The Godwin Dri-Prime 4" x 4" (100mm x 100mm) HL4M automatic self-priming centrifugal pump is a compact, high pressure pump perfectly suited for temporary pumping under discharge pressure conditions or high discharge lifts. Capable of generating maximum flows of 1,000 gallons per minute (63.1 l/sec.) and discharge heads to 455 feet (138.7 meters) or 195 psi (13.4 BAR), the HL4M is used in temporary fire service, quarry and mine dewatering, and as a temporary replacement for permanently installed transfer pumps. Like all Godwin Dri-Prime pumps, the HL4M can prime and reprime automatically from dry to 28 feet (8.5 meters) of suction lift.
