2 Selection of pumps and mixers

In this section you’ll see a selection of positive displacement and centrifugal pumps suitable for chemical applications as well as a series of top entry mixers.

Our stand is divided into four areas, each featuring the different parts of our broad offering.

3 APEX - latest news from Bredel

Bredel has recently released a new general purpose hose pump series the APEX. These pumps offer all the advantages of a peristaltic pump technology and are perfectly suited for abrasive, shear sensitive, corrosive, high and low viscosity liquids.

4 AxFlow Services

Consultancy, systems design, logistics, maintenance and repair – these are just examples of the services that our customers enjoy. Come and see the full service offering.

Mixing it with AxFlowFor AxFlow, with Lightnin Mixers’ brand of portable/fixed mount mixers and Plenty Side Entry mixers, the major objective has always been to offer products that match specific process requirements, reduce capital and operating costs and improve process yields.

Lightnin portable/fixed mount mixers

Lightnin portable/fixed mount mixers provided by AxFlow offer an economic solution for many

mixing applications where efficiency, performance, flexibility, ease of operation and simple maintenance are the key factors that influence selection. The three major areas that affect mixer performance are the design of the drive shaft mechanism, the impeller and the mounting arrangement. With portable/fixed mount mixers, users are looking for a low maintenance unit that can accept a range of impellers and a method of securely mounting the unit to the vessel.

With the ATEX accredited ECL mixer, sealing all the shaft bearings for life and using gears that are synthetic grease lubricated for continuous lifetime service have achieved maintenance free operation of the drive mechanism. The large output shaft bearings have been included in order to accommodate

longer shaft lengths. The other elements that contribute to an extended working life include a unique motor coupling that protects the gearing from shock torque loads and increases the life of the motor bearings.

The essential element in efficient mixing is the impeller and for each application there is a specific impeller design. The ECL mixer uses the Lightnin A310 impeller, which has been designed

specifically for low viscosity and flow-controlled applications. This axial flow design outperforms all other types of impellers in the turbulent mixing regime by generating up to 70% more flow for the same speed power. For more specialist applications, the ECL can be used with several other types of impeller, which can be specified according to the application.

For specialist duties that demand a robust and rugged design where the gearbox, shaft and impeller systems provide a long trouble-free working life. AxFlow offers the Lightnin Series 10. The strength of the Series 10 mixer lies very much in the design of the gearbox, this being a single reduction unit

containing helical gears that are case-hardened and nitrided for long life. Equipped with the largest tapered roller bearings in a mixer of this class, the Lightnin Series 10 has the ability to run for more than 100 000 hours. The efficient in-line helical gearing and parallel shaft minimise horsepower loss through the drive train, thereby ensuring that more than 95% of the power available is transferred into the mixing vessel.

Splash lubrication of all internal parts provides excellent operation without the need for pumps and piping, whilst an oil-dam ensure that oil cannot leak down the output shaft even if the output shaft lip seals fails.

Plenty Side Entry mixers

Plenty Side Entry mixers contribute to reducing the costs of mixing and blending

in large tanks and are used extensively in the oil production and BioFuels sectors. Unlike

top entry mixers where the impeller is restricted to absorbing around 85% of the power, the side entry mixer absorbs almost 100% of the power as it is not fighting against the flow regimes which can give big surges in power. With side entry impellers, there are no surges in power other than on start up.

The side entry mixer provides a physical element within the tank that forces the contents up and back down within the tank, and this performs the duties of blending, homogenising and temperature uniformity. Swivel angle mixers offer the additional benefit of cleaning the entire tank floor. This capability can be automatic to reduce the fallible human element and prevent sludge from settling all the time the mixer is operating.

Plenty Heavy Duty side entry swivel angle mixers are available from AxFlow with both manual and mechanical actuators. Setting the angle of the shaft is essential to the effective performance of the mixer and the angle does have to be adjusted at regular intervals to ensure an even contour pattern across all areas of the tank. The automatic swivel actuator can be supplied either fitted to new equipment or retrofitted to existing installations. Operating continuously when the mixer is in use, the actuator swivels the mixer unit from 30o left to 30o right and back again. The advantage of this capability is that it frees up plant operatives for other duties and ensures more efficient tank cleaning. ■

Other featured products...

