Monarch WSV52HAM Series Submersible Effluent Pump Vortex
Monarch WSV52HAM Series: Automatic Vortex Sewage Pump
The Monarch WSV52HAM Series is a robust automatic submersible sewage pump designed for residential and light commercial wastewater applications. Distinguished by its automatic designation, indicated by the letter A in the model number, this pump comes pre-assembled with a mercury-free piggyback float switch, allowing for hands-free and reliable on and off operation based on liquid levels.
Engineered for durability and high performance, the Monarch WSV52HAM Series features rugged cast iron construction throughout, including the motor housing, pump volute, and impeller. The unit is powered by a CSA-approved 1/2 HP, 115-volt oil-free PSC motor rated for continuous duty with built-in thermal overload protection.
Vortex Impeller Technology
The standout feature of the WSV52HAM is its high-capacity cast iron vortex impeller. This design creates a strong swirling fluid action (vortex) that allows solids up to 2 inches in diameter to pass through the discharge without interfering with the impeller vanes. This ensures superior solids handling and minimizes the risk of clogging, making it an ideal choice for sewage ejection.
Key Features
- Automatic Operation: Equipped with a mercury-free piggy-back float switch for automatic water level control.
- Solid Handling: Capable of passing 2″ spherical solids thanks to the non-clog vortex impeller design.
- Heavy-Duty Build: Cast iron motor housing, volute, and impeller ensure long-term durability.
- Powerful Motor: 1/2 HP, 115V oil-free PSC motor designed for continuous duty with double ball bearings for reliability.
- Thermal Protection: Integrated thermal overload protection prevents motor burnout.
- Corrosion Resistance: Features a 300-grade stainless steel shaft and 304 stainless steel fasteners.
- Secure Sealing: Carbon ceramic mechanical seal protects the motor from fluid ingress.
- Easy Installation: Standard 2″ NPT discharge and a 20-foot power cord sealed at the motor housing.
- Warranty: Backed by a 2-Year Warranty.
Applications
- Automatic residential sewage ejection
- Basement wastewater removal
- Effluent transfer
- Dewatering applications requiring 2″ solid handling capabilities
