Monarch Industries Submersible Sewage Water Pump WS102H: Heavy-Duty Submersible Effluent & Sewage Pumps
The Monarch Industries Submersible Sewage Water Pump WS102H is engineered for reliability in the toughest residential and light commercial environments. Whether you are managing liquid effluent or require a robust solution for sewage applications, the WS Series (including WS30, WS50, WS100, and the high-performance WS102H) delivers consistent power and durability.
Constructed from Class 30 Cast Iron, these pumps are designed to withstand harsh operating conditions while effectively handling solids. With a variety of horsepower options ranging from 1/3 HP to 1 HP, and high-head capabilities, the WS Series is the industry standard for wastewater management.
Key Features and Construction
- Durable Build: Both the motor and pump housing are crafted from Cast Iron Class 30, ensuring superior heat dissipation and longevity.
- Non-Clog Impeller: Features a Cast Iron Class 30 impeller designed for solids handling. The WS30 utilizes a three-vane design, while the WS50, WS50H, and WS100H utilize a two-vane design for efficient waste movement.
- Premium Sealing: Equipped with a mechanical carbon/ceramic Type 6, 5/8″ rotary seal to prevent leaks and protect the motor.
- Motor Protection: The oil-filled chamber provides excellent cooling and includes automatic overload protection with a double ball bearing design. The capacitor start motor is engineered for high torque and features automatic reset (single-phase models).
- Corrosion Resistance: The motor shaft is made from 416 Stainless Steel, and stainless steel fasteners are used throughout the unit for easy serviceability and rust prevention.
- Reliable Activation: Available with a mercury-free float switch for automatic on-off operation. Options include piggyback style (WS30) or SJE Pump Master (WS50, WS50H, WS100H).
- Versatile Discharge: Standard 2″ NPT discharge with an optional adaptor kit available for 3″ NPT requirements.
Common Applications
- Residential Sewage: Basement bathroom additions and septic tank effluent pumping.
- Light Commercial: Waste transfer for small businesses and facilities.
- Effluent Systems: Mound systems and low-pressure pipe systems.
- Dewatering: General high-volume water removal.

Frequently Asked Questions
What is the difference between Manual and Automatic WS pump models?
Automatic models (suffixed with “AM” or “HAM”) include a float switch that turns the pump on and off based on water levels. Manual models (suffixed with “M” or “HM”) require an external control panel or switch to operate and do not have a built-in float.
What type of oil does the Monarch WS series use?
The WS series motors are oil-filled for cooling and lubrication. They use Dielectric Oil. The standard WS30/50 series requires approximately 2.1 liters, while the larger WS52/102 series requires 2.5 liters.
What size solids can the WS Series pumps handle?
The solid handling capacity depends on the model:
- WS30 models: up to 11/16″ solids
- WS50, WS50H, and WS100H models: up to 3/4″ solids
