Seepex supplies Smart Conveying Technology Seepex has supplied eight pumps fitted with Smart Conveying Technology to United Utilities as part of continuous cost saving initiatives. The Shell Green sludge processing site takes sludge from a wide catchment area for processing at a centralized facility where it is dewatered before being used to generate energy. United Utilities asked seepex to look at the pump systems feeding the dewatering centrifuges to reduce operating costs. After a full diagnostic check of the system by seepex and UU engineers, seepex proposed a trial with a pump fitted with seepex Smart Conveying Technology (SCT). SCT is an innovation in progressive cavity pump design that increases www.worldpumps.com

uptime and offers a significant reduction of whole life costs. During the trial stator life was extended, compared to the existing pumps, by adjustment of the retaining segments which hold the 2 part stator in place. The SCT pump ran for 30% longer before the stator was replaced and this, combined with lower stator costs for this design, has generated 70% savings in spares parts costs alone. www.seepex.com
Centrifugal pump manufacturer Amarinth has further expanded its organisation to service a burgeoning market for pump spares. Over the last 12 months, Amarinth has seen orders for pump spares grow by 50% as a result of an increase in demand for direct replacement parts for the former Girldestone range of pumps which are still in operation in many plants around the world, as well as

replacement parts for use during scheduled maintenance of its own API 610 VS4, OH2 and industrial pumps. Amarinth's service also extends to re-engineering key components of existing Girdlestone pumps. Properly re-engineered components can not only significantly extend the life of a pump saving the cost of replacing and commissioning new pumps, but also improve reliability and unplanned downtime. Amarinth has enhanced its systems to guarantee the accuracy and increase the speed at which it can help users identify the correct replacement parts, particularly for pumps that may have been in operation in industrial and chemical plants for more than 20 years. www.amarinth.com
KSB Magnochem magdrive for high output April 2014 saw KSB launch the latest generation of its Magnochem mag-drive pumps. Available in 52 sizes, the new series is primarily characterised by high outputs per size ensuring extremely low energy consumption. All pump characteristics conform to the ISO 2858/EN 22 858/ISO 5199 standards. The pumps’ engineers have paid particular attention to the design of the magnetic coupling and the routing of circulation, cooling and lubricating flows. This allows the operator to choose between four operating modes ranging from a simple internal circulation to a so-called dead-end configuration with an auxiliary hydraulic system. As an option, an external heat exchanger can be installed. This means that the pump set can be optimised
for the pumping of polymerising, coagulating and crystallising as well as low-boiling fluids. The containment shrouds are available in metals such as Hastelloy or Titanium and can also be made of zirconium oxide depending on customer requirements. The latter is extremely resistant to corrosion and does not produce eddy currents when a magnetic field passes through it. Unnecessary heat losses which would reduce output and compromise pump efficiency are thus eliminated. www.ksb.com
