presence ofsolids for the head and flow from the pump.

Note! For homogeneous, viscous or non-settling slurries thisfunction is not an adequate tool. Also, this slurry function onlysupports the Colebrook-White method for the calculation offriction losses.

Only a small amount of input data from the consideredapplication is required to use this tool. The basic input data arethe slurry description, particle size distributions (d50 and d85),SG’s of the liquid, solids and mixture, solids concentration byweight and volume, mass fraction of particles < 75µm andparticle shape (sand or mica). These inputs are used tocalculate the intersection between the system and pumpcurves, both in terms of slurry, to give the new duty point.

1. On the main Flyps screen, select Search Tab.

2. From the Tool menu choose “Defineliquid/slurry” or click the icon.

Specify liquid


3. Select a slurry type from stored projects. Fourslurries are stored as standards; copper and ironores, mill scale and sand.

Browse liquid

4. You can define your own slurry by entering adescription, particle size distributions (d50 and d85),SG’s of the liquid, solids and mixture, solidsconcentration by weight and volume, mass fractionof particles < 75µm and particle shape (sand ormica). See “Specify liquid” overview

5. Click OK twice to return to Search.

6. In the Tool menu choose File and select Save orclick the icon. It is very important to save yournew slurry to be able to find it later under “Browse.”

7. Enter the flow and head for the specific project,select connection, installation, pump type and startsearch. (Note: If you define the piping system aswell, the slurry must be defined first.)

8. Mark one or several pumps.


Main Screen - Search

9. In the Tool menu, choose Duty analysis or clickthe icon.

Duty Analysis

The following information can be viewed:

• Slurry performance curve

• Shaft power curve for slurry and clean water


• Hydraulic efficiency for slurry and clean water

• NPSHre

• System curve

• Clean water performance curve

For more detailed information concerning duty analysis, pleaselook into the respective chapter (see“Duty Analysis” on page35).

Explanations of the input parameters in the slurrycalculation

Description = Slurry name or description.

d50=The sieve size opening for which 50% of the particles arefiner, [mm].

d85 = The sieve size opening for which 85% of the particlesare finer, [mm].

SG Liquid = Specific gravity of the liquid (water is 1).

SG Solids = Specific gravity of the Solids. The density of thesolids divided by the density of water.

SG Mixture = Specific gravity of the mixture.

Conc. by weight = Solid concentration by weight, [%].

Conc. by volume = Solid concentration by volume, [%].

Mass fraction (part. < 75µm) = The fraction of the mass ofsolids of particle size smaller than 75 µm. This is valid up to0.5. Above this, the slurry will be considered homogeneous,viscous or non-settling.

Particle shape = Sand for spherical shapes or mica for flatshapes


Search based on energyconsumptionThis function is used when the lowest total energyconsumption is the primary search criteria for a pumpingsolution. Most flow duration diagrams can be simplified andreduced to a format of max., average and min. values with veryaccurate results. This flow data is very useful when searchingfor a pump selection yielding the lowest energy consumption.It can be used to determine the optimum parallel pumpsolution. The energy consumption is based on a On-Offpumping system.


2. In the Tool menu choose Flow duration or click

the icon. A window for specifying the flowduration data appears.

3. Enter maximum(peak)-, average- and minimum flowvalues and enter the duration in percentage for eachflow respectively. Click OK. The Flow durationwindow is closed.

Pump System Analysis

OverviewFLYPS 2.1 provides a number of facilities to analyze a pumpsystem.

These tools are accessed from the Toolbar or the Menu andcan only be activated when a pump has been selected.

The system curve characteristics must be defined before ananalysis can be performed. The system curve can be defined bytwo specified duty points or by specifying a pipe system.

To fully utilize these tools, good pumping knowledge isessential.

Pipe system designThe system curve is the base for all analysis in FLYPS 2.1. Apipe system with two individual pipes (suction piping and/orstation piping) per pump and up to three common pipes (forcemains) with different dimensions and properties can bespecified. A number of user-selectable point losses can beadded to each pipe section.

Branched systems cannot be analyzed.

1. In the Tool menu, choose Pipe system design or

click the icon in the toolbar. A window for pipesystem design appears.

