Portable Dewatering Pumps TSURUMI LB/LB-A series

Tsurumi 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
Feature
– Powerful pumps built with durable materials in an easy handling design
– Top discharge provides maximum motor cooling efficiency allowing continuous duty operation at low water levels and extended dry-run capability
– LB-480A / LB-800A features Automatic Water Level Sensor that performs like the non-automatic pump with no special float installation required

Tsurumi LB-A Series is a submersible single-phase automatic portable drainage pump. An innovative electrode type relay unit attached to the pump automatically starts and stops the pump to eliminate dry-running. This mechanism greatly reduces power consumption and extends operating life. Though the pump is a single-phase unit, it 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. The slim design allows the pump to be placed in a confined space. The discharge direction is selectable between vertical and inclined, which prevents folding or bending of the discharge hose.
Feature
– Pump continues to run while the electric probe remains submerged.
– When the water surface falls below the electric probe, timer starts to count about one minute.
– Pump stops in about one minute after the water level falls.
– When the water level rises to contact the electric probe, pump starts operating again.