Designed to suit all dosing, metering and transfer applications from 2.8-1200 l/hr flow across a

broad range of applications, the new APEX pumps are suitable for wide spectrum of industries. The absence of expensive wearing parts means that this new range of hose pumps can be used for transferring abrasive, corrosive, viscous, shear-sensitive, crystallising or even fluids presenting a combination of these properties.

Suitable for pressures up to 8 bar, together with reliable and stable flows up to 1200 l/hr (with 20mm diameter hose), the APEX is a great choice for ongoing, precise dosing. This is boosted by a new generation of long-lasting hoses that also supports repeatable accuracy when metering additives, while continuous pump speeds up to 100 rpm provide a wider capacity range in comparison with alternative hose pumps ■

The EZstrip™ is Mono’s latest pump design By simply removing a few screws, the suction chamber is easily dismantled, giving access to take out any rag build-up, a process that takes less than 2.5 minutes.

Positive displacement pumps from Waukesha Cherry-Burrell are designed for high volume, lower cost and CIP (clean in place) applications They are the leading manufacturer of component equipment for sanitary and industrial applications.

The SANDPIPER® air-operated, double diaphragm (AODD) pump range offers heavy duty ball, heavy duty flap, containment duty, and standard duty configurations. There is no other pump type on the market today that is so universally applicable and so responsive to pumping problem fluids.

AxFlow Systems - engineering capability by AxFlow AxFlow Systems provide pump users with a single point of contact for design, construction, installation, commissioning and maintenance of pump skids and packages.

These systems range from compact skid-mounted units designed to enhance dosing performance within larger production processes, through comprehensive fixed and mobile trailer-based mixing and delivery packages to complex blending and dosing systems that bring together many liquid handling technologies.

AxFlow Systems draw on AxFlow’s extensive knowledge of fluid handling technology and have the experience in identifying the critical points in a process system that influence plant performance, efficiency, use of materials and finished product quality.

“We have been offering fluid handling systems in selected EPA markets for many

years, but our new approach is to offer these systems throughout Europe. We believe the combination of knowhow in fluid dynamics, systems design and construction together with ready access to the best pump technologies in the world makes a very strong proposition to our customers” says Olga Krejci, Marketing Director, AxFlow Holding AB.

For many of AxFlow customers, it makes better business and economic sense to source full design, engineering and installation from single experienced supplier, whether it be a simple skid mounted unit or a full processing package. AxFlow Systems enables them to buy a system that has been designed and engineered specifically for the application and plant. This eliminates complex, protracted and often frustrating management tasks and once in operation there’s a clarity to the service, maintenance and responsibility that brings peace of mind. ■

Colour blending solution to USAIn 2011 AxFlow Systems received an inquiry from Glaxo Smith Kline USA for a colour blending unit.

Since 1995, four of those tailor made Colour Blending Units (CBU’s) have been in continuous use at the GSK toothpaste factory in Maidenhead England.

These units were designed, engineered, built and commissioned by AxFlow Systems. Also, the complete local control and communication with the factory SCADA (supervisory computer system) was supplied by AxFlow Systems and the maintenance of the Pulsafeeder pumps was done by AxFlow

UK. Due to this succesfull service, AxFlow UK got the possibility to deliver Waukesha pumps for transport of the toothpaste.

The units delivered form the heart of the bulk production of the biggest toothpaste factory in the world, producing the coloured and flavored stripes in the toothpaste (for example Aquafresh and Macleans). The advantage of these CBU’s is that there is very limited product loss and downtime between product change and very fast CIP with only limited cleaning fluid.

After more than 16 years of successful and stable production with limited maintenance, the production facility in New York in USA is now also ready for this change. After ¾ year of tendering and questions, AxFlow Systems secured the order early March 2012.

The system will be built and tested (FAT) in Dronten to be transported and reinstalled

in the factory in New York where it will be commissioned and retested (SAT). It will

be ready for the first production in October.■

In February 2010, AxFlow Romania’s field sales manager Catalin Rusu received an enquiry for a dosing installation from Romania’s largest refinery Petromedia in Constanca. This resulted in the refinery becoming interested in the possible supply of three skid-mounted dosing units.

At the outset, AxFlow Systems had to prequalify for the refinery. Thanks to their references and the suggestion to use Bran + Luebbe pumps and Lightnin mixers, they were accepted by the customer as a suitable vendor for the project. The first proposal was made in March and after extensive work throughout the year Catalin Rusu secured the order for nine B+L pumps and two Lightnin mixers in December 2010.