2. Select any of the tabs Station Piping 1, StationPiping 2 or ForceMain1 - ForceMain3.

• Liquid velocity for each pipe section (station pipingonly if the Single (pump) radio button is selected)

• If the Multi (multiple pump) radio button isselected, different values for the total losses arepresented (the flow rate in the station piping willvary depending upon the number of pumps requiredto meet the total flow).

The different values for total head can be used whensearching for multiple pump solutions when thenumber of requested pumps is unspecified.


Duty AnalysisPerformance analysis is used to study pump performancecurves and duty conditions in a single or a multiple pumpsystem.

One or several flow/head-, power-, efficiency- and NPSHcurves can be displayed for comparing pump alternatives.

Duty conditions, combined and for each individual pump, canbe studied in a system with several identical pumps. The dutypoint is based on the system curve. The data is presented inboth diagram and table format.

The graphs presenting performance curves and duty conditionscan be printed or exported to a WMF-file (Windows MetaFile)

Life cycle cost analysisThe following is an excerpt from the Guide to Life Cycle CostAnalysis for Pumping Systems developed by the HydraulicInstitute and EUROPUMP.

“Pumping systems account for nearly 20% of the world’selectrical energy demand and range from 25-50 % of theenergy usage in certain industrial plant operations. Pumpingsystems are widespread; they provide domestic services,commercial and agricultural services, infrastructure services,and industrial services for food processing, chemical,petrochemical, pharmaceutical, and mechanical industries.Although pumps are offered to markets as individualmachines, they provide a service only when operating as partof a system. The energy and materials consumed inaccomplishing this task depend on the design of the pump, thedesign of the installation, and the way the system is operated.These factors are interdependent. What’s more, they must becarefully matched to each other, and remain so throughouttheir working lives to ensure the lowest energy consumptionand cost. The initial purchase price is a small part of the LCCfor high usage pumps. Operating requirements may sometimesoverride energy cost considerations, but an optimum solutionis still possible.

A greater understanding of all the components that make upthe total cost of ownership will provide an opportunity todramatically reduce energy, operational, and maintenancecost. Excessive waste and energy usage are important factors


in global environmental pollution. Reducing energy andmaterial usage also benefits the user by reducing costs.

Life Cycle Cost (LCC) analysis is a management tool that canhelp companies minimize waste and maximize energyefficiency for many types of systems, including pumpingsystems”

Life cycle cost analysis is used when comparing life cyclecosts for different pumping solutions. Future energy costs andmiscellaneous annual costs are calculated into a capitalizedpresent day value based on the selected interest rate. Thecalculation is based on the summation of the cost elements thatmake up the LCC.

LCC = (Cic + Cin + Ce + Co + Cm + Cs + Cd + Cenv)

C = cost element

ic = initial cost, purchase price (pump, system, pipe, auxiliaryservices)

in = installation and commissioning cost (including training)

e = energy costs (predicted cost for system operation,including pump driver, controls, and any auxiliary services)

o = operation cost (labor cost of normal system supervision)

m = maintenance and repair cost (routine and predictedrepairs)

s = down time cost (loss of production)

d = decommissioning/disposal cost (including restoration ofthe local environment and disposal of auxiliary services).

env = environmental cost (contamination from pumped liquidand auxiliary equipment)

Pumping solutions selected in all open Cases can be compared

1. Select pumps by searching (See “Search” on page16)

2. Mark one or several pumps in the pump list andchoose life cycle cost in the Tool menu or click theicon in the toolbar. A window for economy analysis


appears. The marked pumps are ”transferred” intothe analysis window.

4. To include pumps selected in all open Cases, selectthe option Include all open cases. All marked pumpsin the inactive Cases are “imported” for the purposeof performing a life cycle cost analysis.

5. Select the LCC button.


1. Select the Initial Investment and DecommissioningCost tab.

2. Enter the cost of the pumps, controls, accessories,piping and engineering and design in the appropriatetext boxes. This will encompass Cic TotalEquipment Cost. The pump cost should be perpump while the balance of the items should be totalcost. Costs that are not applicable should be left as”0.00”.

