Honda WSP100 1 HP Stainless Steel Submersible Trash Pump – Automatic 150 GPM Industrial Flow & 2-Inch Solids Capability

Overview

The Honda WSP100 is the flagship of the submersible lineup, a heavy-duty electric trash pump engineered for the most demanding dewatering environments. Driven by a formidable 1 HP motor, this pump is a high-volume solution capable of moving a staggering 150 gallons per minute. Unlike standard utility pumps, the WSP100 is specifically designed to swallow suspended solids up to 2 inches in diameter, making it the primary choice for clearing flooded construction trenches, managing wastewater, or draining debris-laden basins.

Encased in an industrial-grade 304 stainless steel housing, the WSP100 is built to resist the corrosive effects of slurry and chemical-heavy water. Its side-discharge configuration is optimized for high-flow efficiency, ensuring that mud, grit, and debris are moved quickly without clogging. With a 25-foot heavy-duty cord and a "plug-and-play" 115V design, it offers professional-grade power with unmatched setup convenience.

Top Performance Features

• Massive 2-Inch Solids Capability: Equipped with a specialized single-channel stainless steel impeller that allows the pump to move murky, debris-filled water without internal damage.

   

• 150 GPM High-Flow Discharge: Moves water at nearly triple the speed of standard utility pumps, ensuring rapid recovery from flooding or sewage overflows.

• Continuous-Duty Rated Motor: Featuring Class F insulation, this motor is built for 24/7 operation—perfect for permanent sump installations or constant-run fountains.

   

• 304 Stainless Steel Construction: Every structural component is designed to withstand rust and abrasion, significantly reducing maintenance costs over the life of the pump.

   

• Mercury-Free Automatic Float Switch: An environmentally safe mechanical switch provides autonomous operation, activating the pump only when necessary.

   

• Tandem Mechanical Seal System: Features oil-lubricated dual seals (Carbon/Ceramic upper and Silicon Carbide lower) to prevent water from penetrating the motor housing.

   

• Integrated Thermal Reset: Protects your investment by automatically shutting down during an overheat event and restarting once the motor reaches a safe temperature.

   

• Extended 25-Foot Reach: The heavy-duty power cord provides ample flexibility for deep-pit installations without the need for unsafe extension cords.
