CNP Pump CDL, CDLF is a kind of multifunctional products. It can be used to convey various medium from tap water to industrial liquid at different  temperature and with different flow rate and pressure. CDL type is applicable to conveying non corrosive liquid, while CDLF is suitable for slight corrosive liquid.

  • Water supply Water filter and transport in Waterworks, boosting of main pipeline, boosting in high rise buildings.
  • Industrial boosting: Process flow water system, cleaning system, high pressure washing system, fire fighting system.
  • Industrial liquid conveying: Cooling and air conditioning system, boiler water supply and condensing system, machine associated purpose, acids and alkali.
  • Water treatment: Ultrafiltration system, reverse osmosis system, distillation system, separator, swimming pool.
  • Irrigation: Farmland irrigation, spray irrigation, dripping irrigation.

Operation conditions

  • Thin, clean, non-flammable and non-explosive liquid containing no solid granules and fibers.
  • Liquid temperature:
  1. Normal temperature type: -150C – +700C
  2. Hot water type: +700C – +1200C

CDL/CDLF is a kind of vertical non self priming multistage centrifugal pump, which 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 pump head and in-and outlet section with tie-bar 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 overload.


Electric motor
