Application

The vertical multi-stage pump is a multi-functional product, which can transport all kinds of media from tap water to industrial liquid and adapt to different temperature, flow and pressure ranges. CDL is suitable for non corrosive liquid and CDLF is suitable for mild corrosive liquid.

●Water supply: water filtering and transportation, water supply division, main pressurization, high-rise building pressurization.

●Industrial pressurization: process water system, cleaning system, high pressure flushing system, fire fighting system.

●Industrial liquid transportation: cooling and air conditioning system, boiler water supply and condensation system, machine tool matching, acid and alkali.

●Water treatment: ultrafiltration system, reverse osmosis system, distillation system, separator, swimming pool.

●Irrigation: farmland irrigation, sprinkler irrigation, drip irrigation.

Operating conditions

●Thin, clean, non flammable and non explosive liquid without solid particles or fibers.

●Liquid temperature: normal temperature - 15C to + 70 ° C hot water type-15 ° C to + 120c

●Ambient temperature: max. + 40C           

●Altitude: up to 1000M

Pump

KDL / kdlf is a non self-priming vertical multistage centrifugal pump installed with standard motor. The motor shaft is directly connected with the pump shaft through the pump head with a coupling. The pressure cylinder and flow passage parts are fixed between the pump head and the water inlet and outlet section by pull rod bolts, and the water inlet and outlet of the pump are on the same straight line at the pump bottom; The pump can be equipped with intelligent protector to effectively protect the pump from dry running, phase loss and overload.

Electric machinery

●The motor is totally enclosed, air-cooled two pole standard motor.

●Protection level: IP55

●Insulation class: F

●Standard voltage: 

50Hz: 1 x 220-230/ 240V   3 x 200-220/ 346-380V   3 x 220-240/ 380-415V

3x 380-415V

Performance curve

The following instructions apply to the curves shown later:

1. All curves are based on motor measurements at constant speed of 2900 rpm or 2950 rpm.

2. The curve tolerance is in accordance with iso9906, Appendix A.

3. The test was carried out with 20 samples ° C water without air, the kinematic viscosity is 1mm2 / s

4. The use of the pump refers to the performance range of the bold curve, so as to prevent overheating caused by too small flow and motor overload caused by too much flow.
