M2 Open Hopper Progressive Cavity Pump

We can design and process the rotor with various dimensions according to your requirements. The metal materials can be treated to increase hardness to HRC 65-67.

Material: NBR, NBRH, HNBR, EPDM and FKM are optional.

Various materials feature different levels of abrasion and temperature resistance.

Many universal joint types are available for selection such as pin, hygienic, flexible, ball tooth and cross pin to deal with multiple torque transfers and axial loads.

According to the working condition, packing seal and mechanical seals are optional. In order to prolong the shaft seal life, a cooling and flushing system can be added.

SEW, NORD, ABB and more high quality driving systems are optional.

Weifang Subtor as a German Subtor invested company in China, offers wide range of progressive cavity pumps and components. The T class trolley progressive cavity pump has typical applications as water pumping, sand and slurry pumping, chemical pumping, viscous fluid pumping, etc. A progressive cavity pump is a type of positive displacement pump, also known as eccentric screw pump. With German supported technology and rich marketing resources, Subtor provides quality PCP pumps with custom solutions for global clients.

1. The suction cavity is designed as a rectangular large hopper, and the connecting rod is equipped with a large spiral blade propeller device, which can effectively prevent the accumulation of the medium at the entrance of the pump, greatly improve the ratio of the medium into the rotor and the stator cavity, and improve the conveying efficiency of the pump. It is suitable for conveying materials with high viscosity, high solid content and poor fluidity, such as the cement cake with solid content of 18%-30%. Kitchen waste solid residue, biogas residue, potato residue, bean residue, fruit residue, fruit pulp, tomato sauce, fish paste, sauce, pulp, etc. The size of the hopper can be designed and manufactured according to the customer's on-site installation requirements.

2. In order to reduce the resistance of the pipeline, the pipe material should be made of stainless steel as far as possible, such as carbon steel pipes, to ensure that the inner surface is smooth and no rust: the turning radius of the pipeline should be greater than or equal to 4-5 times the diameter of the pipeline itself.

Suggestions: Hopper pump pipe diameter, according to the actual situation, usually between DN100-350 is appropriate; Try to avoid 90-degree elbows.

3. The extrusion cavity can be split, the extrusion cavity and the suction cavity body are axially separable design, and are connected with bolts, so that when replacing the rotor, as long as the extrusion cavity is disassembled, the rotor can be removed for replacement, without the need to remove the entire suction cavity body, and the maintenance is more convenient and quick.

4. The upper part of the extrusion silo of the suction chamber of the pump is close to the stator end and is provided with a water injection port (small ball valve). Before the pump runs, a small amount of water or other liquid can be added as needed to prevent the dry operation of the pump; The bottom of the suction chamber is provided with a flange structure of the discharge port, so that the remaining material in the pump can be washed out before maintenance.
