Monarch WS52H Series Submersible Sewage Pump
Monarch WS52H Series: High-Head Performance for Sewage Ejection
The Monarch Industries WS52H Series takes the rugged reliability of the standard WS sewage line and elevates it for high-head applications. Designed for residential and light commercial systems where gravity flow is not an option, the WS52HM (Manual) and WS52HAM (Automatic) models provide the lift necessary to move raw sewage to elevated septic tanks or sewer mains.
Engineered for High Lift
While standard sewage pumps are efficient at moving volume, the WS52H series is engineered to generate higher pressure, allowing for greater vertical lift. Powered by a robust 1/2 HP motor (available in 115V or 208-230V), these pumps utilize a specific impeller and volute configuration (Part #493802 and #493557) to achieve this performance without sacrificing the ability to pass sewage solids.
Heavy-Duty Cast Iron Construction
Durability is the cornerstone of the WS52H. The pump housing, volute, and motor cap are constructed from Cast Iron Class 30. This heavy material dampens noise, absorbs heat, and withstands the physical abuse of a sewage pit better than thermoplastic or sheet metal alternatives. The unit is held together by stainless steel fasteners, ensuring that the pump remains serviceable even after years of submersion in corrosive wastewater.
Advanced Motor Protection
The 1/2 HP motor sits in an oil-filled chamber (requiring 2.5 liters of dielectric oil). This design ensures the double ball bearings are constantly lubricated and aids in dissipating heat from the motor windings. The pump also features a mechanical carbon/ceramic seal (5/8″ rotary) to prevent liquid ingress, protecting the electrical components from damage.
Automatic and Manual Options
- WS52HAM (Automatic): Comes equipped with a piggyback float switch for autonomous operation, ideal for residential basins.
- WS52HM (Manual): Designed for direct plug-in or use with an external control panel, offering flexibility for custom installations.
Key Features
- High Head Hydraulics: Specialized impeller/casing design for higher lift applications.
- 1/2 HP Motor: Powerful, oil-filled motor for continuous duty and high torque.
- Solids Handling: Designed specifically for sewage and wastewater containing solids.
- Voltage Options: Available in 115V and 208-230V single-phase configurations.
- Durable Build: Cast Iron Class 30 housing with 416 Stainless Steel motor shaft.
- Serviceable: Replaceable power cords and seals (SJOW-A type cords).
Applications
- Deep Sewage Basins: Ejecting waste from deep basements where standard pumps cannot reach the sewer line.
- Pressure Sewer Systems: Pumping into pressurized mains (where applicable).
- Mound Systems: Transferring effluent or sewage to elevated drain fields.
- Long Distance Transfer: Pumping wastewater over longer horizontal distances requires higher head pressure.

FAQ Section
Q: What makes the WS52H different from the standard WS52?
A: The “H” denotes “High Head.” While the standard WS52 is designed for typical volume capabilities, the WS52H uses a specific impeller (#493802) and motor configuration designed to push sewage to higher vertical lifts, making it suitable for deep basements or mound systems.
Q: What voltages are available for the WS52H?
A: The WS52H is available in 115V (Models WS52HM/WS52HAM) and 208-230V (Models WS52HM-12/WS52HAM-12).
Q: Does the WS52H come with an automatic switch?
A: Yes, models with “AM” in the part number (e.g., WS52HAM) include a float switch for automatic operation. Models with “M” are manual.
Q: How much oil does the WS52H motor require?
A: The technical specifications indicate a requirement of 2.5 Liters of dielectric insulating oil (Part #620581), which is slightly more than the standard WS series.
Q: Is the cord replaceable?
A: Yes, the WS52H series uses a heavy-duty SJOW-A 14/3 cord (Part #225119 for 30ft models) which can be replaced if damaged, though proper sealing is required.
