A class progressive cavity pumps produced by Subtor feature a structural design with a bearing black, which can bear a higher axial load than traditional designs. The pump is designed to handle any transport mediums, including water, with a maximum solid content of 45%. The pumps are suitable for the following applications:
1. Food processing factories: transport jams, meat pastes, starches, chocolate, etc.
2. Sewage treatment plant: deliver desulphurized sewage, sludge, etc.
3. Oilfield Industry: convey oil and gas mixtures, oil and water mixtures, etc.
Stage: 1-12 stages
Type: single-head monoblock pump, double-head nonoblock pump
Single-head pump: 6 bar, 12 bar, 18 bar, 24 bar, 36 bar, 48 bar, 60 bar, 72 bar
Double-head pump: 5 bar, 10 bar, 20 bar

Progressive cavity pumps use positive displacement through interference between the rotor in eccentric motion and the fixed rotor. The seal cavities are disconnected and the rotation of the rotor inside the stator. The seal cavities are axially moved from the inlet to the outlet, this creates a pressure differential that causes the medium to flow to the different seal cavities.
The rotor can be designed and manufactured according to the specifications of customers. Surface hardening or vacuum heat treatments can be applied to metal materials in order to increase their hardness up to HRC 65-67.
Material: NBR, NBRH, HNBR, EPDM and FKM materials can be used for the stator as they can withstand various abrasion and high temperature resistant mediums and operational environments.
Universal joint transmission components can be produced and installed in your pump. In addition to traditional pin type and pin sleeve type universal joints, we supply hygiene class, flexible type, ball tooth type, and cross pin type universal joints, to handle the varying torques and axial loads.
Packing or mechanical seals can be installed on the shaft depending on your specific working conditions. Cooling and washing systems can also be installed in order to extending the useful life of the seal and pump in general.
SEW, NORD, ABB and other high quality driving systems are available for selection.
