working principle

Rotor pump is also known as colloid pump, clover pump, sole pump, etc. In the process of rotation, two rotors (2-4 teeth) which rotate in the opposite direction synchronously generate suction (vacuum degree) at the inlet, so as to inhale the materials to be transported. The two rotors divide the rotor chamber into several small spaces and operate in the order of a-b-c-d. At a, only one chamber was filled with medium; At position B, part of the medium is sealed in chamber B; When it comes to position C, the medium in chamber a is also sealed; When it reaches the D position, chambers a and B are connected with chamber 2, and the medium is transported to the discharge port. In this way, the medium (material) is continuously sent out.

Transmission of rotor pump: the transmission of rotor pump generally has the following forms

  1. Motor + constant speed ratio reducer: this transmission mode is simple, the speed of the rotor is constant, which determines the non adjustability of the flow. If equipped with frequency converter can achieve speed regulation.
  2. Motor + mechanical friction type continuously variable transmission: the speed change of this kind of transmission is realized by manual adjustment, which is characterized by safety, reliability and stepless flow adjustment. The disadvantage is non automatic regulation, more trouble, speed regulation in the process of operation, not in the state of shutdown speed regulation.
  3. Variable frequency motor + frequency converter: this way can realize the automatic adjustment of speed, that is, realize the stepless adjustment of flow. Its advantages are high degree of automation and convenient operation. The disadvantage is that the price of frequency converter is higher and the low speed torque is smaller.

Brief introduction of application scope of rotor pump

  1. Food and beverage: dairy products, latex, chocolate, syrup, cheese, malt juice, beer, soda, cream, concentrated juice, fermentation liquid;

  2. Fruit concentrate: pudding, jam, jelly, tomato sauce;

  3. Paste products: fat and grease, etc;

  4. Cosmetics: cream, detergent, hair gel, perfume oil and so on;

  5. Chemical industry: dyes, fats, solvents, resins and polymers;

  6. Drugs: extract, emulsion, pill pulp, etc;

Single blade rotor

This rotor is designed and manufactured to solve the problem of transporting large particles. Its unique shape and curve make it have the advantage over other pumps when transporting the large particle material, and can effectively avoid the damage of particles in the material during the transportation.


Double blade rotor

The rotor pump with this structure is often used in conveying materials or fillings containing particles, which can reduce the crushing rate. This kind of pump generally has better effect in the case of poor convective transport or particles in the materials.


Three blade rotor

The general rotor type has larger volume than other types, and its performance indexes are better than those of one blade and two blade rotors.


Multi blade rotor

When there are more than three rotor blades, the volume decreases with the increase of rotor blades. The more the rotor blades are, the less the volume is. The stability of multi blade rotor is relatively improved when conveying materials, but it is easy to break the granular materials in the process of conveying.


Butterfly rotor pump

Due to the use of butterfly rotor, it not only has the characteristics of general rotor pump, but also has certain advantages in conveying materials with high viscosity and large particles. It can effectively transport especially viscous materials
Single butterfly curve rotor pump (particle rotor pump)
This series of pumps are specially designed and manufactured to solve the problem of conveying materials containing large particles. Its unique shape and curve form make it have incomparable advantages when conveying materials containing large particles. In the process of conveying materials, it can effectively avoid particle damage and is the first choice of pumps for conveying materials containing particles


Note: the flow range in the table refers to the data measured when the medium is "water".
Stepless speed change machine or frequency converter is used for speed regulation, and its speed range is 200 ~ 900rpm.
When conveying high viscosity concentrated liquid, the motor power must be increased.
For the medium with poor fluidity, it is recommended to use the pump with matching flow at the inlet.
If there is any change in the data in this table, no further notice will be given. The correct parameters shall be subject to the material object provided.
