Progressive cavity pumps are positive displacement pumps which depend on the interference fit between the rotor in eccentric motion and the fixed rotor. This forms seal cavities that are disconnected from each other. Through the rotation of the rotor inside the stator, the seal cavities are moved axially from the inlet end of the pump to the outlet. This is how fluid mediums are conveyed using the seal cavities of the pump.
The rotor of the pump is designed and machined into various geometric shapes according to the requirements of the customer. Surface hardening or vacuum heat treatment are performed on metal components. After these treatments, the hardness of the materials can reach HRC 65-67.
Material: NBR, NBRH, HNBR, EPDM and FKM are available for selection. They cover various abrasion and temperature resistances as well as working conditions.
We provide a variety of universal joint transmission components to choose from. There are traditional pin type and pin sleeve type universal joints, as well as food hygiene class, flexible types, ball tooth types, and cross pin type joints. They can deal with various torque transmission levels and axial loads.
The shaft seals can be either packing seals or mechanical seals. The correct choice depends on the working conditions present for your application. Cooling and washing systems are available in order to extend the working life of the shaft seal.
SEW, NORD, ABB and other high quality driving systems are available to choose from.
