Subaru’s PTX301D diaphragm pump completely isolates the pump mechanism from the fluid being moved

Subaru’s PTX301D diaphragm pump’s design completely isolates the pump mechanism from the fluid being moved, making the model suited for pumping abrasives, slurries, re-circulated water and other high-solid-material content as wide as 2 inches. Featuring 3-inch suction and discharge ports, the self-priming pump propels as much as 250 gallons per minute at a maximum pressure of 21 psi. It has a maximum suction lift of 25 feet and a maximum lift head of 49 feet. The PTX301D uses a high-quality silicon carbide mechanical seal and features a replaceable diaphragm. And a 7-horsepower Subaru EX21 overhead cam engine powers the diaphragm pump.
