  • Cooling towers and CIP/SIP
  • Desalination, biofuel systems, leach mining
  • Boiler and heating systems
  • Wash and clean, bottle washing, painting lines, and more

How to size a Grundfos Dosing Pump:

  1. Max required dose rate in L/h and minimum required dose rate in L/h
  2. Maximum system head pressure at injection point in bar
  3. Chemical technical ingredient and concentration %
  4. Available power supply (volts, phase)
  5. Pump control method as per chart below
