Introduction of Pumps In The Food&Beverage Field

As an important part of conveying fluid media, beverage pumps play a very important role in the food and beverage processing field. Common beverage pumps include centrifugal pumps, rotor pumps, and screw pumps. The main parameters of the pump are material viscosity, flow capacity, lift, power and rotor speed. Today we will give a brief introduction of three pumps character and difference.

The centrifugal pump is a vane pump. All parts in contact with the material, such as the pump body, pump cover, and impeller, are made of SUS316L or SUSI304 stainless steel; The motor uses the ABB brand, with protection class IP55.F insulation and wide voltage structure. It is suitable for conveying low viscosity materials such as milk, juice, syrup, high purity water and wine.

Before the centrifugal pump is started, the pump is filled with fluid, the motor drives the impeller to rotate at a high speed, and the blades drive the liquid to rotate, generating centrifugal force, and the liquid gains pressure and speed capability to achieve the purpose of conveying fluid.

The rotor pump one of the positive displacement pumps, it can be also called sanitary rotor lobe pump, there are two cam rotors with the same shape that mesh with each other and rotate. During the rotation, the two rotors will form a vacuum chamber, the vacuum chamber sucks in materials and discharges them at the outlet. The parts of the stepless speed regulating rotor pump are made of 304/316 stainless steel and other materials that meet sanitary standards. It is suitable for conveying fluids that is easy to generate foam, high viscosity and includes particles during transportation, such as tomato ketchup, syrup, cheese, cream, fruit puree and paste.

The screw pump with internal meshing is a rotor type positive displacement pump.it is composed of stator and rotor, spiral interference fit of the two form a continuous seal cavity, achieved by the rotation of the rotor motion transmission of media. It has a simple structure, uniform flow, small disturbance, carrying capacity, etc. It can transport all kinds of mixed impurities and solid particles or fibers, and can also transport all kinds of corrosive substances and high-viscosity substances and fluids, such as tomato paste, dairy cream, fruit pomace, crushed fruit pulp.