3. Continue with installation cost and commissioningcost (including any training), to make up Cin.

4. Enter any decommissioning cost.

5. Select the Annual Costs tab.


1. The annual pump energy cost is calculated anddisplayed in a grayed out text box.

2. Enter any other annual energy cost for the auxiliaryequipment. This will be added to, and displayed asthe Total Energy Cost.

3. The next two text boxes are for the pump operatingcost and any additional operating costs.

5. The next two boxes are for the pump maintenancecost and any other maintenance costs.

6. These two boxes are added together and displayedas Total Cost of Maintenance.

7. Next are inputs for down time cost andenvironmental cost. These are added to the threeabove totals to give the Total Annual Cost.

8. Select OK to view the bar graphs in the LCCWindow.


VFD - AnalysisThe VFD analysis tool is used to examine the effects ofvariable speed pumping with a Variable Frequency Drive(VFD). Two ways of applying VFD controls can be analyzed:

• One-Pump, One pump is speed regulated and allothers run at full speed with On-Off control.

• All-Pumps, All pumps in the system are speedregulated in parallel.

A number of graphs can be displayed to show the effects ofVFD use in the specified system. Graphs can be printed orexported to a WMF-file (Windows Meta File)

1. Select pumps by browsing or searching (See“Browse” on page 15 or "Search" on page 16).

2. Mark one or several pumps in the pump list andchoose VFD analysis in the Tool menu or click

the icon in the toolbar. A window for VFDanalysis appears. The marked pumps are”transferred” into the analysis window.

3. Click on the pump list to select a pump.

4. Select the type of VFD control: One-pump VFDcontrol or All-pumps VFD control. The two VFDcontrol scenarios that are available are by far themost popular. The first, “One-Pump VFD” refers toa control scenario where one pump is speedregulated while all other pumps that are running areat full speed. This scheme starts with the speed-regulated pump coming on first and increasing inspeed until it reaches full speed. At this timeanother pump would be started and this pump wouldrun at full speed while the second would be speedregulated. This would continue until all pumps wererunning at full speed. The shut down sequencewould be in reverse. The second scenario, “All-Pumps VFD”, refers to a control system in which allpumps are speed regulated together. In such asystem all pumps would be run at the same time andthe same speed. They would be increased in speeduntil they all reach full speed.


5. Click the appropriate tab to display a diagram.

6. The graph shown can be printed by clicking thePrint button. The graph can also be exported to aWMF-file by clicking the Export button.

VFD Analysis - Frequency curves

Specific Energy

VFD Analysis - Specific Energy

Specific energy is defined as the energy consumed by apumping system (pumps and piping system) for a givenvolume of pumped liquid. This is a measure of the system'senergy consumption per unit liquid, and is usually expressedin kWh/Mg (kilowatt hours/million gallons). Specific energyis useful when comparing different pump and piping systemsolutions from the operating cost point of view.

The graphs show data plotted versus flow.

• One-pump VFD control, Specific Energy whenone pump is VFD controlled and the others run atfull speed On-Off controlled.

• All-pumps VFD control, Specific Energy whenall pumps in the system are operated on VFD's.

• On-Off control, Specific Energy when all pumpsrun at full speed in an On-Off controlled mode.

The following refers to the three types of VFD’s. Flyps willuse this value to determine the efficiency of the VFD and inturn calculate the specific energy.

The Ideal button selects a typical PWM VFD, but it ignoresthe effect the VFD can have on a motor related to torque. Thiseffect is taken into account in the next two types. TheFrequency ~ Voltage option is the most common PWM VFDtype. Here, the voltage remains proportional to the frequencythroughout the reduced frequency range. This means thetorque capability of the motor remains constant as frequency isreduced, but the attached (centrifugal) load will be reducedmore quickly than the linear reduction in frequency. Thus therelative load on the motor becomes less and less as frequencyis reduced, and at lower loads the motor will tend to operateless efficiently. The Frequency ~ Voltage2 is therecommended PWM VFD type for centrifugal loads. In thiscase, as frequency is reduced the voltage is reduced by thesquare of the reduction in frequency. The motor torque isreduced more quickly than in the above case, roughly in thesame proportion as the attached centrifugal load. Thus, therelative load on the motor is almost constant so it operates atabout the same high efficiency at lower loads as it did at fullload.

