Vertical pumps for corrosive liquids

The chemical resistant construction features of our plastic pumps eliminate any contact of metal parts with aggressive fluids and ensure full chemical resistance to most corrosive products. With Savino Barbera vertical centrifugal pumps there is no need of openings at the tank bottom: the pumping of acids is safely performed.

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. That is, the choice of the best pump for your needs.
