PUMPS, VALVES & ACTUATORS QUALITY PUMPS FOR BOILER FEED


The KSB Movitec pumps are integral to how the boilers work, delivering a constant supply of water at the correct pressure and flow rate


Byworth Boilers has selected Movitec pumps from KSB for use in its range of UK manufactured large and medium-sized boilers

yworth Boilers is a leading independent provider of steam and hot water boiler services. Offering several ranges of large


and medium-sized boilers, the company is bucking the current trend to outsource manufacturing overseas, preferring to retain all manufacturing processes, from plate rolling to final fitting under strict quality control, at its manufacturing facility in Keighley, Yorkshire. Byworth recognises that buying a boiler is a


long-term investment, so it is important that it is as efficient as possible and easy to maintain in order to maximise the investment and product lifecycle. It goes without saying that a boiler must be capable of delivering optimum performance at all times. With its boilers employed across a range of industries including food and beverage production, heath services, pharmaceuticals, paper and board making, Byworth knows how critical the readily available supply of steam and hot water are to customers’ production requirements. Should a boiler malfunction, the impact on a customer’s processes could be catastrophic. Even though Byworth manufactures and


fabricates a considerable number of components in-house, there are always certain components that have to be out- sourced. One such component is the boiler feed pump, which has a major influence on the performance of the boiler. Jason Atkinson, Byworth’s head of technical and product development, said: “Pumps are integral to how

the boilers work because the pumps are used to feed the water into the boiler. Without a constant supply of water at the correct pressure and flow rate, the boiler simply does not work.” The most influential factor on pump


selection for Byworth is reliability and in its quest for finding a pump that it can employ across its range of boilers it opened discussions with KSB UK in 2012. The first order for a Movitec pump was placed in 2013, and since then, KSB UK has sold over 400 Movitec pumps to Byworth. Keeley O’Neill, OEM area sales manager at


KSB UK takes up the story: “We approached Byworth Boilers in 2012 with an offer to free trial a Movitec VCF4-14 pump on their own boiler system also used for training in order to test its reliability and suitability for their systems. This turned out to be a great success and subsequently Byworth started officially placing orders in 2013. They have gradually increased their spend with KSB year after year to a point where we now have in place pricing agreements and a rebate scheme.” In 2019, Byworth Hire took the decision to


install Movitec pumps on its Boiler hire units. The decision to expand its six year relationship with KSB was taken largely on the issues of fast delivery, reliability and cost. O’Neill reports that it has supplied Byworth


Boilers with many of its most popular Movitec VCF models in recent years. “However,” she said, “we have also previously supplied units from our ETA range, but these are generally


one off projects. Movitec pumps are reliable, well-built and competitively priced in the market. The key issue for Byworth is reliability, for if the pump stops the boiler working it is their reputation on the line. Then there is the issue of energy efficiency. Byworth offers the most advanced and energy efficient industrial boiler in the market and our Movitec pump makes a contribution to their efforts...” What are the factors that make the Movitec


the pump so popular? The pump series is a multistage vertical high-pressure centrifugal pump in ring-section design with suction and discharge nozzles of identical nominal diameters arranged opposite to each other (in-line design) and close-coupled. Designed with hot water and cooling water recirculation, boiler feed, fire-fighting and pressure booster systems in mind, it offers users a range of energy-saving features, and delivers demand- driven operation. With lower NPSH values, it provides


dependable pump operation and operating reliability capable of delivering pressure up to 40 bar and flow rates of 190m³/h. Occupying only a small footprint, so suitable for incorporation into plant systems, the Movitec is easy to maintain. Seals are easy to replace, and EasyAccess or cartridge seals can be replaced without the need to remove the motor. The KSB Movitec plays an important role in


saving energy at component level due its hydraulic system and maximum efficiencies. The pumps are equipped with the economical
