As you might expect, chemical pumps are designed to handle fluids that are corrosive or abrasive. While the term chemical pump is specific, the applications for using chemical pumps are more widespread than the term might imply.

Uses for chemical pumps

Transferring liquids that can harm regular pumps covers a broad set of applications. While we will list some of these pump applications to illustrate the breadth of use, please be sure to consult with our PumpBiz engineers for specific pumps or application requirements. Some chemical pump applications include:

Fuel Pumps

Liquid fuels can be very corrosive. In addition to meeting the needs for a chemical application, you should also discuss explosion proof pumps with our engineers. There are specific standards required for fuel pumps, so be sure you have all the specifications nailed down before purchasing or installing a new pump.

Acid Transfer Pumps

Sulphuric acids, acetic acid, and similar liquids present unique engineering and safety challenge.

Pumps for Solvents/Cleaners

By their very nature, these liquids are design to “eat away” and materials in which they come into contact. Solid chemical pumps are a must in any application transferring these liquids.

ANSI Pumps

American National Standards Institute (ANSI) created a set of standards so that pumps can be replaced while being confident the new pump will operate properly with existing equipment. By manufacturing chemical pumps that follow the ANSI standards, pump manufacturers’ equipment will be interchangeable. This gives you the flexibility to find the best value for your pump application while ensuring the integrity of your system.

The ANSI standards are set by 3 classes, or groups, based on pump size. This will ensure compatibility with couplings, motor connections, bedplates, and other piping.

  • Group I: ANSI process pump sizes from 1.5 by 1-6 to 3.0 by 1.5-8.
  • Group II: ANSI process pump sizes from 3 by 2-8 to 6 by 4-13.
  • Group III: ANSI process pump sizes from 6 by 4-16 to 10 by 8-17.

While the ANSI standards can ensure compatibility within a system, they are not a guarantee that the pumps are appropriate for a given application. If you are not confident that the chemical pump is right for the application, please contact us to discuss your project specs.
