The open impeller includes pump body, pump back cover installed at the opening end of the pump body, motor, and impeller arranged in the pump. The impeller is mounted on the pump shaft, it is driven by the motor, and the pump body is equipped with water inlet and outlet pipe. The process of stamping is convenient, the flow channel is free, and the hydraulic efficiency, strength and steel degree of the pump is improved.

The open impeller has no cover on both sides of the blade. It is easy to make and clean. It is suitable for conveying materials containing a large amount of suspended material, which is low in efficiency and low in liquid pressure. The general delivery pump is more of this type.

The advantages of open impeller centrifugal pump:
1. High corrosion resistance and high abrasion resistance, it is suitable for conveying sewage, mud, and liquid with certain corrosive liquid, such as sludge and sand.
2. Compact structure, no vibration, low noise, stable and reliable operation.
3. High-quality mechanical seal, no leakage, long service life.
4. The open impeller can handle sewage and liquid with fine debris.
5. Easy to maintain: open the front pump shell, we can check and maintain the pump shell directly. It is easy to replace wear disc.
6. Open impeller allows for large diameter particle objects.

Application of open impeller centrifugal pump:
It is applicable to the suspended solids in the process of conveying food, such as cleaning vegetables, meat, and fish food. Industrial cleaning machines containing solid particles, such as bottles, cans, glassware, and boxes. A process flow between paint and general dirty liquid.
