Working Principle and Structure of Subtor Progressive Cavity Pump
PC pump as a type of positive displacement pump works based on the interference fix between the stationary stator and the eccentric turning rotor. This interference movement forms several separated and air-proof cavities, running from the inlet to outlet along the axis because of the rotor's rotation, which results in the medium's continuous conveyance in cavities.
For the special structure and working principle, PC pump is the most suitable for the conveyance of various medium of solid particle or fiber, viscous, corrosive, shear-sensitive, mixture of gas and at different temperature.
Medium Transferred by Subtor Progressive Cavity Screw Pump
• High solid content fluid
(The solid content of sewage can reach 45%)
• Suitable for medium with viscosity up to 1,000,000 cp.
• Fluids containing fibrous materials
• Shear force or centrifugal force sensitivity medium
• Multiphase mixture of gas, solid and liquid
Usage Fields of Subtor Positive Displacement Pump
• Environmental Protection Field
• Biogas Energy Field
• Petroleum and Petrochemical Industry
• Offshore Platform
• Coal Water Slurry Field
• Mining Industry
• Paper Making Industry
• Emulsion explosive Industry
• Food, Beverage and Pharmaceuticals Industry
• Accurate Dosing Processing Industry
Notes on Type Selection of Subtor Progressive Cavity Pump
Outstanding Advantages of Subtor Hopper Screw Pump
Special designed PC Pump is to handle medium with solid content up to 30%-45% and much higher viscosity.On the basis of M2 type pump, a standard bridge breaker is added for M3 type pump,which can help the higher viscous medium entering in the suction housing and avoiding bridging phenomenon.
The solid content of fluid can be up to 45%.
Big rectangular hopper is designed as pump housing, suitable for medium with high viscosity, high solid content and poor fluidity. Coupling rod with propulsion unit by feeding screw blade, effectively feeding fluid into the conveying elements,preventing accumulation at the entrance. Suitable for mud cake with solid content 30%-45%.The size of rectangular hopper can be customized according to different installation conditions.
Wide range of raw material for choice to meet the various requirements of individual application.
Carbon steel, Stainless Steel S304, Stainless Steel S316, Stainless Steel 2Cr13, Intermediate Duplex Stainless Steel S32205, Advanced Duplex Stainless Steel S31260, Tool Steel Cr12MoV, Alloyed Carbon Steel 42CrMo are all available.
Besides, the rotor’s surface can be treated by chrome-plated, vacuum quenching or WC/CrC thermal spray welding technology to meet different abrasion and corrosion resistant requirements.
Rotors can also be designed and machined into different geometrical shapes (A Type, B Type, D Type and P Type) to be suitable for customers’ various working conditions.
Subtor has its own unique rubber formula to produce various types of quality stator.
NBR Rubber, NBRH Rubber, HNBR Rubber, EPDM Rubber are chosen for general application with high performance of abrasion and corrosion resistance, swelling resistance, oil bearing and anti-aging.
Sanitary Grade NBRF Rubber, EPDMF Rubber are selected for the special requirements in food, beverage, cosmetic and pharmaceutical industry.
FKM Rubber and PTFE Rubber are offered for the transportation of medium with extremely high temperature endurance and strong corrosive resistant property.
Several types of universal joint are available for your choice to meet the various requirements of different torque and axial load.
Pin type universal joint and pin with bushing type universal joint are the most widely used in general application with excellent performance.
Titanium alloy flexible rod universal joint are specially developed and adopted for food, beverage, cosmetic, emulsion explosive and pharmaceuticals industry, with the outstanding advantages of food grade sanitary processing, non-contamination to medium, reliable and endurable operation.
Open universal joint are strongly recommended for the medium with good lubricating property.
Cross universal joint is specially designed and the most suitable for the multi-stage pump with super higher torque and axial loading endurance property.
Packing seal and mechanical seal are offered for different working conditions.
Also there are various types and materials to choose for mechanical seal.
Germany brand Eagleburgmann mechanical seal are used for the well-known of
reliable and endurable operation.
The most widely used type of mechanical seal:
1. Single Mechanical Seal(MG1,M7N,HJ977)
2. Double Mechanical Seal(M74D, Single Mechanical Seal Back to Back Installation)
3. Cartridge Mechanical Seal
4. Material of mechanical seal: Q2Q2VGG or U2U2VGG,etc.
Gear Reducer and Motor
To ensure the pump reliable operation, the gear reducer and motor of Germany SEW brand and NORD brand is strongly recommended for the outstanding advantages of low noise, no vibration, safety working and well-known high quality and reliability.
Usually, explosion-proof motor of Dazhong or Xianda brand is recommended. ABB brand is also available, if necessary. Protection class IP55, insulation class F, explosion-proof class DIIBT4 or DIICT4.
Inlet and Outlet Connection
Inlet: Reinforced customized rectangular hopper is specially designed for M3 type screw pump with medium much easier entrance into the suction housing. The size of the hopper can be customized for your individual application.
Outlet: Flange connection, Threaded connection, Quick Release Clamp Connection are are available for your choice. Customization is also available according to your requirements.
Different flushing systems are available for individual working condition, according to API682 standard, such as Plan 31, Plan 53A, or Plan 54.
