Honda WSP73 3/4 HP Stainless Steel Submersible Pump – Automatic 74 GPM Power with 54-Foot Max Head

Overview

The Honda WSP73 is the top-tier standard submersible pump in Honda’s lineup, offering the highest vertical lift and volume in its class. Equipped with a powerful 3/4 HP motor, it delivers a robust 74 gallons per minute and can push water up to a maximum head of 54 feet. This makes it the premier choice for demanding residential and commercial drainage tasks, such as clearing deep manholes, managing large-scale garden irrigation, or protecting expansive basements from fast-seeping water.

Crafted from industrial-grade 304 stainless steel, the WSP73 is designed for extreme durability and resistance to rust and corrosion. Its top-discharge design allows it to maintain a slim 8.3-inch diameter, making it easy to install in tight sumps or narrow window wells. With a 50-foot heavy-duty power cord, this pump provides the professional reach needed for deep-well applications without sacrificing safety or performance.

Top Performance Features

• Elite 3/4 HP Motor: High-torque output designed for continuous duty, delivering superior vertical lift (54 ft.) compared to lower-horsepower models.

   

• 74 GPM Discharge Flow: Rapidly clears large volumes of water, ensuring quick recovery from flooding or efficient operation of high-flow water features.

   

• Continuous-Duty Rated: Features Class F motor insulation, allowing the pump to run 24/7 in temperatures up to 104°F—ideal for permanent pond and irrigation setups.

   

• Full Stainless Steel Construction: Unlike basic sump pumps, the WSP73 features a stainless steel casing and a stainless steel impeller for maximum abrasion resistance.

   

• Automatic Non-Mercury Switch: A reliable mechanical float switch ensures the pump activates automatically as water levels rise, without using hazardous materials.

   

• Advanced Tandem Mechanical Seals: Utilizes a double-seal system (Carbon/Ceramic upper and Silicon Carbide lower) in an oil-filled chamber to prevent motor damage even during dry-run scenarios.

   

• Built-In Thermal Protection: Includes an automatic reset switch that guards the motor against overheating, shutting the unit down safely and restarting once it has cooled.

   

• Shielded Ball Bearings: Precision-engineered top and bottom bearings reduce friction and vibration, significantly extending the service life of the internal motor.
