Understanding Pump Curves # 3, Centrifugal Pumps in parallel

By Ron Astall, Union Pumps Australia

Centrifugal pumps are frequently operated in parallel to achieve higher system flows, to enhance system flexibility or to provide greater pump redundancy and hence better system availability.  For very large projects, limited availability of sufficiently large pumps or limits on driver size or electrical starting current may dictate the use of multiple pumps. There are traps for the unwary.  Simply running an additional pump in parallel may not provide the expected results.

In our last article Stable & Unstable Curves, we looked at what makes a centrifugal pump curve "stable or "unstable". We also discussed the importance of understanding your system and, in particular, how the system will only operate where the pump curve intersects the system curve, and the differences between "steep" system curves and "flat" system curves. These preceding concepts are absolutely crucial to understanding many of the issues associated with operating pumps in parallel.

To begin, we will define parallel operation and outline how to predict system performance when two or more pumps are operated in parallel. We will discuss selection rules for parallel operation and then look at how different system characteristics react to parallel pump operation.

Parallel operation

"Parallel" operation means that two or more pumps are operating with common inlet and outlet systems. This means that each pump will have the same differential head. The total flow is the sum of the individual pump flows. See Fig 1.

Predicting performance

To predict the system performance, a combined curve for all pumps can be produced by adding the individual flows from each pump curve at a common head. This is illustrated in Fig 2 below :

As with any pumping system, the system will operate where the combined curve intersects the system curve.

In this example, the Pump curves used are not identical and this highlights a likely serious operating problem. Because Pump 'A' has a higher head at zero flow, this pump will overpower Pump 'B' at low system flows. This is highlighted in Fig 3.

In this scenario, the pump with the lower head will be stalled, and assuming that a non return valve has been fitted, it will be running at closed valve with all the attendant risks and damage.

Matching pump curves for parallel operation – selection rules

The primary concern when running centrifugal pumps together in parallel is that pumps share the load safely at lower flows.

This does not mean that pumps must have identical characteristics. Groups of low flow pumps and high flow pumps are often operated together in parallel to match variable system demand. The aim is that all pumps have matching heads at low flow to prevent pumps being stalled or blocked in by the others.

1. It is most important that the zero flow or "shut valve" heads are matched for pumps that will operate together in parallel.
2. Unstable pump curves must be avoided for parallel operation, particularly where there is any chance of operation anywhere near their point of instability. Unstable pump curves present a very real risk of surging when operating in parallel.
3. Steeper pump curves are preferred for parallel operation to assist with load sharing at low flows. Pump curves that are very flat at low flow are prone to wide flow variations with minor changes in head and may make load sharing difficult. See Fig 4.

4. Be aware of minor performance variations that may change the suitability of otherwise well matched pumps. If one pump has had more use and is worn, its curve may no longer match the other pumps. Pumps using different drivers such as a steam turbine driven pump operating in parallel with an electric motor driven unit may operate at sufficiently different speeds to cause mismatch of pump curves at low flow.

Will parallel operation suit your system?

This depends on what you are trying to achieve.

If the aim is to increase and decrease system flow by operating one, two or more pumps in parallel to meet changing demand then it is important to understand the type and limitations of your system.

If your system curve is relatively "flat"; ie. mostly static difference in levels and minimal pipe friction, then operating pumps in parallel will provide a useful performance variation.

If your system is mostly friction resistance (a steep system curve) such as a closed loop circuit or a lengthy pipeline, then performance variation will be minimal. This may be a good or a bad thing depending on what you are trying to achieve.

Flat system curves

Refer Fig 5.

When the system resistance is relatively flat (not much friction), operating additional pumps in parallel will produce a useful flow increase. Incorrectly, many operators expect that flow will double if two pumps are running in parallel. This cannot happen because, when added together, the combined pump curve intersects the system curve at a higher head due to increased frictional resistance and hence each pump will be operating at a higher head and lower individual flow than when operating alone.

Steep system curves

Refer Fig 6.

When the system curve is steep (mostly friction) this steep increase in friction head as system flow increases, means that each pump will be running at a significantly higher head and the individual pump flows will be much less than in single operation. Overall, the change in flow will be small when additional pumps are switched on.

This may be frustrating if you want to increase or vary system flow by switching pumps on and off.

Conversely, this particular aspect of steep systems; such as long pipelines and closed loop recirculating systems; is very useful to pump users that need to maximise system reliability.