OverviewWe will explore, step by step, the procedures needed toperform your first pump search and basic system analysis inthis section.

This guided tour is divided into two parts.

The first part is basic and covers a pump search together with asimple system analysis and product data printout.

The second part is more advanced and covers different aspectsof pump searching together with an extensive system analysis.

It is assumed that you are comfortable with working in theWindows environment.

Basic pump search

Task descriptionFind a suitable pump for a duplex wastewater pump station.The pump should be in a wet pit installation. The design flowfor the station is 350 GPM and total head is 29 ft. Availablevoltage is 460 V with a frequency of 60 Hz.

The following parameters should be included in thespecification of the pump:

Enclose printouts of a dimensional drawing and performancecurve for the specification after retrieving all the data.

If you have studied the manual for FLYPS 2.1, try to solve thistask by yourself. Otherwise, let the following pages guide youthrough the pump selection process, and learn how to retrieveperformance and product data and how to print outlinedimensional drawings and performance curves.

SolutionPump search

The first step in a search is to enter the duty point. Enter flowand head. Static head can be set to zero if it is unknown. Theentered value in the input box is total head, i.e. the sum ofstatic head and friction loss.

The C-type impeller is typical for wastewater applications (SeeAppendix “Description of Flygt pump types” on page 88 formore information). It has a high efficiency and excellent solidshandling properties. We are searching for a wet pit pumpinstallation, so be sure that the installation type is set to wet.


The specification stated that one pump should be able tohandle the duty point. This means that the connection shouldbe set to single.

Remember to always make sure that proper search criteria areused. Incorrect search criteria may result in an incorrect pumpselection.

A search interval of ± 10 % is adequate for low flows. Forlarger flows, use a narrower interval. The min. / max. value inthe multiple pump search section is not accounted for whenrunning a search with a single connection. FM approval is notnormally needed for standard wastewater applications. For therest of the parameters, use the default values. Search for allpoles, phases and materials.

1. Select the Search tab

2. Specify duty point.

• Enter flow. 250 GPM.

• Static head is unknown. Enter 0 ft.

• Enter head. 29 ft.

3. Click to choose impeller type C.

4. Set Connection to single.

5. Set Installation to wet-CP.

6. Click the Search criteria button. A window to setSearch criteria appears

• Set Search interval. - 10% and + 10%.

• Set Approval to Standard.

• Make sure that All poles, All phases andAll materials are selected. Click OK.


1. Click the Start search button to perform a search.

After running the pump search, the pump list is displayed. Itshould look like the one below. Minor differences may benoted due to different product mixes in a later version of theprogram.


Main screen - Pump list

The pump list can be sorted according to different criteria.Sorting can be done with respect to no of pumps, deviationfrom duty point, specific energy and total energy.

The fact that we are searching for a single pump means that itis useless to sort by number of pumps. A duration diagram hasto be specified in order to sort on total energy. The relevantparameters left to sort on are deviation from duty point andspecific energy.

The following performance data can be obtained in the resultlist:

• Duty point flow

• Power consumption (input power)

• NPSH req.

The C 3102 is the least expensive one in the pump list. Let’sanalyze this pump to determine if the duty point is acceptable.Specifically, we want to determine if the duty point is withinthe preferred operational range on the pump curve, if NPSHreq. is acceptable, if the efficiency is sufficient, etc.

SolutionPipe system specification

The first step is to calculate the losses in the system. This isdone in the Design pipe system window. The pipe system isdivided into two different kinds of pipes, station piping andforce main pipe. The total flow runs through the force mainand the flow in the station piping is the flow from each pump.

You can specify one or two station pipes for each pump in thesystem and up to 3 force mains. Diameter, length, material/roughness and point losses must be specified for every pipesection.

If length is omitted for a pipe section, it will not be accountedfor in the loss calculation.

Five pipe sections are normally enough to model almost anypipe system, including complex ones.

Station piping

1. In the Tool menu, choose Design Pipe System

or click the icon in the toolbar. A window fordesigning a pipe system appears.

