All-stainless-steel construction: all parts in contact with the liquid are made of EN 1.4401 (AISI 316) stainless steel, the choice for aggressive and industrial liquids (acids, alkalis, reverse osmosis, demineralisation, separators). Balanced cartridge mechanical seal, maintenance-free. Liquid temperature -20 to +120 °C, operating pressure up to 40 bar depending on the model.

High-efficiency three-phase IE4 motor, from 18.5 to 200 kW (Grundfos MG up to 22 kW, Innomotics, formerly Siemens, above). Variable-speed control is possible with an external Grundfos CUE frequency converter, for constant pressure and energy savings.

Applications: water boosting and distribution, industrial process water, washing plants, boiler feed, cooling and air conditioning, irrigation, water treatment (ultra-filtration, reverse osmosis). DN 200 flange connection (or PJE/Victaulic grooved coupling). 16 stage variants available (see table above) to match the operating point precisely.
