The key task of external gear pumps is to convert mechanical energy (torque and rotational speed) into hydraulic energy (flow and pressure). To avoid unnecessarily high heat losses, units with high efficiencies are sought after. These are realized by means of pressure-dependent gap sealing and high-precision manufacturing technology.
