1/2 HP Submersible Sump Pump

The Zoeller 98-0001 is a 1/2 HP submersible sump pump rated for 115V AC at 60 Hz and drawing 9.4 A. It features a vertical float switch with integral electrical connection and activates at 7 1/4 in, shutting off at 3 in. The cast iron body and plastic impeller suit residential basement drainage.

Suits shallow pits with vertical float clearance

This pump fits pits of at least 18 in diameter and needs room for the vertical float to move freely between the 3 in off point and 7 1/4 in on point. Installations with narrower pits or tight clearances that block float travel should consider a different switch style.

61 gpm at 10 ft head decides fit

At 10 ft of head the pump delivers 61 gpm, dropping to 45 gpm at 15 ft and 25 gpm at 20 ft, with a maximum head of 23 ft. Match these flow-versus-head points to your discharge height and required volume to confirm the pump meets the job.
