Featuring 3-inch suction and discharge ports, Subaru Robin‘s self-priming PTX301D diaphragm pump pumps up to 250 gallons per minute at a maximum pressure of 21 psi. The pump has a maximum suction lift of 25 feet and a maximum lift head of 49 feet. By isolating the pump mechanism from the fluid being moved, the model pumps abrasives, slurries, re-circulated water and other high-solid material content up to two inches that can’t be handled by a centrifugal pump. With no moving parts the pump can run dry indefinitely. The positive displacement type, hermetically sealed compression chamber prevents loss of gases and liquids being moved, while the large air cushion chamber decreases shock on the hoses.
