Riverside Pumps' rugged and reliable Diaphragm Pumps are sometimes called "mudhogs" for their ability to pump heavy mud and sludge, thicker than any centrifugal pump can handle. They also have the advantage of being able to run dry without damage, so they are often used to control seepage. 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 fiber core synthetic rubber diaphragm are among the reasons construction professionals choose these pumps. With a rubber diaphragm rather than TPE, you can expect longer life which may tear the TPE. Riverside is the only mud pump with a true rubber diaphragm still. 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
Brand Change Notice: Homelite is now Riverside. This pumps Homelite model number was 111DP3 as the one picture shows, these pumps have been around for decades.

Replacement diaphragm is 03438, also fits Homelite DP3 

Suction and discharge port size cannot be reduced. Due to positive pumping action of diaphragm pumps, by all mfr's, the discharge is recommended to only be 25FT long unless oversized. Discharge can not be restricted. There is no relief valve.
