The CDLF light-duty multistage centrifugal pump is a non-self-priming vertical multistage centrifugal pump designed and manufactured by adopting new technologies. It uses a standard vertical motor and a quick-install mechanical seal, making replacement very convenient.

The pump's flow parts are all made of stainless steel (304/316) material, making it suitable for mildly corrosive media. This product can replace similar products such as CR and CRN. Since its introduction 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 processes significantly improves the pump's performance and service life.

2. The mechanical seal, made of hard alloy and fluorine rubber, enhances the pump's operational reliability and the temperature of the conveyed medium.

3. The pump's flow parts are made of stamped and welded stainless steel plates, allowing it to handle mildly corrosive media.

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

5. The pump's inlet and outlet are located on the same horizontal line of the pump base, enabling direct installation 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.
