The LB series is a lightweight and robust range of single-phase contractors’ pumps used widely by tool rental companies, utilities and in the construction industry. Considered the “hire industry standard”, early models have been used since the 1970’s. The hydraulic design features a double mechanical seal, with an oil lifter, for positive seal lubrication in any operating position, with rubber and urethane components that give excellent wear resistance in site water applications that contain sand and silt in suspension. The top discharge design forms a water and air-cooling channel and this, combined with a high-performance motor, enables long periods of operation in seepage conditions. On the LB-480 and LB-800 models, the discharge can be fixed in horizontal or vertical positions to enable the user to position the outlet in the required direction and prevent obstructions from a kinked hose.
