The rotator pump calls colloid  pump , trefoil pump , sole pump etc., which are widely used in food and beverages, chemicals, pharmaceutical industries. Due to the unique shape of the pump rotor and high accuracy requirements, it has few successfully produced  domestic manufacturers. Many users only have to buy imported equipment. To change this negative situation, Secretary technical research staff in our company. Use C language to have worked out rotator curve layout procedure and have input which into the processing center to make precision process. The key components of the pump to ensure the consistency of the high-precision requirements and strict requirements.

  Model TRA Cam rotor pump is designed by Boao based on traditional TR pump, to make which superior performance  more beautiful ,higher efficiency . Structure : it adopts integral coupling assembly ,which can make the machine more compact(length can be shortened 100-250 mm) and save occupying area .It is covered with stainless steel, mirror polishing, good appearance, high grade ,no occurrence of dropping.

Function optimization : it adopts integral coupling assembly, which can reduce the elastic shaft couplings power consumption ,noise and abrasion ,thus increasing efficiency. The rotor is made through extensively researching and three-dimensional CAD ,with higher efficiency ,minimum sliding and service life .

1.The character of cam and rotor transfer pump

1.compare with centrifugal pump (pump milk) : centrifugal pump because of its simple structure, low cost and has been widely used. There are some main distinguish between them : a) cam and rotor pump belongs to Volume Pump ,the transfer flow can be controlled precisely or can be made to variable capacity pump easily . And the outlet flow  is beyond the control of the centrifugal pump, with the decline in the increase of resistance  cam and rotor pump has strong self-priming power , and the centrifugal pump should  be full of water before operation .

b) speed of  cam and rotor pump  revolution is low, generally between 200rpm to 600rpm. Output materials has been steadily delivered and its components will not be destroyed . And high speed centrifugal pumps, the delivery of materials subject to powerful centrifugal force of the impact and role Therefore, it always happens that Component differs when centrifugal pump deliveries. And cam and rotor transfer pump  is the best choice to solve this problem. So it is particularly applicable to transfer Blend material and  even mixture of solid particles.

 c) cam and rotor transfer pump can be used for the transmission of high viscosity material, known as colloidal pump. And centrifugal pump could not.

d) cam and rotor transfer pump can manufactured the variety

with  higher pressure such as 1.5MPa. It is suitable for long-distance transport or high resistance transport t.

 e) cam and rotor transfer pump used to produce more complex precision, high cost, it is also the greatest disadvantage compared with the centrifugal pump.

2, compare with  screw pump (MC Pump) : Both are Volume Pump Therefore, their  performance is similar which can transfer high-viscosity material with higher transportation pressure. But the greatest flaw  of screw pump makes its unavailable for occasion of  Hygiene requirements . The flaw is  that the Worn out of  screw-sculptured surfaces covered fluorine and Rubber material , It is likely to  cause transfer material damaged by pollution. And for Streamline basic structure and no dead spots and non-metallic pieces of cam and rotor transfer pump ,so strictly speaking ,in food and beverages, pharmaceutical, and other industries with high health requirements, cam and rotor transfer pump application Especially now degree of automation of the production line increasingly faster. Meanwhile more and more use of CIP-line (local) cleaning . This demonstrates that the use of pump selection transfer pump is important.

2. Transmission: rotor pump drive generally in following forms .

a)Motor + Fix velocity ratio reduction gear : This form is simple, rotor speed is constant. So that flow is not adjustable . If Frequency transformer added, speed adjustment can be achieved.

 b) Electrical machinery friction + CVT Transmission : This depends on the speed manual adjustments to achieve its features are safe and reliable. The flow is non-automatic adjustments more difficult, speed adjust can be available only when it works .

c) Frequency Converter : + motor speed automatic adjustment can be realized in this way, is a free flow adjustments. The advantage is a higher degree of automation and easy to operate. Inverter drawback is the higher prices, smaller low-speed torque.

3. Application of pump rotor brief :

1. Beverage categories : dairy foods, latex, chocolate syrup, cheese wort, beer, soft drinks

2. Fruit concentrates : pudding, jam, jelly, tomato sauce 3. Paste products : fats and oils, etc.

4. : Facial cosmetics, detergents, hair gel, aromatic oils, etc.

5. Drug categories : Extract, emulsion, etc. pills Pulp

6. Chemical Industry : dye, fat solvents, and polymer resin
