CDLF LIGHT STAINLESS STEEL VERTICAL MULTI-STAGE CENTRIFUGAL PUMP

Pump:

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 inlet and 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 overload.

Motor:

Full-enclosed air blast two pole standard motor

Protection class: IP55

Insulation class: F

Standard voltage: 50Hz: 1×220-230/240V

Performance scope:

Product range:

Operation conditions:

Thin, clean, non-flammable and non explosive liquid containing no solid granules and fibers.

Liquid temperature:

Normal temperature type: -15℃ ~ +70℃,

Hot water type: -15℃ ~ +120℃

Ambient temperature: up to +40℃

Altitude: up to 1000m

Application:

CDLF is a kind of multinational 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. CDLF is suitable for slightly corrosive liquid.

Water supply: Water filter and transport in Water works, 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: Ultra-filtration system, reverse osmosis system, distillation system, separator, swimming pool.

Irrigation: Farmland irrigation, spray irrigation, dripping irrigation.

Max.Working pressure:

Max.Ambient temperature:

When the pump operates under ambient temperature higher than 40℃ or under altitude higher than 1000m, because of low air density and poor cooling effects, the motor output power P2 will be decreased to certain extent. If the pum is operated under the above said conditions, it should be equipped with motor of higher power.

Minimum inlet pressure NPSH:

In case that the pressure in pump is lower than the steam pressure used to convey liquid, the cavitations will occur. To avoid cavitations, a minimum pressure at the inlet side of the pump shall be guaranteed.

Check and ensure that the pump is not at cavitations state.

Operation in parallel:

Connecting several pumps in parallel running will benefit much more than running a single large pump.

    Applicable to different working states necessary in a variable flow system.

    lncreasing the possibility of water supply when the pump is in failure. Because in case of pump failure, only part of the system flow is effected.
