Tsurumi’s small dewatering pump, the LB series, is designed for applications where space is tight, particularly construction.

Secured by rope or chain, an LB can be used in applications which involve narrow pipes, small tanks, deep pits and in remote locations that are difficult to reach with larger equipment.

The LB model has a fully symmetrical design with no protruding parts, allowing it to be lowered to unknown depths without any risk of snagging. With a diameter of only 187 mm, the pump's round cross-section even fits into smaller filter pipes. There is also a version with a water level sensor which is just a few millimetres longer. The pump then controls itself automatically, switching on or off depending on the water level.

The LB presses water with dirt particles up to 6 mm in size through the housing, allowing optimal cooling of the motor. The models in the series pump 225–440 l/minute and to a maximum of 17.5 m. The smallest model weighs around 10 kg dry, the largest around 30 kg.
