What Are Chemical Pumps?


Equipment plays an important role when it comes to the success of manufacturing businesses. But the kind of equipment used dramatically differs depending on the processes and products involved.

This as well applies to chemical processing businesses. According to experts at Pumpbiz, the chemical pumps the industry uses should guarantee safety, efficiency, and versatility.

What a Chemical Pump Is

Well, these are pumps used to carry chemicals. They are made to withstand abrasive and corrosive industrial liquids, like solvents, bleach, paint, and fuel, you name it.

A chemical pump can either be a positive displacement pump or a centrifugal pump, based on specific applications.

One of the common chemical centrifugal pumps is the ANSI pump. According to pump experts, these are single-staged suction pumps.

Most chemical pumps are as well positive displacement systems, like AODD, double-diaphragm, plunger, and screw pumps. All these are used to move a liquid chemical at high pressure.

Parts of Chemical Pumps

Whether chemical pumping is required for industrial wastewater or feed pumps to supply municipal water, chemical pumps have certain components.

Especially dosing chemical pumps are small as well as powered by what is called air actuator or motor. Some of the components found in dosing chemical pumps are:

  • Dosing line
  • Injector
  • Foot valve
  • Feed pump
  • Control system
  • Container or tank


Other pumps are found in the chemical processing industry besides centrifugal and positive displacement pumps. These include turbine pumps and diaphragm pumps.

Turbine pumps come with a turbine-like impeller, which is radially oriented so as to move fluid. They also combine the versatility of centrifugal pumps with a high discharge pressure of a positive displacement pump. But they are not ideal for transporting a liquid with solid elements.

On the other hand, diaphragm pumps can be said to be a kind of positive displacement pump. They move gas-liquid mixtures or liquids through what is called a reciprocating diaphragm. But they have more advantages than other kinds of positive displacement pumps. Diaphragm pumps are not just available in metal. They are also available in plastic.

Choosing Chemical Pumps

The material used to make the base of chemical pumps is vital to look at. That is because it dictates the kind of media, which may be handled comfortably or effectively.

System fluids can be caustic, cold, acidic, abrasive, or hot. A base material, like plastic, stainless steel, and cast iron, comes with several benefits for dealing with chemical components.


A centrifugal pump is helpful in numerous applications, from unloading and storage to circulation and filtration. Because of being harsh in nature, abrasive and corrosive chemicals should be dealt with carefully.

As manufacturers and designers establish pumps, they will need to choose pumps, which are made to withstand a specific corrosive chemical involved in the entire process.

Final Touches!

Chemical pumps are required when the fluid you want to transfer can’t be used with regular pumps. Mostly, they are used when chemical components to be transported are either abrasive or corrosive. Whether you want to transfer sodium hypochlorite, acetic acid, or sulfuric acid, you can use a chemical pump for the job.
