Solar pumping systems for reliable Water Supply in Africa

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 32 covers a flow rate up to 40 m³/h (nominal 32 m³/h) and a TDH up to 280 m, with a maximum efficiency of 78%.

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 -30 to +120 °C, maximum operating pressure 28 bar.

High-efficiency IE3 three-phase motor, from 1.5 to 30 kW (Grundfos MG up to 22 kW, Siemens above). CRNE versions with integrated MGE frequency converter are 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). DN 65 flange connection. 28 stage variants available (see table above) to match the operating point precisely.
