Multistage Centrifugal Pump

DL series vertical multistage centrifugal pump based on the needed for water supply and Fire-fighting special for high Building. With 4 pole motor,low speed,slight noise,high efficient and longevity advantages.

Water input/output:0o~90o      -180o     -270o

Flow:6.2~300m3/h

Head:24~225m

DN40~200mm

Applications:
CDL / CDLF are multifunctional product, which 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 convey non-corrosive liquid, while CDLF is suitable for conveying slightly corrosive liquid.
Features:
1) Water supply: water filter and transport in waterworks, boosting of main pipeline,
   boosting in high-rise buildings
2) Industrial boosting: process flow water system, cleaning system, high-pressure
   washing system, fire fighting system
3) Industrial liquid conveying: cooling and air-conditioning system, boiler water supply
   and condensing system, machine-associated purpose, acids and alkali
4) Water treatment: ultra filtration system, reverse osmosis system, distillation
   system, separator, swimming pool
5) Irrigation: farmland irrigation, spray irrigation, dripping irrigation
6) Operation conditions: thin, clean, non-flammable and non-explosive liquid,
   containing no solid granules and fibers
8) Altitude: up to 1,000m
Pump:
CDL / CDLF are vertical non-self priming multistage centrifugal pumps, which are 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 the inlet-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.
Structural characteristics:
1) Electric motor: full-enclosed air-blast two-pole standard motor
2) Protection class: IP55
3) Insulation class: F
4) Standard voltage: 50Hz
