SPD Self-Primer Diaphragm

The SPD self-primer diaphragm pumps are used in a variety of applications where durable, solids handling is a must, even in applications where the pumped fluid is extremely vicious. The SPD product line features a simplex or duplex diaphragm orientation, a discharge port clean-out, an integral 30:1 gear reduction housing and a flex coupled power frame for coupling to nearly any type of driver. Diesel, gasoline, air, PTO and electric motors are available from a driver standpoint. This fluid end is designed to be used in the most aggressive of applications with solids passing capability through 3-¾ inches (95 mm).
