CHM Light Horizontal Multistage Centrifugal Pump
Application
The CHM pump is mainly used in industry:
● Air conditioning system
● Cooling system
● Industrial cleaning
● Water treatment (purification of water)
● Aquaculture
● Fertilization/metering system
● Environmental applications
● (Other) Many specialized and specific uses
Conveying liquids
● A thin, clean, non flammable and explosive liquid that does not
contain solid particles or fibers.
The pump can transport materials such as mineral water, softened
water, pure water, clear oil, and other light chemical media.
When the density or viscosity of the conveyed liquid is greater
than that of water, a high-power motor must be equipped if
necessary.
The suitability of a pump for a specific liquid is determined by
multiple factors, including
The most important factors are chlorine content, pH value,
temperature, solvent, oil content, etc.
Operating conditions
Liquid temperature: room temperature type -15 ℃ to+70 ℃
Hot water type -15 ℃ to+105 ℃
Maximum ambient temperature:+40 ℃
Maximum operating pressure: 10 bar
Maximum inlet pressure is limited by maximum operating pressure
Curve conditions
The following conditions apply to the performance curve shown
later.
All curves are based on the measured values of a motor with a power
of 0.25kw at a constant speed of 2850rpm, and other motors with
power at a constant speed of 2900rpm.
The curve tolerance complies with ISO9906:2012.3B level.
The test uses water without air at 20 ℃, with a kinematic viscosity
of 1mm2/s.
The use of pumps should refer to the performance range of the bold
curve to prevent overheating caused by low flow rate and motor
overload caused by excessive flow rate.
Model Meaning
CHM Example
Motor
The motor is a fully enclosed, air-cooled two pole motor.
● Protection level: IP55
Insulation level: F
Standard voltage: 50Hz: 1x220-240V
3x220-240V/380-415V
The maximum power of a single-phase motor is 2.4kW.
Pump
Horizontal multi-stage non self priming centrifugal pump with
extended shaft motor.
The compact structure makes the pump size very small, with axial
inlet and radial outlet.
