The LB-series is a submersible single-phase portable drainage pump. Though it is a single-phase unit, the pump has the durability equivalent to three-phase drainage pumps, since the wear parts are made of abrasion-resistant materials. The top discharge, flow-thru design provides maximum motor cooling efficiency allowing continuous operation at low water levels and extended dry-run capability. Every LB model is slim design enough to be accommodated in an 8-inch pipe. The discharge direction is selectable between vertical and inclined, which prevents folding or bending of the discharge hose.

*Except for LB-1500

Automatic model with pendant float set or electrode sensor is available for LB-480 and LB-800.
