Honda 3/4 HP Stainless Steel Submersible Water Pump
The Honda WSP73 3/4 HP Stainless Steel Submersible Water Pump is a compact, heavy-duty electric pump designed for dependable water removal in residential, commercial, agricultural, and general dewatering applications. Powered by a 3/4 HP, 115V motor, it delivers up to 74 gallons per minute and is designed for continuous-duty operation.
Its durable 304 stainless steel casing, top-discharge configuration, automatic non-mercury float switch, and built-in thermal protection make the WSP73 a practical choice for applications where reliable automatic pumping is important. It can also handle solids up to 3/8 inch, allowing it to move relatively dirty water and light slurry without requiring a dedicated trash pump.

Specifications are based on Honda's current WSP73 product information.
74 GPM Water Removal
The WSP73 is capable of moving up to 74 gallons of water per minute, making it suitable for a range of routine dewatering tasks. Its performance will vary according to discharge-head height, hose or pipe configuration, fittings, and other system restrictions.
The pump has a published maximum head of 54 feet and maximum pressure of 23 PSI. As pumping head increases, actual flow decreases, so the maximum 74 GPM figure should not be interpreted as the flow rate available under every operating condition.
Durable Stainless Steel Construction
Honda uses a 304 stainless steel casing on the WSP73. This material provides corrosion resistance and is well suited to equipment that spends much of its operating life in or around water.
The stainless steel construction also helps the pump withstand routine handling and demanding pumping environments while minimizing concerns about rust on the pump housing.
Automatic Float Switch
The WSP73 incorporates an automatic mechanical float switch that does not use mercury. As water rises, the float activates the pump; as the water level falls, it switches the pump off.
This feature makes the pump useful for locations where water levels fluctuate and unattended automatic operation is desirable, such as basements, window wells, drainage areas, and other low-lying spaces.
Top-Discharge Design
The pump uses a top-discharge configuration, directing the discharge connection upward from the pump body.
This arrangement can be advantageous in confined spaces because it allows the pump and discharge hose to occupy a relatively compact footprint. Honda specifically identifies the top-discharge configuration as useful where space is limited.
Handles Small Solids
The WSP73 can handle solids up to 3/8 inch in diameter. This gives it more flexibility than a pump intended exclusively for clean water, allowing it to move water containing small amounts of sediment, debris, or slurry.
It is important to distinguish this capability from a dedicated trash pump. The WSP73 is a standard submersible pump, not Honda's larger side-discharge submersible trash-pump design. For applications involving larger debris or heavy concentrations of solids, a dedicated trash pump may be more appropriate. Honda's WSP100, for example, is designed to handle solids up to 2 inches.
Built-In Thermal Protection
A thermal automatic reset helps protect the motor if it becomes overheated. If the pump reaches an excessive temperature, the protection system can interrupt operation and automatically reset after the motor cools.
This protection is particularly useful for a pump intended for continuous-duty applications, but users should still investigate the cause of repeated thermal shutdowns rather than treating the protection system as a substitute for proper operating conditions.
Continuous-Duty Operation
Honda rates the WSP73 for continuous duty. Honda specifies continuous operation in temperatures up to 104°F, with intermittent operation permitted up to 140°F.
This makes the pump suitable for applications where water needs to be moved for extended periods rather than only during short drainage cycles.
Double Mechanical Seals
The WSP73 uses tandem mechanical seals, with a carbon/ceramic upper seal and silicon-carbide/silicon-carbide lower seal configuration. Honda states that the oil-lubricated double mechanical seals help prevent seal damage if the pump is run dry.
The pump should nevertheless be operated according to Honda's instructions and should not intentionally be left running without water.
50-Foot Heavy-Duty Cord
A 50-foot heavy-duty 115V power cord is supplied with the WSP73, providing considerable flexibility when positioning the pump relative to an electrical outlet.
For safe operation, the electrical supply and extension-cord arrangement, if one is used, should meet the requirements specified by Honda and applicable electrical codes. Honda recommends GFCI protection for 115V operation.
Typical Applications
The Honda WSP73 is suited to applications such as:
Basement drainage
Window-well drainage
Garden irrigation
Decorative fountains
Water-feature maintenance
General property drainage
Light commercial dewatering
Agricultural water movement
Construction-related water removal
Emergency water removal
Honda specifically identifies basements, window wells, garden irrigation, and decorative fountains among the intended applications.
Operating Considerations
For reliable performance:
Place the pump in an appropriate location where it can remain submerged or partially submerged as required.
Connect a compatible 1.5-inch discharge hose or fitting.
Ensure the discharge path is unobstructed.
Position the automatic float switch so it can move freely.
Use an appropriate GFCI-protected electrical supply.
Inspect the power cord and pump before operation.
Keep the pump free from excessive debris.
Do not exceed the pump's rated operating conditions.
Disconnect electrical power before servicing or handling the pump.
Follow Honda's owner's manual for installation, operation, and maintenance.
Maintenance
Routine inspection helps maintain reliable operation. Check the pump periodically for:
Damage to the stainless steel casing
Blockages around the intake
Debris around the impeller
Float-switch movement
Power-cord damage
Discharge-hose restrictions
Mechanical-seal leakage
Unusual vibration or noise
If the pump repeatedly trips its thermal protection, stop using it and determine whether the cause is a blockage, inadequate water flow, electrical issue, excessive load, or another operating problem.
Benefits
74 GPM capacity provides efficient water removal.
3/4 HP motor offers a strong balance of power and portability.
115V operation allows connection to a standard electrical supply.
304 stainless steel casing provides corrosion resistance.
Automatic non-mercury float switch enables automatic water-level control.
54-foot maximum head provides useful lifting capability.
3/8-inch solids handling accommodates lightly contaminated water.
50-foot cord provides flexible placement.
Thermal automatic reset helps protect the motor.
Continuous-duty rating supports extended pumping applications.
Top discharge works well in space-constrained installations.
27-pound dry weight keeps the pump relatively manageable for portable use.
Who Is It For?
The Honda 3/4 HP Stainless Steel Submersible Water Pump is a practical choice for homeowners, contractors, property managers, landscapers, farmers, and maintenance professionals who need dependable electric water removal.
With its 74 GPM capacity, stainless steel construction, automatic float switch, 50-foot cord, thermal protection, and continuous-duty rating, the WSP73 is well suited to routine drainage and water-transfer work where a compact, automatic submersible pump is preferred.
For applications involving large debris or heavy concentrations of solids, consider a dedicated trash-pump configuration rather than this standard submersible model.
