Tsurumi’s small dewatering pump, the LB sequence, is designed for purposes the place house is tight, significantly development. Secured by rope or chain, an LB can be used in applications which involve slim pipes, small tanks, deep pits and in remote places that are difficult to succeed in with larger tools. The LB model has a totally symmetrical design with no protruding parts, allowing it to be lowered to unknown depths with none threat of snagging. With a diameter of only 187 mm, the pump’s spherical cross-section even fits into smaller filter pipes. There is also a version with a water stage sensor which is only a few millimetres longer. The pump then controls itself routinely, switching on or off relying on the water degree. เกจวัดแรงดันpressuregauge presses water with filth particles up to 6 mm in measurement by way of the housing, allowing optimum cooling of the motor. The models in the sequence pump 225–440 l/minute and to a maximum of 17.5 m. The smallest model weighs around 10 kg dry, the biggest around 30 kg.
