Working principle of three bladed rotor pump

The working principle of is based on the suction force (vacuum degree) generated by two synchronously rotating rotors in opposite directions during the rotation process, thereby sucking in the material to be conveyed. This type of pump sucks in material from the inlet through the movement of the rotor, divides it into several small spaces through the rotor chamber, and then operates in a specific order to continuously deliver the medium (material) to the outlet. Specifically:

When the rotor reaches position a, only one chamber is filled with medium.

When reaching position b, a portion of the medium was enclosed in another chamber.

When reaching position c, all rooms are sealed with the medium.

Finally, when reaching position d, the enclosed chamber is connected to another chamber, and the medium is transported to the discharge port.

This cyclic motion enables the medium (material) to be continuously transported out. The three blade rotor pump is particularly suitable for conveying media that are easy to form foam and have high viscosity, concentration and particles, while maintaining the original quality of materials, without any physical and chemical reaction, and can control the flow more accurately, and even can be used as a metering pump
