G series single screw pumps
Q=0.8-60 m³/h ( 3.52 USGPM – 264 USGPM )
P=0~1.2 Mpa (0~174 psi)
Single screw pumps are rotary positive displacement pumps. They work according to the positive displacement principle. The interference fit of the single-helix metal rotor and the double-helix elastic stator forms sealed cavitites. When the rotor moves inside the stator, the liquid moves in the axial direction from the suction port to the discharge port.
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.
