For the conveyance of aggressive, toxic and low-viscosity liquids, SCHERZINGER relies on external gear pumps. The function principle is ideal for any area of application: The rotor installed on the driven shaft of the gear pump transfers the rotary motion to the second rotor. By means of the rotation, a liquid volume is displaced, proportionate to the speed. In this manner, liquids themselves can be suctioned in the pump and are also pumped at high pressures. Due to the low friction value, SCHERZINGER pumps are very efficient and low-wear.
