Riverside Pumps' Premium Series Diaphragm Pumps feature simple and durable designs proven in decades of reliable service.

The DP2 and DP3 Premium Series Diaphragm Pumps feature dependable, rugged designs that are easy to service. A simple and durable one-piece x-profile pump rod, and a superior fibercore synthetic rubber diaphragm are among the reasons construction professionals choose these pumps. The DP2 is compact and light, making it the choice of many utility contractors for seepage control. also fits Homelite DP3 111DP3 HDP3
What is a diaphragm pump?
Diaphragm pumps are positive displacement pumps. They pump a specific volume for each pump cycle. Diaphragm pumps move fluids more slowly than centrifugal pumps, but can handle mud and larger amounts of solids including abrasive materials. They also tolerate air being drawn into the pump, and can be run dry without damage. Diaphragm pumps are widely used on construction sites to control seepage in excavations, and for pumping septic systems and operating well point systems
