Honda 1 HP Stainless Steel Submersible Water Pump

Description

Submerge the Honda WSP100AA Submersible Water Pump into flooded vaults or residential drainage pits to evacuate graywater fast. A 1HP continuous-duty motor moves up to 150 GPM through a 2in discharge port. The stainless casing resists pitting from harsh sump runoff, but stringy rags can still jam the vortex impeller.

The pump housing features 304 stainless steel welded to cast iron motor flanges for structural rigidity under continuous submersion. Power comes from a 115V single-phase capacitor-start electric motor pulling 10 FLA under maximum dynamic load. The machine weighs 32 lbs dry and occupies a cylindrical floor stance measuring 9in in diameter by 15in tall. Double silicon carbide mechanical seals block liquid ingress along the 303 stainless steel drive shaft.

Key Features of Honda WSP100AA

Commercial buyers seeking pump pricing for dewatering choose this unit for pit drainage. Field mechanics buy Honda WSP100AA hardware to clear standing effluent without motor stalls.

• A 1HP motor drives a vortex impeller to push 150 GPM at 10ft dynamic head.
• The 2in NPT discharge mates with standard contractor lay-flat hose or rigid PVC.
• An internal thermal overload switch cuts current before internal windings exceed 265°F.
• The 304 stainless steel motor can sheds heat into surrounding fluid during deep submersion.
• Spherical solids clearance measures 0.75in to pass gravel without binding the impeller.
• A mechanical float switch initiates pumping at 14in depth and cuts off at 4in.
• The 25ft grounded power cord connects to standard 115V jobsite power panels.

Dynamic Hydraulic Performance Testing

Bench testing confirms a shut-off head of 38ft at zero flow with line pressure peaking at 16.4 PSI. Discharge volume holds at 120 GPM against a 15ft head, pulling 9.8 FLA at 115V without thermal breaker tripping. Internal motor winding temperatures level off at 142°F after 4 hours of continuous cycling in 72°F water. Airborne noise measures under 58 dB at 3ft when submerged. The silicon carbide seal face withstands 45 PSI backpressure without showing droplet weeping past the outer barrier.

Jobsite Handling Maintenance Standards

The molded top handle balances the 32 lbs mass for lowering into tight 18in sump basins with heavy work gloves. Do not buy this pump for moving corrosive industrial chemicals, flammable petroleum fuels, or abrasive concrete slurry.

• Inspect the suction screen every 30 days to clear stuck gravel from the intake passages.
• Examine the 25ft rubber power cable every 90 days for jacket cuts or insulation tears.
• Flush the internal pump volute with clean tap water after every 50 hours of muddy dewatering.

Factory Warranty Crate Contents

Honda provides a 2-Year limited warranty against casting defects and motor failures. The factory package contains one WSP100AA submersible pump with attached 25ft power cord, an adjustable tethered float switch, a 2in discharge barb adapter, and a printed operator instructions manual.
