Monarch Industries WS50H Series Submersible Effluent Pumps – Non Clog
Monarch Industries WS50H Series Submersible Effluent Pumps: High-Head Performance for Demanding Systems
The Monarch Industries WS50H Series Submersible Effluent Pumps is a specialized line of 1/2 HP submersible effluent pumps designed specifically for high-head applications. Unlike standard effluent pumps, the WS50H is engineered to generate significant lift of up to 63 feet, making it the ideal choice for deep residential septic systems, mound systems, and light commercial applications where gravity flow is not possible. Built with rugged Cast Iron Class 30 construction, this pump series combines lasting durability with advanced hydraulic performance.
Precision Non-Clog Engineering
Reliability is essential in wastewater transfer. The Monarch Industries WS50H Series features a specially designed two-vane non-clog impeller made from Cast Iron Class 30. This impeller is engineered to pass spherical solids up to 3/4 inch in diameter, significantly reducing the risk of jamming and ensuring smooth, uninterrupted operation in effluent environments containing soft debris.
Powerful High-Torque Motor
At the core of the WS50H is a high-speed 3450 RPM motor housed in an oil-filled chamber. This design ensures optimal heat dissipation and continuous lubrication for the double ball bearings. The motor uses a capacitor start design for high starting torque, allowing the pump to engage instantly even under load.
For added protection, the single-phase motor includes automatic thermal overload protection with automatic reset, safeguarding the unit from overheating during extended run cycles.
Built to Last
Every component of the Monarch Industries WS50H Series is selected for long-term reliability. The motor shaft is constructed from 416 Stainless Steel to resist corrosion, while the mechanical seal uses a carbon and ceramic face, Type 6, 5/8-inch rotary, to prevent liquid ingress. Stainless steel fasteners are used throughout the assembly, keeping maintenance and serviceability straightforward even after years of continuous submersion.
