grouting pump

Screw pump is a single screw-type transport pump, the main working parts of his body is eccentric helical screw (called the rotor) and the inner surface of the screw sleeve double-screw surface (called the stator), its work principle is that motor drives the pump shaft rotation, the screw will rotate around its own axis, on the other hand it rolling along the inner surface of the bush, so the formation of the pump seal chamber. Once the screw turns, the liquid in the sealed chamber to move forward by a pitch. With the continuous movement of the screw, the liquid in spiral shape of a sealed chamber pressure from the sealed chamber to another, and finally out of the pump body.