These users will often specify multiple combinations of pumps operating in parallel to minimise system disruption in the event of a pump failure.

Typically, in critical applications such as cooling water circuits, three pumps may be installed with the normal operating mode being two running in parallel and the third being a standby unit. If it becomes necessary to shut one of the operating pumps down, the remaining operating pump will still provide a high percentage of the system flow until the standby pump can be started.

Is parallel operation good for you?

Installing pumps to operate in parallel can be an excellent strategy.

It is however very important to understand the aim of the exercise.

Parallel pump installations are a great idea in the following circumstances:

1. Where limited availability of sufficiently large pumps or limits on driver size or electrical starting current dictate the use of multiple pumps.
2. When flow needs to be varied according to varying system demand and when the system resistance characteristic is reasonably "flat".
3. Where the use of multiple combinations of pumps operating in parallel in a "steep" system resistance will minimise potential system disruption in the event of a pump failure.

Remember:

1. It is most important that the zero flow or "shut valve" heads are matched for pumps that are to operate together in parallel.
2. Unstable pump curves must be avoided for parallel operation.
3. Steeper pump curves are preferred for parallel operation.
4. Be aware of minor performance variations that may change the suitability of otherwise well matched pumps.

Most important of all; understand your system.

Mouvex Eccentric Disc Pump

Mouvex's A Series eccentric disc pumps have incorporated a variety of upgrades to meet growing global demand, including the implementation of ISO PN16/ANSI 150 flanges. The A Series has also doubled its maximum differential pressure from 5 bar (72 psi) to 10 bar (145 psi), enabling it to be used in the safe transfer of viscous, non-lubricating, volatile or delicate fluids in a variety of new applications. The Mouvex A Series, previously available in cast iron construction, is now available in ductile iron construction—an upgrade suited for companies in the petrochemical industry, for example, who are integrating ductile iron systems into their processes. The upgraded A Series also features the availability of both Mouvex or standardized mechanical seals, which helps expedite installations regardless of location. The mechanical seal is positioned behind the piston and provides efficient shaft sealing. Mouvex A Series positive-displacement pumps enable product transfer up to 250 C (482 F). The pumps have maximum speeds to 750 rpm, maximum flow rates to 55 m/h (242 gpm), as well as suction and discharge ports from 1" through 4" in size. The A Series are positive displacement pumps and utilize eccentric disc technology, which enables self-priming and run-dry capabilities while maintaining constant flowrate regardless of changes in viscosity and pressure. Mouvex A Series pumps also maintain their initial performance over time and are ATEX-certified for use in potentially dangerous environments with the ability to run-dry for up to three minutes.

Global Pump Industry Mergers & Expansions

The concentration of the $38 billion global pump industry has again accelerated due to a number of recent acquisitions and geographic expansions, reports McIlvaine Company in Pumps: World Markets.

The top 200 companies enjoy more than 50 percent of the global industrial pump business while another 5,000 companies average less than $4 million in sales each, according to the report.

 

GE, the 19th largest pump company, will move several rungs up the ladder as it acquires Lufkin Industries, Inc., a leading provider of artificial lift technologies for the oil and gas industry and a manufacturer of industrial gears, for approximately $3.3 billion. Artificial lift, used in 94 percent of the roughly 1 million oil-producing wells around the world, helps lift hydrocarbons to the surface in reservoirs with low pressure and improves the efficiency of naturally flowing wells. Lufkin will broaden GE's oil and gas artificial lift capabilities beyond electric submersible pumps (ESPs) to include rod lift, gas lift, plunger lift, hydraulic lift, progressive cavity pumps and a sophisticated array of well automation and production optimization controls and software. The ESP category of artificial lift is the only lift segment in which Lufkin does not currently compete.

 

McIlvaine says the world's fifth largest pump company, Weir, has acquired the R Wales group of companies, a Canadian-based manufacturer of specialty rubber and wear-resistant linings for the mining, minerals processing, and oil sands industries. The acquisition was completed on Feb. 15, 2013. With Canadian facilities in British Columbia and Ontario and a U.S. facility in Arizona, R Wales designs and manufactures rubber lining for pipes, tanks, chutes and hoses, and specializes in custom rubber and urethane-molded products, including slurry pump wear parts and mill liners. In 2012, the Wales Group generated revenues in excess of C$30m. The acquisition extends Weir's aftermarket position in the production and servicing of a wide range of rubber lined wear components for the North American oil sands and mining sectors and complements the existing customer base and product portfolio.

