It relies on synchronous gears to drive two rotors installed on two shafts to rotate in opposite directions.
A small sealed cavity is formed between the rotors and the pump housing. When the rotors rotate, the air at the inlet end is exhausted to form a vacuum, and the material is sucked in.
The material filled in the cavity is continuously pushed from the inlet end to the outlet end by the rotating rotors, thus enabling continuous operation.
Material: Stainless - steel material is used, which has good corrosion resistance and hygiene. This ensures that when transporting various fluids, the pump body will not be corroded, nor will it contaminate the transported materials.
Rotor: There are various forms available, such as two - lobe, three - lobe, disc - shaped, multi - lobe, etc., which can adapt to different transportation requirements.
Sealing: Advanced sealing technologies, such as mechanical seals or packing seals, are adopted to effectively prevent medium leakage.
Drive Shaft: It is designed with a high - strength stainless - steel rotating shaft with good acid and alkali resistance. It has high strength and stiffness, which can reduce vibration and improve the service life of the mechanical seal.
High Adaptability: It can transport media with high viscosity and containing particles, and can also adapt to environments with high temperature, high pressure, and strong corrosion.
High - precision Transportation: As a positive - displacement pump, the transportation flow rate can be precisely controlled, and it can be easily made into a variable - displacement pump.
Low Noise and Low Vibration: A certain gap is maintained between the two wheels. They do not rub or wear against each other, operate smoothly, and produce low noise.
Strong Self - priming Ability: It can be started without priming and filling the pump. It can quickly create sufficient vacuum to smoothly suck the liquid medium into the pump chamber.
Easy Maintenance: There is a wear - resistant bushing inside the pump body. There are few accessories, and they are inexpensive. They can be replaced without removing the pipeline, which greatly reduces the maintenance difficulty and cost.
Food Industry: It can transport fruit juice, concentrated fruit juice, jam, jelly, tomato paste, milk, cream, syrup, etc.
Chemical Industry: It can be used to transport soap, dyes, fats, solvents, resins, petrochemical products, etc.
Pharmaceutical Industry: It can transport pill slurries, plasma, medicinal slurries, extracts, ointments, emulsions, vaccines, etc.
Other Industries: In the cosmetics industry, it transports face creams, lotions, etc.; in the paper - making and printing industry, it transports inks, coatings, etc.; in the sewage treatment industry, it transports wastewater, sludge, etc
