The Ebara OPTIMA-3MS1 is a 1/3 HP Pro Drainer submersible pump — manual operation, 115 V single phase — with a 304 stainless body and engineered-thermoplastic impeller for light slurry and semi-dirty water.
The Optima is the value version of Ebara's 1/3 HP Pro Drainer: same 304 stainless casing, motor frame, and fasteners and 303 stainless shaft, with a glass-filled thermoplastic (Noryl-type) semi-open impeller in place of the EPD's stainless one. It passes 3/8" solids, handles liquids to 122°F (140°F intermittent), and delivers roughly 40 GPM at 5 ft with heads to about 22 ft. Built-in overload protection with auto reset; 20 ft cord with piggy-back plug; 11 lb. UL certified.
A compact, corrosion-resistant dewatering pump for sumps and equipment pits. Send us your application details and we'll confirm Optima vs EPD fit.