 

McIlvaine says Weir has also advanced its global foundry supply chain strategy, completing the acquisition of the business and assets of the Cheong Foundry in Malaysia on Feb. 6, 2013. Based near Kuala Lumpur, the facility supplies castings to a number of industries, including mining and power. The acquisition enables Weir to add foundry capacity to serve the Asia-Pacific region with high quality products from a best-cost sourcing region. In addition, agreement has been reached to acquire the plant, equipment and buildings of Xmeco Foundry Pty. Ltd, a specialist large casting foundry in Port Elizabeth, South Africa. Xmeco expands Weir's capacity and capability on the African continent, enabling the full product range to be locally produced.

 

The third largest pump company, Grundfos, will expand its Indian production capacity by setting up an additional unit, according to the report. As part of the expansion plans, with an initiative of making India as the second home, the company plans to invest Rs. 230 crores in the next five years.  Grundfos India has been growing at 30-35 percent since its inception in 1998. With the turnover of Rs. 318 crores in 2012, Grundfos is looking at Rs.1000 crores turnover in the next five years.

 

Number 22 in the rankings, Pentair, is planning to invest $50 million in expanding its operations in the UAE. According to McIlvaine, Pentair wants to increase its $400 million current turnover in the UAE to $1 billion. In particular, the company is looking to invest in a new pump manufacturing facility in the region.

 

Number 28 in world ranking, Gorman-Rupp Africa, has purchased the business of Pumptron with cash generated from operations. Pumptron has been an international value-added distributor for Gorman-Rupp for over 25 years and will further enhance the company's continuing international expansion. Founded in 1986, Pumptron is a provider of water-related pumping solutions primarily serving the construction, mining, agricultural and municipal markets in South Africa and, increasingly, throughout other sub-Sahara African countries. Pumptron is headquartered in Johannesburg with operating locations in Cape Town and Durban and had approximately $10 million in revenue during its fiscal year 2012, which includes sales of Gorman-Rupp products.

 

The Gorman-Rupp subsidiary, National Pump Company, purchased American Turbine Pump Companies (ATP). Founded in 1975, ATP is a group of companies that collectively are a leading manufacturer and distributor of energy-efficient vertical turbine and submersible pumps primarily serving agricultural, municipal and industrial markets both domestically and globally. During 2011, ATP had approximately $15 million in revenue from sales of its products through its Lubbock, Texas headquarters and two other locations in Houston and Fresno, Calif.

 

ITT Corporation has dropped from the top of the leader board when it divested its Xylem companies. But it is growing again, according to McIvaine. It has signed an agreement to acquire Joh. Heinr Bornemann GmbH.  Bornemann Pumps is a global provider of highly engineered pumps and systems for the oil and gas industry. Headquartered in Germany, Bornemann Pumps has a strong international installed base of multiphase pumping systems for the oil and gas market. The company also serves the industrial, food and pharmaceutical sectors. Founded in 1853, Bornemann has a solid record of growth with estimated fiscal 2012 revenue of $115 million and employs more than 550 employees globally.

Taco, Inc., of Cranston, RI, has purchased Hydroflo Pumps of Fairview, Tenn. Taco recently dedicated a $20 million addition to its headquarters in Cranston. The company, which has sales of $200 million a year, employs about 500 people, the vast majority at the facility in Cranston, with other workers in Fall River, Mass. and Ontario, Canada. It makes valves, pumps, tanks and electronics for heating and cooling. Hydroflo is a manufacturer of vertical and submersible turbine-driven pumps. Hydroflo also operations in Culver, Ind., Marion, Ark., Grand Island, Neb., Brownfield, Texas, and Fresno, Calif.

 

CRI Pumps, a Coimbatore, India-based manufacturer and exporter of pumps, recently signed a business transfer agreement with Pumps & Process Systems of the U.K. Chief Executive Officer of CRI Chaitanya Koranne said that CRI would shift the industrial pumping solutions manufacturing facility of Pumps & Process Systems in the U.K. to Coimbatore soon. CRI Pumps' annual turnover in 2011-2012 was Rs. 850 crore ($160 million), which was expected to increase to Rs. 1,000 crore this year. Nearly 20 percent of the turnover last year was from exports, and it was expected to go up substantially with the acquisition of the U.K. company. Pumps and Process Systems had a strong presence in sectors such as mining and CRI would be able to tap the opportunities in these areas, McIlvaine says.

