Monarch WS100 Series Submersible Sewage Pump
Monarch WS100H Series: Maximum Power for High-Head Applications
The Monarch Industries WS100H Series represents the pinnacle of performance in the WS effluent pump line. Engineered with a powerful 1 HP motor, this series is specifically designed for high-head applications where standard pumps fall short. Whether you are pumping to a distant raised septic mound, operating a pressure sewer system, or require deep-well dewatering, the WS100H delivers the lift and reliability you need.
Extreme Lift Capabilities
The defining feature of the WS100H Series is its hydraulic performance. Capable of a shut-off head of 90 feet, this pump provides exceptional pressure. Even at a lift of 50 feet, the WS100H can still move 76 gallons per minute (GPM), ensuring your system keeps up with demand without backing up.
Heavy-Duty 1 HP Motor
To achieve this performance, the WS100H utilizes a robust 1 HP motor running at 3450 RPM. The motor is housed in an oil-filled chamber (approx. 2.5 Liters) which provides superior cooling and continuous lubrication for the bearings.
- Single Phase Options: Available in 208-230V with automatic thermal overload protection.
- Three Phase Options: Available in 208-230V, 460V, and 575V for commercial and industrial installations.
Rugged Construction
Built to withstand harsh effluent environments, the WS100H features:
- Cast Iron Class 30 Housing: Provides maximum durability and heat dissipation.
- Non-Clog Impeller: A specialized two-vane impeller designed to handle spherical solids up to 3/4 inch.
- Stainless Steel Shaft: 416 stainless steel motor shaft resists corrosion.
- Professional Sealing: Mechanical carbon/ceramic seal (Type 6, 5/8 rotary) ensures a watertight motor compartment.
Automatic and Manual Versatility
- WS100HAM (Automatic): Includes an SJE Pump Master float switch for reliable, autonomous operation.
- WS100HM (Manual): Designed for external control panels, common in commercial or three-phase applications.

FAQ Section
Q: What is the shut-off head of the WS100H?
A: The WS100H Series has a maximum shut-off head of 90 feet, making it the highest performing pump in the WS effluent series.
Q: Can I run the WS100H on 115 Volts?
A: No. Due to the high power (1 HP) requirements, the WS100H is only available in 208-230V (Single or Three Phase), 460V, and 575V configurations.
Q: Does the WS100H handle solids?
A: Yes, despite being an effluent pump, the WS100H features a non-clog impeller capable of handling 3/4″ spherical solids, allowing it to pass small debris safely.
Q: How much oil is needed for the WS100H motor?
A: The WS100H requires 2.5 Liters of dielectric insulating oil (Ref #8, Part 620581) for proper cooling and bearing lubrication.
Q: What is the discharge size?
A: The pump comes standard with a 2″ NPT discharge, but it is compatible with a 3″ NPT adaptor kit (Part #620385) if larger piping is required.
