WORKING PRINCIPLE
3SCREW pumps are one kind of internal gearing and off-centre whrling pumps. A rotor with single screw and a stator made from rubber with double screw channel are the main parts of the pumps. When the rotor housed in the cavity makes planetary turns around the axes of the stator, the hermetic wrist between rotor and stator moves along the rotor spiral, then the medium will be transferred from the inlet to the outlet continuously, uniformly in constant capacity. Based on this feature, screw pumps are specially suitable for conveying.
When there is a requirement for sending medium in stable pressure condition and keep the structure of the medium as well as possbile, single screw pump is the most desirable one for choosing.

Features:
Given the special structure and working principle, screw pump has the following advantages:
Conveying medium with high purity of water;
Uniform flow rate and steady pressure, which is especially obvious in low speed;
The flow rate is in proportion to the speed of the pump, so it is extremely adjustable; can be installed aslant at random; samll volume and weight, low noise, in simple structure, covenient maintenance.

Application:
Single screw pump can be widely used in industrial sectors, conveying various mediums. It can be used in chemical industry, exploration and mining, shipbuilding, ceramic industry, energy industry, handing river water, paper-marking industry, medical, food, cosmetics industry, other applications in agricultural feilds and so on...
