  • Vertical float switch activates at 9 1/2 in for automatic operation

1/2 HP Submersible Sump Pump

The Zoeller 95-0001 is a submersible sump pump rated at 1/2 HP for 115V AC operation. It uses a vertical float switch with integral electrical connection to automate water removal. The pump body is constructed from cast iron with a thermoplastic impeller. A Buna-N, carbon, ceramic and stainless steel shaft seal protects the motor.

Suited for residential sump pits

The vertical float switch requires sufficient pit diameter for free movement. The pump activates at a 9 1/2 inch water level and shuts off at 2 1/2 inches. It is not suited for applications needing higher head pressure than 26 feet or flow rates beyond 80 gpm at 5 feet of head. Buyers needing different voltage or phase requirements should look elsewhere.

Connects to 1-1/2 inch discharge piping

The unit operates on a standard 115V 60 Hz supply drawing 10.5 amps. It delivers 80 gpm at 5 feet of head, 68 gpm at 10 feet, 50 gpm at 15 feet and 28 gpm at 20 feet. The integral switch simplifies wiring by removing the need for a separate control box. The cast iron construction handles the weight of surrounding backfill in a properly sized basin.

Questions about this item

What discharge piping size must I have ready for the 1-1/2" F outlet on this pump?

You need 1-1/2 inch female-threaded discharge piping or a matching adapter to connect to the pump outlet.

Will the 115V 10.5 A motor run on a standard household circuit alongside other basement loads?

It draws 10.5 A at 115 V, so a dedicated 15 A or 20 A circuit is recommended to avoid tripping breakers with other loads.

How can I verify the float switch cycles at the correct 9-1/2 in on and 2-1/2 in off points after installation?

Fill the basin until water reaches about 9-1/2 in; the pump should start, then stop when the level drops to roughly 2-1/2 in.
