Official Grundfos distributor — B2B export worldwide

The Grundfos CRN is the all-stainless-steel version of the CR vertical multistage in-line centrifugal pumps: suction and discharge ports are on the same level for a compact footprint. The CRN 125 covers flow rates up to 150 m3/h (nominal 125 m3/h) and head up to 400 m, with a maximum efficiency of 82%.

All-stainless-steel construction: all parts in contact with the liquid are made of EN 1.4401 (AISI 316) stainless steel — the right 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 25 bar depending on the model.

High-efficiency three-phase IE4 motor, from 11 to 132 kW (Grundfos MG up to 22 kW, Innomotics — formerly Siemens — above). CRNE versions with integrated MGE frequency converter available on request, 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). Flange connection DN 150 (or PJE/Victaulic grooved coupling). 17 stage variants available (see table above) to match the operating point precisely.
