CHLF(T) performance curves

Typical applications

  • Air-conditioning and cooling-water circulation
  • Industrial cleaning and washing systems
  • Water treatment and purification
  • Aquaculture and environmental systems
  • Fertilization and metering-support systems
  • Clean-water pressure boosting and process transfer

Selection and ordering guide

  • Provide required flow and total dynamic head, including pipe and fitting losses.
  • Confirm liquid composition, pH, chloride content, temperature, density and viscosity.
  • Confirm normal or hot-water version, stainless grade and CHLF or CHLF(T) inlet/outlet construction.
  • Confirm voltage, frequency, phase, connection standard and control method.
  • Review NPSH available, inlet pressure and the 10 bar maximum working-pressure limit.

Installation and maintenance

Install the pump horizontally on a rigid level base, align piping without strain, provide isolation valves and avoid dry running. Prime the pump before start-up, verify motor rotation, and monitor noise, vibration, leakage, pressure and current. Isolate electrical power and system pressure before servicing seals, bearings or hydraulic stages.
