cavity single screw pumps

Cavity single screw pump is a kind of pump equipment used to transport high viscosity liquid or medium containing solid particles. It usually consists of a screw and a cavity.

One of the most critical components in a pump, the screw consists of a helical shaft with one or more threads. When the screw rotates, the medium is caught by the threads and moves along the axis of the screw. The gap between the screw and the cavity is very small, thus forming a sealed cavity. Through the rotation of the screw and the change of the cavity, the medium is pushed to the outlet of the pump.

The cavity single screw pump has the following advantages:
1. Suitable for the transportation of high-viscosity liquids: Due to the design features of the cavity single-screw pump, it can effectively transport high-viscosity liquids, such as colloids, pastes, etc.
2. Capable of transporting media containing solid particles: cavity single-screw pump has a larger delivery volume and smaller delivery pulsation, so it is suitable for the delivery of media containing solid particles, such as sewage treatment, construction material delivery and other fields.
3. Capable of delivering higher pressure: The cavity single screw pump can increase the pressure capacity of the pump by increasing the screw speed or increasing the screw diameter.
4. Stable operation and low noise: The cavity single screw pump adopts special screw geometry and clearance layout, which makes the pump run with low noise and small vibration.

Cavity single screw pump is suitable for many fields, including chemical industry, petroleum, food, pharmaceutical, environmental protection and so on. They are widely used in liquid transfer, slurry handling, solid waste handling, and other applications in industrial processes.
