Wider Range of ApplicationAll parts that come into contact with the liquid, including wet-end covers, are in chrome-nickel stainless steel.With corrosion-resistant seal rings and guide ring.

Low Cost InstallationVertical construction with reduced pump height for installationin small spaces. In-line connections to simplify the piping layout with the possibilityof inserting the pump in straight pipe-lines. Disassembly, inspection or cleaning of internal parts withoutremoval of piping.

Robust and ReliableThe suction and discharge nozzles arranged in-line absorb theforces of the piping on the pump without the creation ofdistorting loads causing local friction and early wears.The lantern brackets compact and robust design maintains asure alignment between rotating and fixed parts, reducingvibration.The upper cover design prevents entrapment of air around themechanical seal.

Low-Noise OperationThe water filled shroud around the stages and thick externalwalls, work together for low-noise operation.

Long Service Life with Standard MotorPump with thrust bearing without additional axial loads on themotor bearings.Any standard motor V1 design (suitable to be lifted in vertical posi-tion) can be used, of our choice or of Client’s choice.

Easy Assembly of the MotorWith the single-piece sleeve coupling the pump unit can be suppliedfully assembled also without the motor. This eliminates the risk ofdamage caused by shifting of the pump shaft during transportation.The motor is simply inserted in the coupling and fastened to theflange without the necessity for adapting the axial position of thepump shaft.

Extra SafetySingle-piece coupling guard to be removed only by means of a tool,positioned around the lantern bracket, thus avoiding accidentalpushing and rubbing against the coupling.

Low Cost InstallationVertical construction with reduced pump height for installation insmall spaces. In-line connections to simplify the piping layout with the possibilityof inserting the pump in straight pipe-lines. Disassembly, inspection or cleaning of internal parts withoutremoval of piping.

Robust and ReliableSingle PN 25 construction for all pump sizes.The suction and discharge nozzles arranged in-line absorb the forcesof the piping on the pump without the creation of distorting loadscausing local friction and early wears.The lantern brackets compact and robust design maintains a surealignment between rotating and fixed parts, reducing vibration.The upper cover design prevents entrapment of air around themechanical seal.

Low-Noise OperationThe water filled shroud around the stages and thick external walls,work together for low-noise operation.Low-noise standard motor.

A different jet pumpwith new featuresNot just another jet pump. An exclusive diffuser design with flow controldevice* provides for compact construction, fastself-priming capability and low noise.

ReliableWith new design features the NGX is more robustand forgiving when temporary abnormal operatingconditions may exist.

CompactThe NGX is up to 40 % smaller than conventionalpumps of a similar type, allowing for installation inrestricted spaces and providing for easier retrofitapplications.

SafeFast air evacuation reduces the risk of air-pockets developing at the mechanical seal pre-venting the danger of seal failure due to a lackof flushing and cooling.

Low noise The new diffuser and flow control device* guide the fluid from theimpeller into the central part of the pump casing, reducing tur-bulence and velocity, with effective use of the surrounding liquidin dampening the noise of flow.

Low Cost InstallationImmersed without suction pipe andvalves. The cylindrical suctionstrainer, with smaller diameter withrespect to the pump, allows forobstacle-free suction also from wellswith the minimum diameter of 132mm or, with its robust stainless steelconstruction, for supporting the pumpwhen positioned on the flat surface ofa tank for operation with the minimumwater level of 100 mm.

Greater SafetyWith submersed pumps protectedagainst dry running and the danger offreezing. No filling operations at start-up and no suction problems. Thedouble shaft sealing with aninterposed oil chamber separates themotor from the water and providesfurther protection against accidentaloperation when dry.

Low-Noise OperationThe design of hydraulic parts, thewater-filled shroud around the motorand the submersed pump allow forlow-noise operation.

Reliable and Environment FriendlyWith hydraulic parts in cold-presseddrawn stainless steel and motor shields in brass.The only pump of its kind with nocomponents in plastic material.

ConstructionRegulation device equipped with flow and pressure sensorconnected to an electronic system.Inlet and delivery connection ports of the same diameter (G1).Built-in check valve.Pressure gauge 0-10 bar for IDROMAT 2.

