Stainless Steel Vertical Multistage Centrifugal Water Pump

CDM/CDMF Light Vertical Multistage Centrifugal Pump

Model definition

Summary

CDM/CDMF pumps are new generation, high efficiency, non-self-priming vertical multistage centrifugal pumps (Abbr. as pumps). It referred European standard, used entirely new industrial design. It is energy saving, low noise, environment friendly, compact design, beautiful shape, light, easy for service, high reliability.

3×220-240/380-415V

Working conditions

Thin, clean, non-flammable, non-explosive, solid free, fiber free, physically and chemically water-like liquid.

Liquid temperature:

Normal temperature type: -15℃ to 70℃

Hot water type:-15℃ to 120℃

Ambient temperature: up to +40℃

Altitude: up to 1000m

Application

CDM/CDMF pumps are designed for a variety of applications from the pumping of potable water to the pumping of industrial liquids. Applied for liquids of different temperature, different rated flow, different pressure range. CDM is suitable for non-corrosive liquid, CDMF is suitable for light corrosive liquid.

Boosting: Filtering and transferring water in water factories, delivering water in different zone, pressuring for major pipelines, boosting for high buildings.

Pressuring: Water circulating system, washing system, high pressure flushing system, fire-fighting system.

HVAC: Air condition system

Water treatment: Ultrafiltration system, R/O system, distillation system, separator, swimming pool.

Performance curve

Following conditions are suitable for performance curve below.

1.All curves are based on the measured values of 50Hz;constant motor speed 2900rpm or 2950rpm.

2.Curve tolerance in conformity with ISO9906:2012, Grade 3B.

3.Measurement is done with 20℃ air-free water, kinematic viscosity of 1mm2 /sec.

4.The operation of pump shall refer to the performance region indicated by the thickened curve to prevent overheating due to too small flow rate or overload of motor due to too large flow rate.

Product Description

Convey liquid

Thin, clean, non-flammable and non-explosive liquid without grain or fiber.
Pump can convey mineral water, softened water, pure water.
In case density of the liquid conveyed by the pump is higher than that of water, it is necessary to use corresponding motor of higher output power.
The application of the pump is decided by many factors.The most important factors are chlorinity, PH value, temperature, solvent, oil content etc.
