CDL/CDLF Vertical Multistage Pump

Denor CDL/CDLF vertical multistage centrifugal pump achieves high head by connecting multi-stage impellers in series, which is suitable for scenarios with high liquid pressure requirements. Common fields include secondary water supply for high-rise residential and office buildings, solving the problem of insufficient floor water pressure and ensuring stable water pressure.

The CDL/CDLF vertical multistage pumps are designed for a variety of applications from the pumping of potable water to the pumping of industrial liquids. Applied for liquids at different temperature, different rated flow, different pressure range.
CDL is suitable for non-corrosive liquid.
CDLF is suitable for slightly corrosive liquid.

Denor CDL/CDLF pumps adopts a new type of sealing technology to easily dismantle the stainless steel casing mechanical seal. What's more, this machine is driven by a standard electric motor. The motor output shaft directly connects with the pump shaft through a coupling. The pressure-resistant cylinder and flow passage components are fixed between the pump head and inlet & outlet section with stay bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overloading.

In summary, Denor CDL/CDLF vertical multi-stage centrifugal pump provides a powerful and efficient solution for water transportation and circulation. Its high voltage performance, compact design, and reliable performance make it the preferred choice for industrial, commercial, and residential applications.  It is an ideal choice for high-rise water supply, industrial high-pressure processes, and energy systems.

Feature:

1. It adopts an excellent hydraulic model and advanced manufacturing technology, which greatly improves the performance and service life of the pump.
2. This machine uses mechanical seals made of cemented carbide and fluorine rubber for the shaft seal, which can improve the reliability of pump operation and the temperature of the conveying medium.
3. The overflow part of the machine is made of stainless steel plate stamping and welding, making the pump suitable for mildly corrosive media.
4. With compact structure, small size, light weight, low noise, significant energy saving effect, and convenient maintenance.
5. The water inlet and outlet of the CDL/CDLF centrifugal pump are located on the same horizontal line of the pump seat, which can be directly used in the pipeline.
6. This machine utilizes standard motor, and users can easily equip the motor according to their needs.
7. Intelligent protectors can be equipped according to user needs to effectively protect the pump from dry running, lack of phase, and overload.
