EBARA Optima-3AS1

Automatic operation, Ebara Stainless Steel Series Drainage Sump Pumps offer you a complete comprehensive range of submersible drainage pumps for pumping slurry, dirty and semi-dirty water. Never before have benefits this large been offered in a drainage pump. The versatility and rugged construction of these pumps allow for confident use in fixed or mobile service with either automatic or manual operation.

Features are: 304 stainless construction, built-in overload with automatic reset, air-filled continuous duty motor, oil-lubricated double seal**. This submersible pump has a Noryl (plastic) impeller. Pump measures 6-3/8" Diameter at the base.

For models which include a Stainless Steel impeller and larger sizes see EPD-... models. Sizes range from 1/3 to 1-1/2HP. 

Optional low suction device 2601400110, a plastic “skirt” to allow the pump to be able to pump water down to a lower level.  The misconception keep in mind is that the starting level of the water has to still be above the impeller.  It’s not a device to help pump a very low level of water like a small leak on a floor. Allows to pump down to about 1/8" of floor. Note: If automatic operation, the float prevents the pump from pumping to a low level.  For low level operation tie the float up and run manually or use the manual version of the pump.
