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.


Electricity is an important energy and driving force for social and economic development. RSP has been committed to the research and development of screw pump products and manufacturing, and has successfully provided tens of thousands of professional products and services for the power industry. In the fields of thermal power, hydropower, wind power and nuclear power, RSP screw pump products are used in fuel delivery, lubrication, top shaft hydraulic, sewage treatment system modules.


At present, we have established long-term and stable cooperative relations with many well-known domestic and foreign manufacturers of power main engine equipment, including Shanghai Electric, Dongfang Electric, Harbin Electric, etc., and have successfully entered the nuclear power field, providing reliable screw pump solutions for the development of China's nuclear power industry.

The three-screw pump is mainly composed of an active screw (abbreviated as the main screw), two driven screw (abbreviated as the slave screw) and a pump sleeve containing three screw. The main screw thread is convex double-ended and the driven screw is concave double-ended. The spiral direction of the two screw is opposite. Low-pressure three-screw pump, the main rod is cantilever type, the remaining axial force is received by the thrust bearing heat installed on the main rod, and the end of the rod is natural lubrication type. Its axial force is supported by the thrust block at the end.

Medium and high pressure triple screw pumps are usually high pressure balanced. High pressure liquid passes through deep holes in the pump sleeve to the end of the main rod and the slave rod. In order to balance the axial force on the screw, a low-pressure balance type can also be used to connect the end face of the balance piston of the slave rod at one end of the discharge chamber with the low-pressure chamber, and the residual axial force of the slave rod should be directed to the discharge chamber.

Low pressure and large flow triple screw pumps are mostly double suction pumps. They have the advantages of simple structure, self-balancing in axial direction and balancing in operation.
