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.
Motor
Totally enclosed, fan cooled, 2 pole standard motor
IP class: IP55
Insulation class: F
Voltage: 50Hz:1×200-230/240V
3×200-220/346-380V
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