2. Enter flow. 2500 GPM

3. Enter static head 15 ft.

4. Select the first station piping tab.

Note. The water velocity stated in the lower left corner iscalculated for single pump duty only. When running multiplepumps, the velocity in the station pipes will decrease due tochanging duty points. The loss factors can be edited in thesetup.

Force main

1. Specify losses in the force main. Select the Forcemain 1 tab or click on the pipe section in thepicture of the pipe system.

2. Enter length. .

3. Make sure Standard pipes are selected.

4. Choose ductile iron in the Material drop down listbox

5. Choose CL53 in the Pressure class drop down listbox

6. Choose 20 in the Dimension drop down list box

7. Specify point losses. Add 3 x 90°°°° Bend and 1 xOutlet by clicking on the spin control in the editboxes.


Loss calculation. Specification of force main.

If the option multi pumps is selected, the duty points for adifferent number of pumps are shown in a list. Both head lossand total head are shown. The min. and max. values for thenumber of pumps defined in Search criteria determines thenumber of duty points shown in the list.

The loss calculation method used in this case is Hazen-Williams. Calculation methods can be changed in the Setup.For more detailed information about the calculation methodssee Appendix “Head loss calculation methods” on page 92.

8. Click OK to return to the Main window.

When back at the main window, the edit boxes for static head,total head will be filled in and disabled.

Duration diagram specification

The flow variation throughout a 24 hour period is, in this case,substantial. This implies that we have to specify a durationdiagram in order to do an accurate energy consumptioncalculation.

1. In the Tool menu choose Duty analysis or click

the icon in the toolbar. A window for specifyinga duration diagram appears.


2. Specify maximum flow (peak flow). Enter Max.flow. 2500 GPM. Enter duration. 5%.

3. Specify average flow. Enter Avg. flow. 1500 GPM.Enter duration. 60%.

4. Specify minimum flow. 550 GPM. Enter duration.35%

Graph plotting a can be switched off by clicking in the Graphcheckbox.

5. Click OK to return to the Main window.

Pump search based on a given system and with aspecified flow duration diagram

The basic details of a search were described in Tutorial 1, andwill not be discussed here.

The C-type impeller is typical for wastewater applications. Ithas a high efficiency and excellent solids handling properties.In this case, the number of pumps is not specified.

1. Make sure Calculate head based on system isselected.

2. Make sure Use duration diagram is selected.

3. Click to choose impeller type C.


4. Set Connection to Parallel.

5. Set Installation to Wet.

6. Check search criteria. To have same results as in thetutorial set search interval to -5% and +5%.

7. Click the Start search button to perform a search.A list of pump alternatives fulfilling therequirements will appear.

8. Sort the result list on total energy consumption.Click on the Total energy column heading.

Results from pump search. Sorted with respect to total energy.

The solution with the lowest specific energy at the maximumflow does not necessarily have to be the one with the lowesttotal energy consumption.

In systems with normal flow distribution and high losses,multiple pump solutions tend to have lower total energy thansolutions with few pumps. This is due to the fact that thelosses decrease when fewer pumps are running.


Duty point analysis

Always remember to check if the duty point(s) are on thepreferred part of the curve, not power limited, NPSH requiredis OK, etc. When running with multiple parallel pumps it isimportant to check all duty points.

Normally when selecting a pump, alternatives with negativedifference are discarded.

1. Select the best pump (according to total energy) inthe result list. Click on the first pump in the resultlist.

2. In the Tool menu, choose Duty analysis or click

the icon in the toolbar. A window for dutyanalysis appears.

3. Select the Duty condition Tab.

4. Check single pump duty. Decrease No. of pumpsrunning by clicking on the spin control.

Duty analysis one pump running


Summary

The objective in this tutorial was to optimize for minimumenergy consumption. By sorting the pump list with respect tospecific energy, we will find a single CP 3201 which canhandle the specified duty point. How much energy is saved byselecting the optimum 2xCP 3127 solution instead of thesingle pump solution? Total energy during 1 year for the 2pump alternative is 61,600 kwh and for the single pumpalternative 74,500 kwh. The energy saved by using 2 pumpsinstead of one is 74,500 - 61,600 = 12,900 kwh. Whether ornot these savings are justifiable can be analyzed with the Lifecycle cost tool.

