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 185 covers a flow rate up to 220 m3/h (185 m3/h nominal) and a TDH up to 360 m, with a maximum efficiency of 84%.

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.
