HORIZONTAL MULTI-STAGE CENTRIFUGAL PUMP

 

CHL

CHLF


 


 

CHL, CHLF SERIES

CHL and CHLF are non-self-priming light horizontal multi-stage centrifugal pumps. They are efficient, low-noise, have little corrosive tolerance, compact structure, good looking, small volume, light weight, etc.

Motor

  • TEFC motor 2-pole

  • Protection class: IP55

  • Insulation class: F

  • Standard voltage: 60Hz:

1 x 220-240V
3 x 220-240V / 380-415V

  • Single phase motor (max): 2.4kW                                       

Operation condition

  • Liquid temperature:
         Normal temperature type: -15°C ~ +70°C
         Hot water type: -15°C ~ +105°C

  • Ambient temperature: up to +40°C

  • Max. operation pressure: 10bar

  • Max. inlet pressure is limited by max. operation pressure

Application

CHL and CHLF type pumps are mainly sued in the industrial field:

  • Water treatment (Water purification)

  • Cooling system

  • Industrial cleaning

  • Air-conditioning system

  • Aquaculture

  • Fertilizing/metering system

  • Environmental application

  • Other special application

Application medium

  • Thin and clean non-flammable and non-explosive liquid without solid granules and fibers.

  • Mineral water, soft water, pure water, edible vegetable oil, and other light chemical mediums.

  • When the density or viscosity of the to-be-conveyed liquid is larger than that of water, it is necessary to select a driving motor of high power.

  • Whether a specific liquid is suitable for the pump depends on many factors, among which the most important ones are chlorine content, pH value, temperature, solvent, and oil content.

Curve conditions

The following conditions are suitable for the performance curve shown:

  • All curves are based on the measured values of 60Hz: Constant motor speed 3500 r/min.

  • Curve tolerance in conformity with ISO9906.

  • Measurement is done with 20°C air-free water, a kinematic viscosity of 1mm²/sec.

  • The operation of the pump shall refer to the performance region described by the thickened curve to prevent

  • overheating due to too low a flow rate or overload of the motor due to a high flow rate.
