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. The double seal configuration provides 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. Features Power range meets many applications Domestic wastewater and septic systems Light commercial sewage High-capacity fluid transfer Durable motor for long-lasting performance Oil-filled for cooler operation and constant bearing lubrication Single-phase PSC motors eliminate starting switches Recessed impeller increases bearing life Thermal overload protection with automatic reset Seal failure probe pump options available High head models available MYERS WHR SERIES (DUAL SEAL) SEWAGE PUMPS Model Comparison Chart Model Discharge (NPT Flange Vertical) HP Voltage Phase GPM Max.
