What is a

G series single screw pump?

G series single screw pump is a name for progressive cavity pump in China, and it is also the earliest single screw pump in China.

Its structure is mainly a progressive cavity pump with bearing seat, and in China he has two types.

1. Without reducer

It is mainly used in sewage treatment and low viscosity medium transportation; Such pumps are usually mass-produced, so the price is often very advantageous.

2. With reducer (That is, progressive cavity pump with bearing seat.)

It is often used in the working conditions of large flow, high viscosity, poor fluidity and high pressure.

Without reducer

  • Simple structure
  • Stable operation
  • Packing / mechanical seal
  • Transport medium with good fluidity, poor abrasiveness and low viscosity.
  • Large stock
  • Fast delivery
  • Cheapness

With reducer

  • High pressure stability
  • Strong structure
  • Low noise
  • Long life cycle
  • High efficiency
  • Suitable for all kinds of media with high viscosity and solid particles
  • The size can be customized according to your requirements.
