Grundfos BM 32-3N Booster Module - 3 Stages (P/N 93205181)

The Grundfos BM 32-3N (product number 93205181) is a horizontal, sleeve-enclosed high-pressure booster module from the BM 32 range, built with 3 stages in the N variant — stainless steel sleeve and shaft. The pump element runs inside a pressure sleeve, so system pressure is contained by the sleeve rather than the pump housing — which is what lets a compact module work at reverse-osmosis pressures.
