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.

More information on materials and other pumps features can be found on Engineering360's Pump Features page.

Related Products & Services

  • Dosing Pumps

    Dosing pumps are low-volume fluid pumps with controllable discharge rates used to inject additives into the mixing or pumping system.

  • Magnetic Drive Pumps

    Magnetic drive pumps are sealless pumps that use a coaxial magnetic coupling to transmit torque to an impeller. A standard electric motor drives a set of permanent magnets that are mounted on a carrier or drive assembly.

  • Plastic Pumps

    Plastic pumps are designed to move fluids that would corrode or damage other types of pumps. They provide broad chemical resistance and are less costly and lighter in weight than metal pumps.

  • Positive Displacement Pumps

    Positive displacement pumps use a mechanical force such as gears, bladders, pistons, plungers or diaphragms to push liquid through and out of the pump.

  • Progressing Cavity Pumps

    Progressing cavity pumps are a type of rotary positive displacement pump designed to transfer fluid or media with suspended solids or slurries from the suction side of the pump to the discharge side of the pump, from storage tanks or through pipelines. 

  • Sanitary Pumps

    Sanitary pumps are used to transport and meter solutions, slurries, and colloids of food and agricultural materials in operations such as food processing that require cleanliness. There are four basic types of sanitary pumps: centrifugal, positive displacement, jet, and airlift.

  • Syringe Pumps

    Infusion or withdrawal syringe pumps provide high pressure and high accuracy for applications such as high performance liquid chromatography (HPLC).  Used to deliver precise amounts of fluid at specific time intervals.
