Screw Rod Pump

The screw pump is a new type of pump working according to the rotation engagement volume type principle.

Screw pump is characterized by stable flow, small pressure pulsation, self-absorption capacity, low noise, high efficiency, long life and reliable operation.

Its outstanding advantage is that it can transport high viscosity medium without forming whirlpool when transporting medium.

Screw pump reaches food grade, also can feed edible oil, wine,beer, sugar sauce, and so on.

| Product Description

The screw pump is a new type of pump working according to the rotation engagement volume type principle.


Screw pump is characterized by stable flow, small pressure pulsation, self-absorption capacity, low noise, high efficiency, long life and reliable operation.

Its outstanding advantage is that it can transport high viscosity medium without forming whirlpool when transporting medium.


Screw pump reaches food grade, also can feed edible oil, wine,beer, sugar sauce, and so on.


| Product Components

The main working parts are eccentric screw (rotor) and fixed sleeve (stator). Due to special geometrical shapes of the two parts, individual sealing cavities are formed. The media are axially and evenly pushed to flow with low internal flow speed. The volume remains unchanged and the pressure is stable. Therefore, no eddy current and stirring will occur.

| Product Features

High Viscosity Handling


Effective for pumping high-viscosity liquids, slurry and fluids containing solid particles.

Self-Priming


The pump can operate in a self-priming manner, which allows it to start pumping without filling.

Constant Flow Rate


The flow rate remains consistent regardless of changes in pressure, which is beneficial for metering applications.


Gentle Pumping Action


Ideal for delicate fluids like emulsions which can be damaged by more aggressive pumping mechanisms