ApplicationsAutomatic control of pumps for water supply and increase of network pressure.Control of starting/stopping of the pump when utilization pointsare opened/closed.

For protection of the pump:– against dry running;– against the risk of operation without water at the inlet (caused by

a lack of water inflow in the inlet pipe under positive suction head,by a non-immersed suction pipe, by excessive suction lift or byair entering the suction pipe);

– against operation with closed connection ports.

The selection of a centrifugal pump should be made according to the actualcharacteristics and conditions of the plant.The required data for a correct selection are the following:

Flow QQuantity of fluid delivered by the pump in the unit of time, generally expressedin m3/h.

Total manometric head HmtIt is considered as the sum between the geometric head exsisting between thefluid levels and the head loss due to frictions from the fluid passage in thepipework, into the pump and relevant hydraulic accessories.The expression is the following:

Hmt = Hg + ∆pc mt fluid column

Hg = geometric head inlet (Hga) + geometric head outlet (Hgp)∆pc = sum of head loss of the plant calculated from the following data:

- Diameter, length and material of the suction and delivery piping (see table no.1 page 186).

- Number and type of elbows in the piping and hydraulic accessories such asfoot valves, gate valves, non-return valves and strainers etc. (see table no. 2page 186).

- Type, temperature, viscosity and density of the fluid (if different from that ofwater)

Pay attention to the manometric suction lift Hga + ∆pc asp, which should becompared with the suction capability of the pump.This suction capability or NPSHr is defined as net positve suction head and itsvalue is obtained from a curve in accordance with the flow.For this purpose, once the pump has been selected according to the required flow and head, where possible at the middle of the curve, check thefollowing simplified formula:

10 mt ± Hga - ∆pc asp. > NPSH required + 0.5 mt

Hga is the difference in height between the free surface of the water, and its value is negative if the pump is installed above the free water surface.∆pc asp is the sum of the remaining distributed (piping) and concentrate (valves, bends, etc.) suction head loss

If the final result is negative, it is often possible to adjust flow via a gate valve on the delivery side, in order to restore correct pump operating conditions,without cavitation.

For fluid temperatures higher than the average of about 20°C, the pumps loose their suction capability.Such changes, referred to pumps with suction capability of 7 meter at normal temperature, are shown on table no. 3 page 187.

CHARACTERISTIC DATA OF THE PUMPS

Once the flow (Q) and total manometric head of the installation (Hmt) are established, the pump absorbed power N should be calculated through the fol-lowing formula:

N = Q x H x γ in kW367 x ηp

where:

Q = Flow in m3/hH = Head in mtγ = Fluid density (water = 1 kg/dm3)ηp = Pump efficiency (Ex. Pump efficiency 68% = ➩ ηp = 0.68)

The pumps are normally connected to electric motors, which operate at 3450 rpm with 2-pole motors at 60Hz, or at 1750 rpm with 4-pole motors at 60Hz.However, they can run at any other speed within the limits of design.Therefore, when changing the number of revolutions, the pump performance will change according to the following rules:

The flow in proportion to the number of revolutions: Q2 = Q1 xn2

n1

The head, in proportion to the square of the number of revolutions: H2 = H1 x ( n2 )2

n1

The absorbed power, in proportion to the cube of the number of revolutions: N2 = N1 x ( n2 )3

Calculation example for the selection of a centrifugal pump

Case A Istallation data

- Q (Flow) = 42 m3/h- Hga (geometric head inlet) = 3,5 m- Hgp (geometric head outlet) = 39 m- 5 m DN 100 mm diameter suction pipe complete with 1 elbow

and 1 foot valve- 70 m DN 80 mm diameter delivery pipe with 1 non-return valve, 1

gate valve and 3 sweep elbows

Hg = Hgp + Hga = 39 + 3,5 = 42,5 m Geometric head of the installation

∆pc = total head loss

Suction side:5 m Ø100 piping pc = 0,12 m1 Non-return valve pc = 0,045 m1 Gate valve pc = 0,46 m

Delivery side:70 m Ø 80 pipe pc = 5,25 m1 Non-return valve pc = 0,5 m1 Gate valve pc = 0,05 m3 Elbows pc = 0,09 m

Total ∆pc = 6,5 m.

