Sizing of chemical pumps

When selecting a pump for aggressive liquids, it is necessary to carefully analyze various data without uselessly over-sizing. This is the only way to avoid reduced performance or unwanted malfunction. Some of the data requested for the proper sizing of a chemical pump are as follows:

  • Characteristics of the liquid (chemical nature, composition, concentration, temperature, specific gravity).
  • Flow and pressure.
  • Possible characteristics of the hydraulic circuit (charge loss, ancillary plant equipment, specific needs).

The data analysis will provide the proper tools for selecting best material, suitable impeller, and correct motor power. Namely, the choice of the best pump for your needs.
