Liebherr Hydraulic Pump

A hydraulic pump is a mechanical device that converts mechanical power into hydraulic energy. It generates flow with enough power to overcome pressure induced by the load.The working principle of hydraulic pumps is the same for all other pumps. The pump creates a negative pressure at the inlet by mechanical action. This causes atmospheric pressure to push the liquid into the inlet of the pump. The pump then pushes the fluid into the hydraulic system.There are typically three types of hydraulic pump constructions found in mobile hydraulic applications. These include gear, piston, and vane; however, there are also clutch pumps, dump pumps, and pumps for refuse vehicles such as dry valve pumps and Muncie Power Products' Live PakTM.A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy.
