Product Description

Single-stage volute casing pump in back pull-out design, with ratings and main dimensions to EN 733, with IEC-compatible power drive system comprising PumpDrive 2 and KSB SuPremE® motor or PumpDrive 3 (efficiency class IE4/IE5 to IEC TS 60034-2-3:2016) and motor-integrated frequency inverter. The pump is designed with replaceable casing wear rings, closed radial impeller with multiply curved vanes, single mechanical seal or double mechanical seals to EN 12756, shaft equipped with replaceable shaft protecting sleeve in the shaft seal area. The back pull-out design allows the coupling, bearing brackets and impeller to be dismantled without the need to disconnect the pump casing from the piping. Motor mounting points in accordance with IEC 60072, envelope dimensions in accordance with DIN V 42673 (07-2011). ATEX-compliant version available. Well ahead of the ErP Directive’s efficiency requirements.

  • Max. flow rate : 2321 m3/h
  • Max. head : 160 m
  • Max. allowed working pressure : 16 bar
  • Maximum allowable fluid temperature : 140 °C
  • Handling clean or aggressive fluids not chemically and mechanically aggressive to the pump materials.
  • Water supply systems
  • Cooling circuits
  • Swimming pools
  • Fire-fighting systems
  • General irrigation systems
  • Drainage systems
  • Heating systems
  • Air-conditioning systems
  • Spray irrigation systems
  • Improved efficiency and NPSHreq by experimentally verified hydraulic design of impellers (vanes)
  • Operating costs reduced by trimming the nominal impeller diameter to match the specified duty point
  • Little wear, low vibration levels and excellent smooth running characteristics thanks to good suction performance and virtually cavitation-free operation across a wide operating range
  • Large variety of materials as standard for perfectly matching the pump to the fluid handled
  • PumpDrive perfectly matched to pump and motor by default factory parameter settings
  • Motor-mounted variable speed system up to 45 kW saves space
  • Pump operation made fully transparent with PumpMeter
  • The efficiency of the motor also exceeds 95 % of the nominal efficiency when the motor runs at 25 % of its nominal power on a quadratic torque-speed curve.
  • Sustainable and environmentally friendly because no magnets based on “rare earth elements” such as NdFeB are used
