Monarch Industries Submersible Effluent Pumps WS Series
Monarch WS Series Submersible Effluent Pumps
The Monarch WS Series represents the gold standard in residential and light commercial wastewater management. Designed for versatility and extreme durability, this comprehensive line of submersible effluent pumps ranges from 1/3 HP to 1 HP, offering solutions for standard lift requirements as well as high-pressure, high-head applications.
Whether you are installing a new residential septic system, managing a STEP (Septic Tank Effluent Pumping) system, or requiring robust dewatering for light commercial projects, the WS Series delivers. Built with Class 30 Cast Iron housings and oil-filled motors, these pumps are engineered to run cooler, last longer, and resist the corrosive nature of effluent environments.
Engineered for Non-Clog Performance
A common failure point in effluent pumps is clogging. The WS Series addresses this with advanced impeller designs. The WS30 models utilize a 3-vane impeller, while the heavy-duty WS50, WS50H, and WS100H models feature a specialized 2-vane Cast Iron impeller. These designs allow for the efficient passage of solids (ranging from 11/16″ to 3/4″ depending on the model), ensuring smooth operation without the frequent maintenance associated with plastic impellers.

Frequently Asked Questions
What is the difference between WS30, WS50, and WS100?
The primary difference is the Horsepower (HP) and Head capacity. WS30 is 1/3 HP (28′ max head), WS50 is 1/2 HP (42′ max head), and WS100H is 1 HP (90′ max head). Additionally, the WS50/100 series uses a 2-vane impeller, while the WS30 uses a 3-vane impeller.
Are these pumps automatic?
The series offers both Manual and Automatic options. Models ending in “AM” (e.g., WS50AM) come with a float switch for automatic operation. Models ending in “M” (e.g., WS50M) are manual and require a control panel or external switch.
What does “Non-Clog” mean for these pumps?
These pumps feature impellers designed to pass semi-solids without jamming. The WS30 handles up to 11/16″ solids, while the WS50/100 series handles up to 3/4″ solids, making them superior to standard sump pumps for effluent applications.
Can I use 3-phase power with these pumps?
Yes, specific high-head models (like the WS100HM-32 and WS100HM-34) are available in 3-phase configurations (208-230V or 460V). Standard models are single-phase.
