Solar pumping systems for reliable Water Supply in Africa

Grundfos CRI and CRN are the all-stainless-steel versions of the CR vertical multistage in-line centrifugal pumps: suction and discharge ports at the same level, for a compact footprint. The CRI, CRN 1 delivers a flow rate up to 2.4 m3/h (nominal 1 m3/h) and a TDH up to 225 m, with a maximum efficiency of 48%.

All-stainless-steel construction: the CRI 1 is made of EN 1.4301 (AISI 304) stainless steel, the CRN 1 of EN 1.4401 (AISI 316) for aggressive liquids (acids, alkalis, reverse osmosis, demineralisation). Balanced HQQE cartridge mechanical seal, maintenance-free. Liquid temperature -20 to +120 deg C, max operating pressure 22 bar.

High-efficiency IE3 three-phase Grundfos MG motor, from 0.37 to 2.2 kW. CRIE / CRNE versions with integrated MGE variable frequency drive available on request, for constant pressure and energy savings.

Applications: water boosting and distribution, industrial process water, washing installations, boiler feed, cooling and air conditioning, irrigation, water treatment (ultra-filtration, reverse osmosis with the CRN). Oval-flange Rp 1 or DN 25/32 flange connection. 22 stage variants available (see table above) to match the operating point precisely.
