Canned Motor Pumps

KSB Aktiengesellschaft has launched totally leak-free Canned Motor Pumps for chemical and process engineering applications. The Ecochem Non-Seal range is designed to transport hazardous, aggressive, flammable and explosive fluids. The pumps are also capable of handling toxic and extremely hot or cold media as well as volatile or valuable liquids. This new type series combines KSB’s MegaCPK – a standardised chemical pump successfully employed for years in process engineering – with ground-breaking canned motors built by Japanese cooperation partner Nikkiso. The pumps’ dimensions comply with ISO 2858 and meet the requirements of the DIN/EN/ISO 15783 and API 685 standards, with economic operation being ensured via a new energy-optimised electric motor design. The low-noise motor features a corrosion-resistant can made of Hastelloy (2.4610). The new type series will be available in four standard variants featuring one design each for standard chemical applications, heat transfer fluids, polymerising or ferrite-containing fluids and a special variant for low-boiling fluids and liquefied gases. The pump sets have been designed to meet the requirements of explosion protection class II 2 G c Ex de IIC to ATEX, TR and IEC Ex and temperature classes T1 to T5, and can handle fluids at temperatures from -40°C to +400°C as standard. The maximum head is 236 m and the maximum flow rate 690 m3/h, while product-lubricated plain bearings made of pure silicon carbide or a silicon-carbide-graphite compound allow the bearing configuration to be optimally matched to the pump’s operation and the fluid handled.
