Three Screw Pump

SM series three screw pump is a volumetric pump that conveys liquid from the suction end to the discharge end through the rotation of a screw. The rotation of the screw causes the liquid to form a sealed chamber inside the pump and move forward as the screw rotates, thus realizing the transportation of the liquid.
The structure of SM three screw pump is similar to that of SN series. The pressure of SN series three-screw pump can reach 4Mpa, and the pressure of SM series three-screw pump can reach 10Mpa. In high pressure service, the SM series is preferred.
Application fields: It can be used as fuel injection, fuel supply and delivery pumps; it can also be used as hydraulic, lubrication and remote control motors; it can also be used as loading, delivery and liquid pumps in the petroleum and petrochemical industry and food industry; more applications on ships, can be do transfer pumps, ballast pumps,lubricating oil pumps and hydraulic pumps, etc.

Three Screw Pump

SM series three screw pump offer decades of optimized reliability, efficiency and adptability. The self-priming pump features hardened and polished spindles which are running in a replaceable liner. It offers a wide range of variants and applications thanks to a flexible modular system.

Hydraulic drive of the drive screws and full hydrostatic compensation of the axial thrust ensures reliable performance. The drive screw is supported either by a fluid-lubricated or by an external grease-lubricated bearing. Whether in the industrial, power, oil and gas, or maritime sectors, SM series three screw pump is a the ideal choice for demanding applications.

How to choose products

Order should provide data:
1 Medium operating temperature T
2 Operating temperature viscosity of the medium V
3 Pump inlet pressure (or vacuum) P1
4 Pump outlet pressure P2
5 Pump working flow
6 Pump installation
7 Matching requirements

SM three Screw Pump selection:
1, First of all should be based on the viscosity of the oil pump to choose the appropriate speed to ensure that the pump can meet the actual conditions of the user NPSHr inhalation.
2, Medium viscosity V > 760mm²/s, please contact with our factory, I plant to help users select the pump.
3,With the characteristic table you can get the power of the selected pump N the power of the motor is Nm.Nm≥K*N
