Monarch Industries Submersible Sewage Pump WS 102
Monarch WS102 Series: 1 HP Industrial-Strength Sewage Pumping
The Monarch Industries WS102 Series is a heavy-duty 1 HP Submersible Sewage Pump designed for demanding residential and light commercial wastewater applications. While sharing the same rugged DNA as the smaller WS52 series, the WS102 delivers double the horsepower, making it the superior choice for deep installations, longer pipe runs, and systems requiring reliable solids handling performance.
Heavy-Duty 1 HP Motor
At the core of the WS102 is a powerful 1 HP motor, available in a wide range of voltage configurations to suit specific installation requirements. Whether you need a standard single-phase 230V unit for a home or a three-phase 460V/575V unit for a commercial facility, the WS102 series has a configuration to match. The motor is housed in an oil-filled chamber (approx. 2.5 Liters capacity), ensuring the double ball bearings are continuously lubricated and keeping the motor cool during heavy duty cycles.
Rugged Cast Iron Construction
Durability is non-negotiable in sewage pumping. The WS102 features a Cast Iron Class 30 motor housing and pump volute. This robust construction provides excellent heat dissipation and stands up to the corrosive environment of a sewage pit far better than plastic alternatives. The pump is assembled with stainless steel fasteners, ensuring that maintenance is possible even after years of service.
Versatile Configurations
The WS102 Series is available in several variations to meet hydraulic needs:
- Standard Sewage (WS102M/AM): Designed for typical sewage ejection.
- High Head (WS102HM): Designed for applications requiring higher vertical lift.
- Operation: Available in Manual (M) models for control panels and Automatic (AM) models with float switches.
Key Features
- Horsepower: 1 HP (Standard and High Head options).
- Construction: Cast Iron Class 30 Housing and Volute.
- Motor: Oil-Filled for cooling and lubrication.
- Shaft: 416 Stainless Steel.
- Seal: Mechanical Carbon/Ceramic (5/8″ I.D.).
- Impeller: Non-clog design (Specific Part #493230 or #493803 depending on model).
- Voltage Options: 115V, 208-230V, 460V, 575V (Single and Three Phase).
Applications
- Commercial Sewage Ejection: Ideal for small commercial buildings requiring 3-phase power.
- Deep Residential Basins: Provides the power needed to lift sewage from deep collection pits.
- Septic Transfer: Reliable transfer of raw sewage to septic tanks or sewer mains.
- Dewatering: High-volume dewatering in environments with debris.

FAQ Section
Q: What is the difference between WS102 and WS52?
A: The primary difference is power. The WS102 is a 1 HP pump, while the WS52 is a 1/2 HP pump. This allows the WS102 to handle higher head pressures and potentially longer duty cycles.
Q: What voltage does the WS102 require?
A: The WS102 is available in multiple voltage configurations including 115V, 208-230V (Single Phase), and 208-230V/460V/575V (Three Phase). You must check the nameplate or order code to confirm the voltage of your specific unit.
Q: Does the WS102 come with a float switch?
A: WS102AM models are “Automatic” and include a float switch. WS102M models are “Manual” and do not include a switch (usually used with a control panel).
Q: How much oil does the WS102 motor hold?
A: The WS102 motor chamber requires 2.5 Liters of dielectric insulating oil (Part #620581) to properly lubricate the bearings and cool the 1 HP motor.
Q: Is the cord replaceable?
A: Yes, the cords are replaceable. Ref #1 in the parts list provides options for 20ft and 30ft replacement cords depending on the voltage and phase of the pump.
