The Honda Diaphragm Pump is one of the most rugged and durable pump models available. The Honda self-priming, positive displacement diaphragm pump offers "run dry" capability and is ideally suited for muddy water, sludge or any water with a high percentage of solids. This pump offers an easy-starting, durable, Honda commercial-grade OHV engine. Superior performance and durability are the result of a unique combination of features including die cast aluminum case, air cushion chamber, special rock channel that allows solids to easily pass, spring-protected connecting rod to prevent case damage, rugged neoprene diaphragm with nylon insert, and the ability to pass solids up to 2.4". With the standard wheel kit for easy transport, this pump offers an exceptional value for construction, water treatment, and agricultural applications.
