Kweng Sealless Magnetic Drive Pumps—Multistage are a modular range of chemical service centrifugal pumps, ideal for high-pressure applications.
The design of these pumps incorporates integrated diffusers and stage casings. The impellers are arranged in series on a single extended shaft assembled with a synchronous permanent magnetic drive, making it a sealless magnetic drive pump—multistage.
By maximizing component interchangeability, we design the pumps to cover a wide duty and application base using the minimum number of pump models.
Kweng Sealless Magnetic Drive Pumps – Multistage are categorized into:
CSP—M: The CSP—M Series sealless magnetic drive pumps—multistage—are designed to cater to chemical processing, hydrocarbon processing, etc., with high head requirements.
Customized materials (e.g., carbon, TC, etc.) on demand;
Applications:
This group of pumps is usually used in places where high flows are needed, like in industries that deal with acids, lye, hydrocarbons, hot water, heat transfer liquids, liquid petroleum gases (LPG), dangerous, explosive, and toxic liquids, liquids that contain solids, refineries, liquid gas plants, power plants, and more.
