Etanorm
Horizontal volute casing pump, single-stage, with ratings and main dimensions to EN 733, long-coupled, back pull-out design, with replaceable shaft sleeves / shaft protecting sleeves and casing wear rings, with motor-mounted variable speed system. With KSB SuPremE, a magnetless synchronous reluctance motor (exception: motor sizes 0.55 kW / 0.75 kW with 1500 rpm are designed with permanent magnets) of efficiency class IE4/IE5 to IEC TS 60034-30-2:2016, for operation on a KSB PumpDrive 2 or KSB PumpDrive 2 Eco variable speed system without rotor position sensors. Motor mounting points in accordance with EN 50347, envelope dimensions in accordance with DIN V 42673 (07-2011). ATEX-compliant version available.

Technical Data
Benefits
-
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
