The Myers WHR series of sewage pumps feature an all cast iron construction to withstand the most extreme conditions and are designed for use in sewage and effluent applications as well as applications which require high heads. The recessed vortex impeller design provides an unobstructed passage in the volute case which results in high efficiency pumping that will handle stringy, trashy 2” solids without clogging or plugging the impeller.  The vortex impeller also greatly extends the pumps’ bearing life. This series is also available in a double seal configuration for extended motor life and additional protection against water leakage. Typical applications include residential and commercial sewage, high capacity sump, effluent, domestic wastewater and septic pumping applications.
