The screw grouting pump is a new type of single screw pump, the main working parts of which are the motor-driven screw rotor and the fixed rubber stator.

Its working principle is that when the motor drives the pump shaft to rotate, the screw rotates around its own axis on the one hand, and rolls along the inner surface of the bushing on the other hand, thus forming a sealed chamber of the pump. Every time the screw rotates one circle, the liquid in the sealed chamber advances one pitch forward.

With the continuous rotation of the screw, the liquid is pressed from one sealed chamber to another sealed chamber in a spiral manner and squeezed out of the pump body. The screw pump is a new type of liquid conveying machinery with the advantages of simple structure, safe and reliable operation, convenient use and maintenance, continuous and uniform liquid discharge, and stable pressure.

The screw grouting pump is mainly composed of motor, reducer, coupling, feeding screw, screw rotor, rubber stator, discharge seat, hopper, frame, electrical control system and other components. When equipped with an air compressor and a nozzle, it can be used as a mortar sprayer. It truly realizes multi-purpose.

The main application areas of screw grouting pumps:
Buildings, hydropower stations, tunnels, bridges, high-speed railways, subways, slopes, foundation pits, roads, railways, urban rail transit, hydropower stations, etc. Anchor grouting (grouting), consolidation grouting and backfill grouting and other anchor grouting projects. It can be used for pressure grouting projects such as soil curtain grouting during dam, slope, and soft rock reinforcement; it can also be used for spraying and protection of the bottom layer and cover layer of the inner and outer walls of urban construction projects.
