Chemical Pumps Information

Chemical pump from All-Flo Pump Company, LLC

Chemical pumps are designed to move and withstand chemicals and chemical slurries. They are designed and constructed to handle substances with varying levels of viscosity, corrosiveness, and abrasiveness. Some of these pumps are also metering pumps, which provide flow measurement and control for applications which require precise volumes of chemicals.

Pump Types

The first step in selecting a chemical pump is determining the most suitable type of pump for the application. Nearly all types of pumps can be designed as chemical pumps, so there are many to distinguish between. For a complete overview of different pump types and classifications, visit the Pump Types page on Engineering360.


The next step to sourcing a chemical pump is determining the performance specifications required. The primary specifications to consider include:

  • Flowrate
  • Head
  • Pressure
  • Horsepower
  • Operating temperature

A complete guide to pump specifications and performance can be found at Engineering360's Pump Flow page.


Chemical pump from Gorman-Rupp IndustriesThe base material of a chemical pump is important to consider, as it affects the type of media that can be handled effectively. System fluids may be abrasive, acidic, caustic, tacky, very hot, very cold, or otherwise hazardous. Base materials such as cast iron, plastic, and stainless steel possess different advantages for handling these various characteristics.

  • Plastics and thermoplastics may be the least expensive base materials, and provide excellent corrosion resistance from acids and various chemicals.
  • Stainless steel alloys provide protection against chemical and rust corrosion, and have higher pressure ratings than most plastics.
  • Cast iron provides excellent strength and abrasion resistance, with high pressure ratings.
