The Tsurumi LB-800A is a general dewatering pump with an automatic float system. The lb-series is a single-phase, lightweight and compact dewatering pump. Adoption of semi-vortex pump design enables it to maintain the original pump performance for an extended period even If the impeller becomes worn. The discharge direction is selectable between top and horizontal, which prevents folding or bending of the discharge hose. Automatic LB-800A is accompanied by a level control unit having timer function that eliminates malfunction caused by rough water surface.