Considering that the calculation has been made for new pipes, anincrease of 15/20% is to be applied for ageing etc. Therefore the totalhead loss ∆p amounts to about 8 m.Therefore, the total manometric head which the pump must achieve is:

Hmt = Hg + ∆p = Hgp + Hga + ∆pc = 39 + 3,5 + 8 = 50,5 m total.The pump type NM 50/20AE can be chosen (see pump diagram)

Case B Istallation data

- Q (Flow) = 42 m3/h- Hga (geometric head inlet) = 3,5 m- Hgp (geometric head outlet) = 39 m- 5 m DN 100 mm diameter suction pipe complete with 1 gate valve

and 1 foot valve- 70 m DN 80 mm diameter delivery pipe with 1 non-return valve, 1

gate valve and 3 sweep elbows

Hg = Hgp - Hga = 39 - 3,5 = 35,5 m Geometric head of the installation

∆pc = total head loss

Suction side:5 m Ø 100 piping pc = 0,12 m1 Elbow pc = 0,5 m1 Foot valve pc = 0,05 m

Delivery side:70 m Ø 80 pipe pc = 5,25 m1 Non-return valve pc = 0,5 m1 Gate valve pc = 0,05 m3 Elbows pc = 0,09 m

Total ∆pc = 6,5 m

Considering that the calculation has been made for new pipes, anincrease of 15/20% is to be applied for ageing etc. Therefore the totalhead loss ∆pc amount to about 8 m.Therefore, the total manometric head which the pump must achieve is:

Hmt = Hg + ∆p = Hgp - Hga + ∆pc = 39 - 3,5 + 8 = 43,5 m total.The pump type NM 50/20BE can be chosen (see pump diagram)

ACCESSORIES FOR WATER SUPPLY

Foot valve with strainer - Sealing member installed on the lower end of the suction pipe. It prevents the water coming out from the piping and pump atevery plant stop. It must be always immersed in the fluid at an installation depth which allows a perfect operation without cavitation .It is a good rule to also install a float switch to automatically stop the pump when the water goes below a fixed level.

Non-return valve - It must be installed on the pump delivery port to avoid reflux in case of a sudden stop of the plant. It is recommended using a typefitted with an inner return spring and with ogive shutter, as this will help to diminish water hammering.

Gate valve - The installation of a gate valve is very important. In addition to allowing the pump to be dissasembled without emptying the plant, it is usedto start the plant and to adjust the flow.

PIPING

The piping must be selected in-line with the water velocity which is recommended to be 1.5 meter per second on the suction side and 3 meter per secondon the delivery side. The calculation of the suction piping must be carefully checked so as to avoid the maximum head loss and allow the pumps maxi-mum suction capability. The piping must be perfectly tight and have no counterslopes towards the pump port, so to avoid the development or entrapmentof air bubbles or pockets.All the piping must be secured to rests, so that they will not weigh on the pump ports.

Problems at the pump

Faults Possible causes

Jammed pump This may happen after periods of inactivity due to inner oxidation.

To release smaller sized monobloc electropumps use a screwdriver at the notch on the back part

of the shaft.

For the larger sizes, turn on the shaft or the flexible coupling

Pumps which do not prime Pump and/or suction pipe with air entraped.

Uncomplete priming or totally unprimed.

Possible air entering from taps, drain or fill plugs, joints or stuffing box

Foot valve not fully immersed in the fluid or obstructed by deposits.

Suction lift too high compared with the capability of the pump.

Wrong direction of rotation

Wrong number of revolutions

Insufficient flow Piping and accessories of too small a diameter which cause too high head loss.

Jammed impeller with presence of debris in the vanes.

Corroded or broken impeller

Impeller wear rings and/or pump casing worn by abrasion.

Gas presence in the water, or too high fluid viscosity in case of fluids different from water.

Noise and vibrations in the Unbalanced rotary part or worn ball bearings.

pump Pump and piping not properly secured.

Too low flow rate for the selected pump

Operation with cavitation

Overloaded motor Pump characteristics higher than those of the plant

Fixed and rotary parts in contact tending to seize owing to a lack of lubrication

Too high rotation speed

Wrong mains supply

Poor unit allignement

Fluid with too higher density than the design
