Subaru PTX301D Diaphragm Pump
July 13, 2009


Subaru’s PTX301D diaphragm pump features a 3-inch suction and discharge ports, the self-priming PTX301D pumps up to 250 gallons per minute at a maximum pressure of 21 psi. It boasts a maximum suction lift of 25 feet and a maximum lift head of 49 feet. The design completely isolates the pump mechanism from the fluid being moved, making the model ideal for pumping abrasives, slurries, re-circulated water and other high-solid-material content, up to 2 inches, that cannot be handled by a centrifugal pump. There are no moving parts, so 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 shock-reducing air cushion chamber decreases shock on the hoses.
