What is a progressive cavity pump?
The progressive cavity pump is a special positive pressure pump widely used in various industrial fields. It consists of a spiral rotor and a matching stator, forming a series of sealed chambers between the two. When the rotor rotates, these chambers move slowly, resulting in a continuous flow.
Compared with traditional centrifugal pumps, progressive cavity pumps have several advantages:
High suction, capable of conveying high viscosity or particulate liquids.
Precise flow control, can accurately adjust the delivery volume.
Low pulsation, smoother delivery.
Corrosion-resistant, suitable for various chemical media.
Strong self-priming performance, no additional suction device is required.
In general, progressive cavity pumps are widely used in petrochemical, pharmaceutical, food processing and other industries due to their excellent performance. Whether it is conveying viscous materials or precise metering, it can do it. With the development of industry, this type of pump will play an increasingly important role.
