Universal three-screw pump with wide application 

Product Features:

1.The screw units is rotating along with the external prime mover.

2.The spiral groove of the screw opens periodically,and the volume of suction cavity increases,resulting into a vacuum.

3.The medium is absorbed into the spiral groove and sealed in the spiral groove.

4.Along with the rotation of screw,the medium moves toward the outlet along the axial line of the screw.

5.The medium is pumped out.This is the operating principle of screw pump.


Over the years, RSP has developed into one of the screw pump manufacturers with the widest network coverage in the domestic market.

The company's nearly 500 series of products are widely used in power, metallurgy, petrochemical, shipping, building materials, machinery, environmental protection and other industries in the neighbourhood. The market covers all provinces, municipalities and autonomous regions of the country, and has established good cooperative relations with many well-known enterprises in China. RSP Yellow Pump continuously pays attention to customers'needs. In the industry, we provide tens of thousands of screw pump products to help customers solve hydraulic, lubrication, fuel, viscous liquid transportation and other issues.

Three-screw pump screw diameter is small, and the helix is double-ended, so the dynamic balance of the screw is quite good, its inertia moment is even smaller than the universal joint. Therefore, the pump can have a higher speed, resulting in less vibration and shorter starting time. Low pulsation and low sound pressure level are important characteristics of the pump. A SMF40R38 three-screw pump with discharge pressure lOMPa and rotational speed 2900r/min was tested by the Institute of Machine Tool Manufacturing Laboratory of the Research Association of Stuttgart University. The measured noise was only 57dB (A). In hydraulic elevator system, oil-immersed three-screw pump is used because of low noise. The noise of the three-screw pump with high processing accuracy can reach 60-62 dB (A), generally less than 70 dB (A), especially 50-54 dB (A) after grinding the screw helical surface, so it can be said that the noise of the motor driving the three-screw pump is usually lower than that of the motor. Low noise is a very prominent feature of the three-screw pump. Therefore, it is also widely used as a hydraulic pump in submarines.
