{Impeller (also known as working wheel) is the main part of the pump, and even the core part of the pump. Centrifugal system is based on the high-speed rotating impeller water to achieve energy calibration.Electrical Expansion Valve with coil DPF3.0C08 EXV
The wheel-glue of screw pump is composed of two circular cover plates. Between the cover plates, there are as follows: 1. The curved blades connect the front and rear cover plates together. The space groove enclosed by the two adjacent blades and the front and rear cover plates is commonly called water flow.

The shape and size of impeller are determined by experiment and calculation. Generally, it can be divided into leather suction impeller and double suction impeller. The front cover plate of the impeller has a round hole intake called single suction impeller. The front and rear cover plates of the impeller have a round 7L intake called double suction impeller.CBB Type Mini Electric Hydraulic Grease Gear Pump
The suction impeller has n-inlet water absorption on the cover plate of the biting wheel on the side of the bill of lading, but not on the back cover plate. The cover plate and the back cover plate of the wheel are H; they are symmetrical in shape. It is a double suction impeller. The front and rear cover plates of the impeller are all provided with circular intakes. The front and rear cover plates are symmetrical in shape. Generally, they are used in large flow centrifugal pumps.Emulsification Pump Laboratory Pump Inline Homogenizer Pump
When selecting the material of diaphragm pump, we should consider not only the enough mechanical strength, but also the wear resistance and corrosion resistance of the material. Nowadays, most impellers are made of cast iron, cast steel and bronze. Hard plastics and alloy steel are also used to some extent.
