What is a chemical pump?
A pump is designed specifically for use in pumping chemicals. In general, they should be resistant to corrosive materials, which makes it possible for them to handle corrosive and abrasive industrial liquids that would be damaging to standard pumps and piping systems. Apart from these general qualifications, these pumps may be practically any type of pump. Some are made to handle simple, less corrosive chemicals such as oils or cosmetic products, while others are designed to pump the types of dangerous and volatile chemicals that must be kept under very specific conditions.
If you need to pump solvents, salt water, oil, fuel, resin, paint, coatings, bleach, adhesives, acids, or any other type of chemical, it’s probably necessary to have a chemical pump that is specially equipped to handle the particular substance that you’re dealing with.
Since they can be used in a wide variety of applications, both centrifugal and positive displacement pumps can be used. The most common centrifugal type is the ANSI B73.1 pump, which is an end suction, single stage centrifugal pump. Many are positive displacement pumps such as pistons pumps, diaphragm pumps, screw pumps, or plunger pumps. These pumps are used to move liquid chemicals at high pressures. For thicker chemicals or those with high viscosity, very heavy-duty pumps are needed.
