Characteristics of G-type single screw pump

The G-type single screw pump has many advantages compared to piston pumps, centrifugal pumps, vane pumps, and gear pumps due to its structure and working characteristics

1. Capable of transporting media with high solid content;

2. Uniform flow and stable pressure, especially at low speeds;

3. The flow rate is directly proportional to the pump speed, thus having good variable adjustability;

4. A pump with multiple uses can transport media of different viscosities;

5. The installation position of the pump can be tilted arbitrarily;

6. Suitable for transporting sensitive items and items that are susceptible to damage such as centrifugal force;

7. Small size, light weight, low noise, simple structure, and easy maintenance.

The driving methods of single screw pumps are divided into:

Backpack type single screw pump

1. Connected by an elastic coupling and driven by a variable frequency speed regulating motor

2. Connected and fixed by an elastic coupling to drive the reduction motor

3. Connected by an elastic coupling and driven by a continuously variable speed motor
