The progressive cavity pump is a widely used type of pump in industrial and engineering applications, known for its unique design and superior performance. Allweiler is a reputable brand in this field, offering high-quality progressive cavity pumps suitable for various operating conditions.
Working Principle of Progressive Cavity Pumps
The working principle of a progressive cavity pump is primarily based on a helical rotor rotating within a fixed stator. The rotation of the rotor compresses the fluid gradually within the cavity and discharges it. The working process can be summarized in the following steps:
- Suction Stage: As the rotor rotates, fluid is drawn into the cavity from the inlet.
- Compression Stage: With further rotation of the rotor, the fluid is progressively compressed, and pressure increases.
- Discharge Stage: The fluid is finally expelled from the outlet, completing the cycle.