 

Xylem, the current No. 1 pump supplier has acquired privately held Heartland Pump Rental & Sales, Inc. for approximately $29 million. Heartland Pump, headquartered in Carterville, Ill., has been a strong business partner with Godwin in dewatering pump rental, services and systems design since 1995. Godwin is part of the Xylem portfolio.  Heartland Pump employs approximately one hundred people with branches in Evansville, Ind., Horn Lake, Miss., and Nashville, Tenn.

 

The Liebherr Group has acquired concrete pump manufacturer Waitzinger, which is based in Neu-Ulm, Germany. Waitzinger Baumaschinen was founded in 1991 and employs a staff of nearly 60. It specializes in the development and production of truck-mounted concrete pumps, trailer concrete pumps and truck mixer concrete pumps.

Rotary Peristaltic Pump

Vanton Pump and Equipment Corp.'s portable, nonmetallic Flex-I-Liner rotary peristaltic pump evacuates drums and totes containing acids, caustics, salts, chlorides, and reagent grade chemicals, without corrosion of the pump or contamination of the fluid. The self-priming design has no seals to leak or valves to clog, and the pump can run dry for extended periods without damage. Compact in size with integral handle, it fits on drum lids without protruding and has sufficient lift characteristics to operate from the floor, skid, or stand. Only two nonmetallic parts contact fluid: a thermoplastic body block and an elastomeric flexible liner that can be replaced in the field without special tools. A rotor mounted on an eccentric shaft oscillates within the flexible liner, imparting a progressive squeegee action on the fluid trapped in the channel between the liner and the body block. Flanges on the flexible liner are pressed to the side of the body block by concentric grooves on the bracket assembly and the cover plate, isolating the fluid to the channel. The pump is suitable for flows from 0.33 gallons per minute (gpm) to 40 gpm (1.25 to 151 liters/hour) and pressures to 45 psig (310 kPa) at temperatures to 250F (121C).

Flotech joins Valve Repair Council

Flotech, a leader in valve repair services in the US southeast, has joined the Valve Repair Council, an affiliate of the Valve Manufacturers Association of America.  Flotech supports the mission of the valve repair council which advocates the original equipment manufacturer (OEM ) to repairing valves.

The proliferation of valve and actuator repair and rebuild shops around the country has led in some cases to facilities that operate without adequate quality control procedures, use substandard parts and do not have access to OEM specifications.

In 1989 the member companies of the Valve Manufacturers Association of America (VMA) saw a need to promote both safety and quality in valve and actuator repair. As a result, the service operations of VMA members banded together to create the Valve Repair Council (VRC). VRC membership is open to all VMA members who have either in-house service operations or out-of-plant service facilities, as well as their authorized independent facilities.

Valve Repair Council Objectives

The Valve Repair Council was formed to provide all qualified repairers and rebuilders of flow-control equipment-who are repairing to OEM specification-with a

means to meet the following objectives:

• To promote safety through proper repair and rebuild
• To establish and promulgate guidelines for proper repair and service
• To educate manufacturers, rebuilders and customers on the importance of proper service and the dangers inherent in substandard service
• To publish a list of members' qualified service facilities for the benefit of end-users
• To provide a forum for the legal exchange of information that will advance the quality and integrity of service
• To promote open discussion among OEMs, repair shops and users on problems relating to maintenance and repair
• To cooperate with standards' development bodies and regulatory agencies in the development of appropriate standards and regulations pertaining to service

Ruhrpumpen launches magnetic driven centrifugal process pump

Ruhrpumpen has developed the SCE-M, a magnetic drive system and axial thrust balancing pump for the petrochemical industry.

The SCE-M is an overhung, single stage, radially split, end suction, heavy duty centrifugal process pump with permanent magnetic drive complying with API 685. This pump has a centreline mounted casing, intermediate housing and single suction. No seals are needed.

The pump is maintenance-free and meets the requirements of the TA-Luft (German Technical Instruction on Air Quality Control) and has a 100% leak-free performance, the company says, due to the magnet drive technology. By using a non-metallic containment shell, such as one made of zirconium oxide, magnetic losses are eliminated, increasing pump efficiency and great energy savings. The containment shell is designed for 40 bar (580 psi) at 120°C and can be used up to an operating temperature of 250°C (482°F). The magnets are made of thermally stable samarium cobalt material (Sm2Co17) and are suitable in standard for a maximum allowable operating temperature of 250°C (300°C). Special magnet drive systems for an operating temperature up to 450°C are available.