Head loss calculation methodsThe loss calculations in FLYPS 2.1 are based on theassumption that the pipes are entirely filled with liquid andthat the liquid has the qualities of clean water.

Density: 62.4 lb/ft³ Kinematic viscosity: 1.2 x 10-5 ft²/s

Description of loss calculation:

Htot = Hs + Hf

Htot = Total head

Hs = Static head

Hf = Head losses

The head losses consist of two parts:

hf= hfl + hpl

where hfl = Friction losses, hpl = Point losses

In FLYPS the friction losses can be calculated with twodifferent methods:

Pump search methodologyDuring a duty point search for a pump, the program searchesfor the intersection between the system curve, which runsthrough the requested duty point, and the pump performancecurve. This intersection is the duty point for this pump curve.The distance between the requested and actual duty point iscalculated and compared with the distance to the requestedduty point (see graph below). If this relative distance fallswithin the given search interval, the curve is regarded as a hit.The search interval is given with both a positive and anegative limit. Performance curves where the requested flow isless than 15% of the curve's maximum flow are not included inthe search. This is done so that the program will not suggestpumps where the duty point would be close to the shutoffhead.

• C1 Pump curve

• C2 System curve

• P1 Requested duty point

• P2 Actual duty point (calculated intersection)

• D1 Distance to requested duty point

• D2 Distance between requested and actual dutypoint

Relative divergence between actual and requested duty pointsis calculated as follows:

Rel. div. = D2 / D1

Glossary

Cd

Decommissioning/Disposal Cost (Cd)

Decommissioning cost includes the restoration of the localenvironment and the disposal of pumps piping and auxiliaryequipment. In the vast majority of cases, the cost of disposingof a pumping system will vary little with different designs.

Cenv

Environmental Cost, Including Disposal of Parts andContamination from Pumped Liquid (Cenv)

The cost of contaminant disposal during the lifetime of thepumping system varies significantly depending on the natureof the pumped product. Certain choices can significantlyreduce the amount of contamination, but usually at anincreased investment cost.

Examples of environmental contamination can include coolingwater and packing box leakage disposal, hazardous pumpedproduct flare-off, used lubricant disposal, contaminated usedparts, such as seals. Costs for environmental inspection shouldalso be included.

Cs

Downtime and Loss of Production Cost (Cs)

The cost of unexpected downtime and lost production is a verysignificant item in the total LCC and can rival the energy costsand replacement parts costs in its impact. The value of lostproduction can dwarf all other elements. Despite the design ortarget life of a pump and its components, there will beoccasions when an unexpected failure occurs. In those cases

96 •••• Glossary User's Guide FLYPS 2.1

where the cost of lost production is unacceptably high, a sparepump may be installed in parallel to reduce the risk. If a sparepump is used, the initial cost will be greater but the cost ofunscheduled maintenance will include only the cost of therepair.

Cm

Maintenance and Repair Cost (Cm)

Obtaining optimum working life from a pump requires regularand efficient servicing. The manufacturer will advise the userabout the frequency and the extent of this routine maintenance.Its cost depends on the time and frequency of service and thecost of materials. The design can influence these costs throughthe materials of construction and components chosen and theease of access to the parts to be serviced.

Co

Operation Cost(Co)

Operation costs are labor costs related to the operation of apumping system. These vary widely depending on thecomplexity and duty of the system. For example, a hazardousduty pump may require daily checks for hazardous emissions,operational reliability, and performance within acceptedparameters. On the other hand, a fully automated non-hazardous system may require very limited supervision.Regular observation of the functioning of a pumping systemcan alert operators to potential losses in system performance.Performance indicators include changes in vibration, shockpulse signature, temperature, noise, power consumption, flowrates, and pressure.

Ce

Energy Cost (Ce)

Energy consumption is often one of the larger cost elementsand may dominate the LCC especially if pumps run more than2000 hours per year. Energy consumption is calculated firstby gathering the data on the pattern of the system output. Ifoutput is steady, or essentially so, the calculation is simple. Ifoutput varies over time, then a time-based usage pattern needsto be established.
