Submersible sump pump for water removal

The Zoeller N53 is a 3/10 HP submersible sump pump designed to keep residential sump pits free of water. It operates on 115V power and features a heavy-duty cast iron housing for durability. The unit includes a 9 ft power cord and a 1-1/2 in. FNPT discharge connection. It handles liquid temperatures up to 130 degrees Fahrenheit.

Suited for standard basement drainage not

This pump suits homeowners needing automatic water removal from a standard sump basin. It is not for applications requiring higher horsepower or flow rates beyond the 3/10 HP rating. Buyers needing a pump for corrosive chemicals or solvents should look elsewhere because the materials are rated for water and oil only. Installations requiring a discharge size other than 1-1/2 in. FNPT will need a different model.

3/10 HP motor rating determines capacity

The 3/10 HP motor is the single specification that decides if this pump matches the required water volume and lift height for the installation. A lower or higher horsepower unit will not provide the same performance curve for the same pit dimensions. Verify the pump curve against the site conditions before purchase. The 115V voltage requirement must match the available circuit.

Questions about this item

Will the 1-1/2 in. FNPT discharge connect to my existing 1-1/2 in. PVC piping without an adapter?

Yes, the 1-1/2 in. FNPT discharge threads directly onto standard 1-1/2 in. PVC or ABS fittings, so no adapter is needed.

How can I verify the pump is operating correctly after installation?

Pour water into the sump basin until the float rises; the motor should start, discharge water through the 1-1/2 in. outlet, and shut off when the level drops.

Does the package include a check valve or discharge hose, or must I purchase them separately?

The box contains only the pump with its 9 ft power cord; a check valve, discharge hose or piping, and any required fittings are sold separately.
