Chemical Pumps

Chemical pumps are made of corrosion-resistant materials to enable them to process commercial and industrial abrasives, chemicals and corrosive liquids. These types of pumps are commonly used to pump fuels and processing chemicals, but just as the word “chemical” is a very broad term, the uses for chemical pumps are very diverse as well.

Chemical centrifugal pumps are usually powered by an engine or an electric motor. Using an impeller, the pump converts the rotational energy from the motor to hydrodynamic energy. Chemical fluids enter the pump near the axis of the impeller and then accelerated radially outward. This acceleration can be attributed to the “centrifugal force” or the inertia of the fluid.

Once the fluids have been accelerated away from the impeller axis, they can enter a diffuser where they exit the pump. Chemical pumps are used for chemicals that are water-like in viscosity and when the quantities of flow are large compared to the pressure requirements.

When it comes to the need to pump adhesives, bleach, coatings, chromic acid, fuel, oil, paint, resin, salt water, solvent, etc. from a container to a transfer station or to the point of application, a chemical pumps are an excellent option. These chemical pumps can also come in several different varieties to overcome particular challenges of fluid transportation applications.

Because they need to be able to handle corrosive chemicals or solution process temperatures, chemical pumps are usually constructed from thermoplastics or metal.
