Volute casing pump for horizontal or vertical installation, back pull-out design, single-stage, with ratings to EN 733, radially split volute casing, replaceable casing wear rings, volute casing with integrally cast pump feet, closed radial impeller with multiply curved vanes, single mechanical seal to EN 12756, product-lubricated carbon plain bearing, grease-lubricated radial ball bearing in the motor housing, with magnetless KSB SuPremE motor (exception: motor sizes 0.55 kW / 0.75 kW with 1500 rpm are designed with permanent magnets) of efficiency class IE4/IE5 and PumpDrive variable speed system; ATEX-compliant version available.
Heat transfer systems
Hot water circulation
Designed to deliver reliable operation with mineral and synthetic thermal oils up to 350 °C
Maximum operating reliability ensured by KSB mechanical seal with multi-spring arrangement and reliable venting during pump operation
Safety barriers: Special contour ensures reliable removal of leakage at the mechanical seal; confined sealing elements and effective heat barrier
Individual requirements are met with maximum efficiency, and operating costs are reduced: impeller trimming, variable speed operation / intelligent control by KSB frequency inverters and KSB motors up to IE5, maximum hydraulic pump efficiency and low NSPHreq
Wide range of applications through compliance with EN PN16 and ASME, ATEX-compliant version, carbon plain bearings, marine version to DNV GL and fan impeller for efficient cooling
Great ease of maintenance due to casing wear rings and back pull-out design enabling the casing to remain in the piping during maintenance.
