    Oberdorfer close coupled Self-Priming 25GPM Gray Water pump with 1HP. The pump head is made of high quality bronze for maximum corrosion resistance and is equipped with a mechanical seal and neoprene impeller. Fitted with a base mount bracket and a heavy duty handle for permanent mounting as well as portable applications. Suction lifts of 15 ft are possible when pump is fully primed. Flexible blades on the periphery of the impeller provide the pumping action. While the impeller rotates, the liquid between the blades is continuously squeezed out into the discharge port by a cam located inside the pumping chamber. The flow may be throttled or shut off for a short period without the need of a relief valve.
