Working Principle: It relies on two synchronously rotating counter-rotating rotors to generate suction at the inlet during rotation, thereby drawing in the material to be transported. The material is then enclosed in the small space of the rotor chamber and transported to the outlet as the rotors turn.
Features:
Capable of transporting high-viscosity materials with particles, exerting minimal shear force on the material to maintain its original state.
Has almost no vulnerable parts, with minimal wear on components except for the mechanical seal.
Allows selection of different pump body materials, sealing materials, and transmission methods according to requirements to adapt to different working environments and medium specifications.
Working Principle: Through the close coordination of a pair of screw rotors and the pump body, materials are pushed by the screw rotors to move axially along the pump body in parallel displacement, achieving material transportation.
Features:
Causes no damage, agitation, or shearing to the material, suitable for transporting intact granular materials.
Has strong self-priming capability and does not produce water hammer effects even in the presence of gas.
Provides stable high-pressure output and can operate normally under conditions with particles, gas, or unstable flow rates.
When equipped with a frequency converter, it can freely adjust the flow rate and be used as a metering pump.
Working Principle: Utilizes the rotation of the screw to change the volume of the pump cavity, thereby inhaling and discharging materials. As the screw rotates, the material in the sealed cavity is axially pushed from the suction end to the discharge end.
Features:
Smooth transportation with uniform flow and low pulsation.
Excellent for transporting high-viscosity materials, even those with extremely high viscosity.
Has good self-priming performance and can start without priming the pump.
High efficiency, low energy consumption, and long service life.
Consider the material’s viscosity, particle size and content, temperature, humidity, etc. For example:
Rotor pumps or parallel displacement transfer pumps are suitable for transporting high-viscosity minced meat and sausage fillings.
If the material contains large particles, a pump capable of handling particle transportation is required, such as a particle rotor pump (a special type of rotor pump suitable for materials with large particles).
Determine the required transportation flow rate and pressure based on actual production needs. Different models and specifications of transfer pumps have different flow and pressure ranges. Select a pump that meets production requirements to ensure materials are smoothly transported to the designated location.
Due to its application in the food industry, the pump’s materials and structure must comply with hygiene standards. Parts in contact with materials should be made of corrosion-resistant and easy-to-clean materials such as stainless steel, and the pump’s structure should facilitate disassembly, cleaning, and disinfection to ensure food safety and hygiene.
Consider conditions such as the workspace’s size, temperature, humidity, and ventilation:
If space is limited, choose a pump with a small volume and footprint.
If the working environment is humid or contains corrosive gases, select a pump with corresponding protection grades.
