Tsurumi’s small dewatering pump, the LB sequence, is designed for applications where house is tight, notably development. Secured by rope or chain, an LB can be used in applications which involve narrow pipes, small tanks, deep pits and in remote areas which would possibly be troublesome to reach with bigger tools. The LB mannequin has a completely symmetrical design with no protruding elements, allowing it to be lowered to unknown depths with none danger of snagging. With a diameter of only 187 mm, the pump’s spherical cross-section even matches into smaller filter pipes. There can also be a version with a water level sensor which is just a few millimetres longer. The pump then controls itself mechanically, switching on or off relying on the water stage. The LB presses water with filth particles up to 6 mm in size by way of the housing, allowing optimal cooling of the motor. The fashions in the sequence pump 225–440 l/minute and to a maximum of 17.5 m. ไดอะแฟรม weighs round 10 kg dry, the largest round 30 kg.
