Overview of CDL Lightweight Vertical Multistage Centrifugal Pump Products

The CDL series lightweight vertical multi-stage centrifugal pump (hereinafter referred to as the pump) is a non self-priming vertical multi-stage centrifugal pump designed and manufactured by absorbing advanced technologies at home and abroad. It adopts standard vertical motors and quick installation mechanical seals, making replacement very convenient.

The overcurrent part of the pump is made of stainless steel (304 \ \ 316) material, which is suitable for mildly corrosive media. This product can replace similar foreign products such as CR and CRN. After the product was launched on the market, it was deeply loved by a large number of users due to its high efficiency, energy saving, reliable quality, and wide range of applications.

Product features of CDL lightweight vertical multi-stage centrifugal pump

1. By adopting excellent hydraulic models and advanced manufacturing processes, the performance and service life of the pump are greatly improved.

2. Due to the use of mechanical seals made of hard alloy and fluororubber, the reliability of pump operation and the temperature of the conveying medium can be improved.

3. The overcurrent part of the pump is made of stainless steel plate stamped and welded, making the pump suitable for mildly corrosive media.

4. The overall structure is compact, the volume is small, the weight is light, the noise is low, the energy-saving effect is significant, and the maintenance is convenient.

5. The inlet and outlet of the pump are located on the same horizontal line as the pump seat and can be directly used in the pipeline.

6. Using standard motors, users can easily equip motors according to their needs.

7. Intelligent protectors can be equipped according to user needs to effectively protect pumps from dry running, phase loss, overload, etc.

Installation condition requirements

1. Before installation, carefully check whether there are any hard objects inside the pump body to avoid damaging the impeller and pump body during operation.

2. During installation, pipeline management should not be added to the pump to prevent deformation and affect normal operation.

3. Tighten the anchor bolts to prevent vibration during start-up from affecting the performance of the pump.

4. Install regulating valves on the inlet and outlet pipelines of the pump, and install pressure gauges near the pump outlet to control the pump's operation within rated conditions and ensure its normal use.
