1/3 HP Submersible Sump Pump
This 1/3 horsepower submersible pump operates on 115V AC at 60 Hz and draws 3.3 amps. It is built with a polypropylene body, a polyamide impeller, and a carbon-ceramic shaft seal for corrosion resistance. The unit requires a minimum sump pit diameter of 8 inches and has an overall height of 10 1/2 inches.
Flow rates at 5 to 20 feet of head
At 5 feet of head the pump delivers 32 gpm, falling to 23 gpm at 10 feet and 14 gpm at 15 feet. Output drops to 5 gpm at 20 feet of head, and the maximum shut-off head is 22 feet. These figures show comfortable performance for shallow residential lift, while deeper installations will see sharply reduced flow.
Installation and wiring considerations
No float switch is included, so a separate level control must be supplied and wired to the 120V circuit. The 1-1/4 inch male discharge thread connects directly to standard plumbing fittings. The compact 6-inch body diameter allows placement in tight pits, freeing up space for backup systems or additional drainage components.

Questions about this item
Will the 1/3 HP motor and 1-1/4 inch discharge connect directly to my existing 1-1/4 inch PVC discharge line?
Yes, the pump features a 1-1/4 inch male discharge outlet designed to thread into standard 1-1/4 inch PVC fittings, and the 1/3 HP motor provides flow rates of 32 gpm at 5 ft head and 23 gpm at 10 ft head.
How can I verify the pump is operating correctly once installed in the pit?
Pour water into the sump pit until the float switch you add activates the pump; confirm it moves water at the rated flow — 32 gpm at 5 ft head — and shuts off when the water level drops below the switch turn-off point.
Does the box include a float switch and check valve, or must I purchase them separately?
The pump ships without a switch or check valve; you must buy a compatible float switch for automatic operation and a 1-1/4 inch check valve to prevent backflow into the pit after each cycle.