The complete delivery consisted of three stainless steel (SS) ATEX skids each with a SS 1,000lt - 2000lt tank in accordance with ASME VIII, of which two were fitted with ATEX mixers. All three skids were fitted with two B+L pumps, with one of the skids containing double headed pumps. The tanks included magnetic level gauges with a 4-20mAmp/HART output and breather/flame arrester. All interconnecting SS pipework, valves and safety relief valves were included in the delivery.

The products to be handled were anti-foaming and anti-fouling agents, together with corrosion inhibitor in pressures up to 20bar. Three pumps were also supplied for flushing water and flushing oil.

AxFlow Systems engineered, quoted and constructed all three units and tested them prior to shipment to Constanca in May 2011. Following this order, a further contract was secured in April 2011 for the supply of two SS ATEX skids for the same refinery to handle anti-foaming agent. These skids are each equipped with SS 1,000lt tanks and Lightnin mixers, plus one B+L dosing pump and an ATEX junction box. These two additional skids were delivered in October 2011.■

Dosing units for ref nery in Romania

Scanship is a leading supplier of waste and sewage management technologies to major cruise liners.

AxFlow in Norway has worked with Scanship since2002, firstly as a supplier of hose pumps to their food waste systems. In 2010, AxFlow expanded the offering with centrifugal pumps and has also delivered complete double pump units.

The latest project included centrifugal pumps for grey and black water waste management within cruise shipping. The time frame was very short and the complete system needed to be delivered within five weeks from ordering. Initially, the order only included pumps but was later extended to encompass AxFlow’s system service as well.

The waste management system on a ship is complicated. All waste must be taken care of and processed on board – often amounting to several tons each day on a cruise liner carrying up to 3,000 passengers. The biggest part of the waste is made up of grey water – waste-water from domestic activities, such as dishwashing or bathing, and black water – sewage containing human waste.

In Scanship’s waste management system, the liquid is separated and refined into a state of clean water, in

accordance with government regulations. The remaining dry solids can then be incinerated into ash. The complexity of this type of process requires a genuine understanding and expertise. In this case, especially within pipe welding.

AxFlow provided Scanship with an efficient solution combining standard pumps and partial customisation of the waste management system. AxFlow System’s proximity to Scanship’s customers proved to be a clear advantage, leading to a significantly shorter delivery time and cost-savings in transportation.

“To Scanship, having a single point of contact for their entire pump systems and logistics is a big advantage. It allows them to reduce the number of people working on an increasing number of projects. Environmentally, an effective waste management system is of utmost importance for Scanship and their customers,” says Christian Semb, Sales Manager, AxFlow, Norway. ■

Can pump maintenance contribute to lower operating costs?

Many pump manufacturers are doing their utmost to drive down energy consumption costs by offering energy efficient motors, matching impeller

diameters to actual operating conditions and recommending the use of variable speed drives. This approach is to be applauded, but if pump users do not create the best operating conditions and look after their pump systems the opportunities for reducing operating costs are compromised.

Pump systems are large consumers of electricity and their operation will always have an impact of the price of the final product or service. A pump that is matched to the application will contribute to energy savings because its performance is tailored to the needs of the system. Selecting an oversized pump in the belief that one day it will become useful if production is increased or for safety reasons is a false economy. Similarly, running a pump without any checks on component wear and maintenance will reduce operating life and increase operating costs over the medium to long term.

It is inevitable that pumps will display signs of wear, as it is almost impossible to design a pump that is free from operational deterioration. Wear will have an adverse influence on the performance of the pump, causing mechanical losses, leakage and energy (hydraulic) losses. Components most likely to be affected are bearings, mechanical seals, wear rings, rotating elements and the shaft. Then there is the matter of the internal surfaces which can be subjected to corrosion and erosion by the pumped fluid. Surface conditions will have the greatest on energy losses.

The best way of ensuring trouble free and low maintenance pump operations is to invest in careful pump selection and proper installation at the outset and then to monitor changes in performance at regular intervals. If the pump has been sized for the application, dynamically balanced, installed on robust foundations in order to avoid vibration and operated in the correct manner appropriate to the application then a major failure should never be experienced.

AxFlow Services

Against a background of rising energy prices and the greater pressures to reduce CO2 emissions, it is becoming increasingly important for all sectors of industry to consider the operating efficiency and energy consumption of pump systems.

