The CDLF light multi-stage pipeline centrifugal pump is a non-self-priming vertical multi-stage centrifugal pump designed and manufactured by adopting new technologies. It uses a standard vertical motor and quick-install mechanical seals, making replacement very convenient. The pump's flow parts are all made of stainless steel (304/316) material, suitable for mildly corrosive media. This product can replace similar products such as CR and CRN. After being introduced to the market, it has been widely favored by users for its energy efficiency, reliable quality, and broad application range.

Product Features

1. The use of an excellent hydraulic model and high-level manufacturing technology greatly improves the pump's performance and service life.

2. Since the shaft seal uses mechanical seals made of hard alloy and fluorine rubber, the reliability of pump operation and the temperature of the conveyed medium can be enhanced.

3. The pump's flow parts are made by stamping and welding stainless steel plates, allowing the pump to be suitable for mildly corrosive media.

4. Compact overall structure, small size, light weight, low noise, significant energy-saving effect, and convenient maintenance.

5. The pump's inlet and outlet are located on the same horizontal line of the pump base, allowing direct use in pipelines.

6. The use of a standard motor allows users to easily configure the motor according to their needs.

7. An intelligent protector can be equipped as per user requirements to provide effective protection against dry running, phase loss, and overload.
