CDL/CDLF is akind of multifuntional products. It can be used to convery various medium from tap water to industrial liquid at different temperature and with different flow and pressure. CDL type is applicable to cnveying non-corrosive liquid, while CDLF is suitable for slighty corrosive liquid.

  • Water supply : Water filter and transports in waterworks, boosting of main pipeline, boosting in high-rise buildings
  • Industrial boosting : Process flow water system, cleaning syste, 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
    – Normal temperature type : -15°C-+70°C
    – Hot water type : +70°C-+120°C

CDL/CDLF is akind of vertical non-self priming multistage sentrifugal 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 and intelligent protector to effectively it from dry-running, out of-phase and overload.

Electric motor

  • Full-enclose air-blast two-pole standard motor
  • Protection class IP55
  • Insulation class F
  • Standard voltage, 50 Hz