This may add costs to the initial investment, but over the long term the investment will be paid back through energy efficiency, low downtime and reduced maintenance costs. Unfortunately not all pumps are operated to their best efficiency point or they are left to operate unattended for long periods, so when the pump does eventually crash it is either replaced or fitted with replacement parts without any investigation as the causes of the failure.

There is of course an argument that puts forward the case for restricting planned and preventative maintenance. In other words; ‘if it ain’t broke, don’t fix it’. Too much maintenance intervention can result in damage to components when they are removed and r e in s t a l l ed . This is par t icular ly apt where the mechanical seal is removed. Misalignment when the mechanical seal is being reinstalled will cause excessive movement and eventual failure of the seal’s faces.

Striking a balance between preventative and condition-based maintenance lies in careful monitoring of the pump performance, so that if any symptoms of a problem are noted action can be taken that prevents total pump failure. The pump should only be taken out of service for maintenance after a detailed study of the symptoms and causes has been carried out. If there has been physical or mechanical damage of the pump’s components, then a review of the process operation need to be undertaken in order to identify the cause of the damage.

Preventive, predictive, and prevention/pro-active maintenance practices generally require the pump operator to have an in-house team of qualified employees or to have maintenance contracts with the pump manufacturer. However, this is not always feasible and that is where outsourcing this work to a knowledgeable contractor who can work closely with the maintenance personnel on determining failure and then assist in the repairs or design changes if these are required.

When the AxFlow Service Base in Huddersfield is called in to provide both on-site or off-site maintenance and repair, it is standard procedure to examine the

pump in detail and to discuss with the customer the application and operating conditions. In this way the Company is able to provide a wholly effective solution to the problem and give a guarantee on its work. AxFlow recognises the importance of planned maintenance and offers all its customers this service, which is also supported by a 24-hour call-out service. Where feasible, remedial work is carried out at the customer’s premises and typically this will involve identifying the problem if there has been a pump failure.

When called in for a pump re fu rb i shment project the first challenge is not knowing what the condition of the internal c o m p o n e n t s will be until the complete unit is stripped down. Externally the pumps may look to be either in a reasonable state or not worthy of being rescued.

A thorough examination of the pump in its operating environment will reveal the cause of the failure and establish whether or not the pump can be repaired in-situ. AxFlow’s engineers have a check list of actions that are adhered to during the disassembly process and it is this procedure that is crucial to identifying where problems lie. The Company goes as far as to photograph every action of the stripping down procedures as this allows component appraisal. Using this visual data is deemed essential when it comes to making recommendations as to the best course of action to be taken.

According to Tom Cooper, Service Base Manager, the goal is to get the customer back up and running as quickly as possible, but not at the expense of creating further problems that might arise in the future. Pump replacement may at first seem the easiest option, but this can be costly for the customer and may not always be the best long term solution. ■

Amongst the many domestic and commercial casualties was the Bentley Ings pumping station which suffered a power failure. The

switchgear ended up submerged in water so the pumps, which had provided many years of reliable service, stopped operating.

In response to this event, the pumping station’s owners British Coal, through the Environment Agency, have instigated an enlightened programme of works to restore the pumping station to full operating capacity and enhanced efficiency. The switchgear has now been repositioned to a higher level and the pumps are undergoing a major refurbishment programme which will result in many more years of reliable operation.

The refurbishment and retrofitting of the three Drysdale 24-inch vertical axial flow land drainage pumps and one dry weather pump incapacitated by the flood waters was awarded to AxFlow Limited by the Environment Agency’s contractor AMCO.

“The first task was to remove the pumps from the site and transport them to our Huddersfield site,” reports Mark Redgrove at AxFlow. “Once we had the pumps back in our Huddersfield workshops and stripped down we were able to assess their condition and recommend to AMCO what work needed to be carried out. Because of their continued operation and performance under the ever-watchful eye of the EA, it had not been necessary to take Drysdale water drainage pumps out of service for more than 20 years. Close inspection revealed that the pumps were almost 70 years old and it was only because of their original build quality and management by the EA that they had continued to operate. However, it was inevitable that after

all this time there was evidence of component wear.”

In a situation such as this,

the course of action often followed is either to go to the equipment manufacturer for remedial work or to purchase completely new pumps. Unfortunately, the first route was not an option as the manufacturer had long ceased to exist. The second course of action had to be considered, but on the advice of AxFlow’s engineers

AMCO and the EA considered that this would not produce the best value for money over the long term.

