Semi-rotating wing pump

Application

The pump is suitable for the following liquids: water, diesel fuel, bunker oil, alcohol, parafine, all not aggressive liquids, greasing oil up to a viscosity of 40 °E, LPG with special shaft sealing, thermo oil in special design.

Function and operating description

The function of the pump will be performed by moving the pump shaft by swinging the hand lever and the piston wing (1) with the integrated flaps in connection with the suction divider (2) and its integrated flaps, the medium will be sucked in and discharged. The integrated flaps in the suction divider (2) and the piston wing (1) will open under the left or right side of the pump. They will close by further strokes in the opposite direction by the medium when discharging. In connection with the Semi-Rotating Piston Wing Pump and an electrical pump as compact unit the discharged medium from the electrical pump passes through the piston wing pump and opens the flaps. As soon as the flow is interrupted the flaps will close and prevent the backflow. In this case the flaps are acting as a check valve.
