The Grundfos BM 95-20NE (product number 19661920) is a horizontal, sleeve-enclosed high-pressure booster module from the BM 95 range, built with 20 stages in the NE variant — stainless steel sleeve with external cooling jacket. 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.
