Sizing a dosing pump involves several steps: First, determine the flow rate and pressure requirements of your application. Calculate the chemical concentration needed and convert this into a dosing rate, usually in liters per hour (LPH) or gallons per hour (GPH). Then, consider any viscosity and temperature variables that could affect pump performance. Finally, select a pump with a capacity range that meets your requirements, ensuring a margin for error to accommodate any fluctuations in demand.

FAQs & Answers

  1. What factors should I consider when sizing a dosing pump? You should consider flow rate, pressure requirements, chemical concentration, viscosity, temperature, and ensure the pump capacity allows for demand fluctuations.
  2. How do I calculate the dosing rate for a pump? Calculate the required chemical concentration and convert it into a dosing rate, typically expressed in liters per hour (LPH) or gallons per hour (GPH).
  3. Why is it important to allow a margin of error when sizing a dosing pump? Allowing a margin of error ensures the pump can handle fluctuations in demand and variations in application conditions without performance loss.
