The Grundfos BM 95-7N (product number 19913607) is a 7-stage high-pressure booster module built for reverse-osmosis and filtration duty, rated 498 US gpm at 420 ft, driven by a 60 HP three-phase motor. The pump element runs inside a pressure sleeve, so the full system pressure is contained by the sleeve rather than the pump housing.
