Monarch WS100 Series Submersible Sewage Pump

Monarch WS100 Series Submersible Sewage Pump is a powerful 1HP solution for liquid effluent and light commercial applications, handling solids up to 11/16″. Built with a cast iron Class 30 housing and a two-vane non-clog impeller, it ensures reliable performance. The oil-filled motor chamber features double ball bearings, automatic overload protection, and a capacitor start for high torque, with thermal protection and automatic reset (single-phase). The pump uses a sealed SJOW power cord, a 416 stainless steel shaft, and a mechanical carbon/ceramic seal for durability. Stainless steel fasteners simplify maintenance, and the 2″ NPT discharge (with a 3″ adapter option) offers flexible installation. Equipped with an SJE pump master float switch for automatic operation, the WS100 Series delivers robust performance and long-term reliability for residential and commercial sewage pumping needs.
