Monarch WS100H Series Submersible Effluent Pumps – Non Clog

Engineered for reliability and heavy-duty performance, the Monarch WS100H Series Submersible Effluent Pumps represent the pinnacle of light commercial and residential wastewater management. Part of the renowned WS Series, these pumps are specifically designed for liquid effluent pumping applications where high head and durability are non-negotiable.

The WS100H series stands out with its robust Class 30 Cast Iron construction, ensuring long-term resistance against corrosion and wear. Whether you are managing a residential septic system or a light commercial sewage setup, the WS100H delivers the high-torque performance required to move effluent efficiently. With a solids-handling capacity of up to 11/16″ diameter, these non-clog pumps are built to prevent jams and minimize maintenance downtime.

Heavy-Duty Construction & Design

The core of the WS100H is its motor and pump housing, crafted entirely from Cast Iron Class 30. This rigid structure houses an oil-filled chamber that provides superior heat dissipation and permanent lubrication for the double ball bearings. The 1 HP capacitor start motor is designed for high starting torque, ensuring the pump activates reliably even under demanding load conditions.

Advanced Non-Clog Impeller Technology

Efficiency meets durability with the WS Series impeller design. The WS100H models utilize a specialized two-vane Cast Iron Class 30 impeller. This solids-handling, non-clog design allows for the smooth passage of effluent and suspended solids, significantly reducing the risk of system backups compared to standard plastic impellers.

Key Features

  • Robust Build: Motor and pump housing constructed from Cast Iron Class 30.
  • Powerful Motor: 1 HP, oil-filled chamber with automatic overload protection and thermal auto-reset.
  • Non-Clog Impeller: Solids handling cast iron impeller (2-vane design for WS100H).
  • Durable Shaft: 416 Stainless steel motor shaft for corrosion resistance.
  • Superior Sealing: Mechanical carbon/ceramic Type 6, 5/8 rotary seal.
  • Cord Protection: Power cord sealed at motor housing (Uses SJOW for WS100H).
  • Solids Handling: Capable of passing solids up to 11/16″ in diameter.
  • Discharge: Standard 2″ NPT discharge (Adaptor kit for 3″ NPT available).
  • Fasteners: Stainless steel fasteners throughout for easy serviceability.

Typical Applications

The Monarch WS Series is versatile and suited for a wide range of water systems:

  • Residential Effluent Pumping
  • Light Commercial Sewage Systems
  • Sump and Sewage Removal
  • High Head Dewatering Applications
  • Septic Tank Effluent Pumping (STEP) systems

Frequently Asked Questions

What is the solids handling capacity of the WS100H pump?

The Monarch WS100H series pumps are designed with non-clog impellers capable of handling spherical solids up to 11/16″ in diameter.

Does the WS100H pump come with a float switch?

Yes, models designated with “AM” (e.g., WS100HAM) are automatic and include a float switch (Mercury-Free SJE Pump Master). Models designated with “M” are manual and do not include a switch.

What type of oil does the WS series motor chamber use?

The motor chamber is oil-filled for heat dissipation and lubrication. It uses approximately 2.1 liters of Dielectric insulating oil.

What is the difference between WS50 and WS50H?

The “H” in WS50H and WS100H stands for “High Head.” These models are designed to pump fluid to greater vertical heights compared to the standard WS50 models.

Can I change the discharge size on this pump?

The standard discharge is 2″ NPT. However, an adaptor kit is available to convert the discharge to 3″ NPT if required for your application.