The central assembly of the magnetic drive system over the journal bearing avoids moment loadings on the journal bearing, thus avoiding eccentric loading of the inner magnet carrier during startup and shut-down.
There are more than 130 hydraulic combinations available for the SCE-M pump, and three different impellers for each pump size are available. The patent pending axial and double radial journal bearing made of sintered silicon carbide (SSiC) are available as standard.

Blackmer SMVP series mag-drive sliding vane pumps

Blackmer SMVP Pumps Provide Seal-Less, Mag-Drive Design Advantages In Liquid-Terminal Applications



Blackmer has announced that its SMVP Series Sliding Vane Pumps have been designed to combine proven sliding-vane technology with a seal-less magnetic coupling to optimize product containment when handling expensive, hazardous or hard-to-seal fluids, such as those found in liquid-terminal applications.



The seal-less design of he SMVP pumps results in zero shaft leakage, which is a crucial concern when mixing, blending, loading/unloading or packaging the many types of liquids that are found in terminal operations.



SMVP pumps are constructed of 316 stainless steel with metalized carbon sleeve bearings and non-metallic vanes for longer life. The presence of self-lubricating carbon graphite sleeve bearings means there is no metal-to-metal contact during operation, which makes the SMVP pumps ideal for dry-run priming and line-stripping duties. The SMVP pumps also feature a unique bearing and head design that allows a small quantity of pumpage to circulate through the containment can and bearing surfaces. This positive flow of fluid minimizes temperature rise for maximum bearing life. They are also equipped with samarium-cobalt magnets as standard construction. This rare earth material prevents permanent magnet degradation if adverse operating or "break-free" conditions occur.



Blackmer's SMVP Series pumps are available in six models: SMVP15, SMVP30, SMVP50, SMVP100 and SMVP200. Flow rates range from 4 to 215 U.S. gpm (15 to 813 lpm) with an operating temperature range of -40°F to 200°F (-40°C to 96°C) and viscosity range up to 5,250 cP (25,000 ssu). This versatility allows the SMVP pumps to offer the best combined characteristics of sustained high-level performance, energy efficiency, trouble-free operation and low maintenance cost.

New Vacuum Pumping Stations from Edwards

Vacuum equipment manufacturer Edwards has launched a new range of turbo pumping stations which provides users in laboratories and research centres with an easy-to-use 'plug and play' vacuum system with high pumping speeds of up to 400l/s.



The pumping stations can be ordered through a simple three-step process and arrive pre-assembled enabling users to integrate them quickly and easily.



As a standard feature, each station combines a turbo pump with a backing pump and a TIC turbo and instrument controller. Users have a choice of a backing pump to suit their application, with diaphragm pump, rotary vane pump or XDS dry scroll pump - all options are available.



The customised stations are easy to order: users simply specify the size of turbo pump, backing pump and voltage required. In addition, users can easily add instruments including active Pirani gauges, active inverted magnetron and active wide range gauges. The pumping stations are delivered already assembled and are ready to run after simple installation.



"We have extended our range of carts to include the nEXT turbo pump for the first time to give customers a wider choice of pumping speeds," says Russell Coleman, Edwards product manager, Diffuse. "Previously carts were only available up to 220 l/s but we now have products available for larger sizes, offering a range of pumping speeds from 42 l/s to 400 l/s."



"Each cart is tailored for individual needs and where the nEXT turbo pump is chosen, should users wish, they can change the oil cartridge and bearing themselves to increase the service life of the pump and reduce cost of ownership."



The nEXT turbo pumps are easy to maintain and can be serviced by the end user on site. Users can carry out interim oil lubrication changes on site with minimum specialist tooling and typically in less than five minutes. A bearing change with minimal disassembly of the pump can also be performed in less than 10 minutes using basic workshop tools and an Edwards tool kit.



nEXT pumping stations are used to create the high vacuum environments required for many R&D applications such as particle accelerators, high energy physics and plasma research, UHV systems and beam lines. The stations can be wheeled around easily providing high vacuum pumping stations that create optimum vacuum conditions wherever they are required.