Given the age of the first two pumps to be inspected, AxFlow could see that the job of giving the pumps a new lease of life and improving their efficiency would be a challenge. AxFlow also found that the dry weather or ‘summer’ pump had a smaller intake diameter than that of the discharge, a factor often associated with problems of cavitation, but easily remedied by throttling-off the intake.

“Whilst both the two Drysdale pumps displayed performance wear, it was the No.3 pump that gave us the most concern,” says Mark Redgrove. “The motor was in good shape, although heavily contaminated internally with grease, and several major components required repair or replacement. The Michell bearing journal pads were badly scored and required re-metalling and finishing. Plus there was a large amount of white metal loose in the bearing housing. The line shaft bearings were badly worn and the wear on the corresponding shaft bearings meant that these had to be rebuilt to the original diameter.”

Looking at the pump end components, the impeller bush cap was found to have sheared its studs and was loose inside the pump. Consequently, the bearing and cap was badly worn. “Because the bearing cap and bearing were both worn and no longer concentric to the top bearing, we proposed line boring the casing to true-up the bore before

70-year old pumps given new life by AxFlowFew people in the UK will have forgotten the massive flooding in the Doncaster area on 25th June 2007 when around 80mm of rain fell in a 16 hour period.

’’...the impeller/shaft had been allowed to run-out far more than it should...

Michell bearing journal pads after re-metalling and fnishing

fitting an oversized bearing bush,” says Mark Redgrove. “As a result of the bearing being loose, the impeller/shaft had been allowed to run-out far more than it should, causing wear between the impeller and wear-ring. To rectify this we recommended replacement of the wear-ring. In addition, because of the excessive wear on the impeller, our advice was to braze replacement tips on each vane and then machine them back to the original diameter. Finally, we would shot blast the casing components, paint the internals with Bitumen and, as with the No.2 pump, we would replace the gland packing.”

The No.2 pump required much of the same attention and work, but it was the clearance between the impeller and the wear-ring that caused concern. When measured, the clearance measured 7.8mm on diameter, whereas the recommended clearance for this size of pump is typically around 0.9mm on diameter. To rectify this, AxFlow replaced the wear-ring, this action returning the clearance to the original diameter. AxFlow’s engineers also found that the pump end bearing was missing a sleeve, leaving a clearance of 3mm between the bearing and the shaft journal. This problem was solved by rebuilding the shaft journal and re-metalling the bearing.

The work undertaken by AxFlow addressed the engineering issues that would get the drainage pumps at Bentley Ings back into service and ensure a long and reliable working life. Even though the pumps were of a considerable age and no longer in manufacture, AxFlow showed that it had the mechanical engineering resources and pump knowledge to repair the pumps and to ensure that once repaired and installed they would give an improved and more efficient operation.

By accepting the findings of AxFlow’s examination of the pumps and what work would have to be undertaken not just to put them back into service, but also to optimise performance, the EA has ensured a sound and economical future for the pumping station for the coming 20-30 years.■

Repaired pumps as good as new ready for installation

Specifically designed to minimise the time and cost involved in maintaining a progressing cavity pump, the EZstripTM cake pump from Mono can be completely stripped down and rebuilt in just 15 minutes, without the need to disconnect or remove any pipe work.

Simon Lambert, Mono’s general manager for Europe, commented: “We were overwhelmed with the positive response we received from our customers following the launch of the original EZstripTM and we immediately began looking at other applications for this revolutionary technology.

“With over 18 years experience in sludge cake applications, our deci-sion to deveolop the new EZstripTM

cake pump was an obvious one. The new pump features a specifi-cally designed feed chamber that is disconnected by removing only a few screws and allows access to the pin joint area for removal of

any blockages or compressed cake. Once the rotor assembly is discon-nected from the screw conveyor, the rotor and stator can be removed – all in just six minutes which we think is remarkable by any stan-dards.”

The EZstripTM cake pump is de-signed with a large auger inlet and screw conveyor. The screw convey-or extends to the compression area to help push the sludge cake into the cavities of the rotor and stator and provide consistent pumping. A side inlet port also allows the addition of thin sludge for blending applica-tions or for draining the pump.

The range is available in cast iron, with a choice of rotor and stator ma-terials as well as a variety of hopper sizes and has a capacity of up to 49 m3/h and 24 bar pressure. Typical applications include thickened sludge cake (up to 40% dry solids content), dewatered sludge, lime powder dosing, sludge blending and barrier layer injection. ■
