Application
The Subtor V Class progressive cavity pump features a connecting rack and thrust bearing. This type of bearing is designed to bear the axial load during operation in order to protect the deceleration motor from damage. It is suitable for high pressure pumping applications in oil transportation, particularly for long distance operations. The maximum working pressure of the pump is 72 bar and the maximum flow capacity is 300 meters cubed/hour.
The pump can handle any medium including water with 45% or less solid content.

Operation theory of progressive cavity pump
This progressive cavity pump is a volumetric pump. It operates through the interference fit of the eccentric rotor and the fixed stator, creating an interconnected seal cavity. When the rotor rotates, the sealing cavity moves between the inlet and outlet. This creates a pressure differential that causes the medium to move rapidly through the pump.

Rotor
The rotor can be designed and processed with various shapes according to customer requirements. The metal materials can be specially treated in order to increase hardness to HRC 65-67.
Stator
Material: NBR, NBRH, HNBR, EPDM and FKM are optional.
Different materials are suitable for different levels of working condition.
Universal joint
Various types of universal joints are available for selection, such as pin, hygienic, flexible, ball tooth and cross pin to deal with multiple torque transfer levels and axial loads.
Seal
Packing or mechanical seals are optional. In order to extend the working life of the shaft, a cooling and flushing system can be installed.
Driving system
SEW, NORD, ABB and more high quality driving systems are optional.
