When it comes to buying a chemical pump, there are several application and pump requirements you will need to take into consideration.

In this blog, our team discuss the different specifications and information you will require. It’s important that prior to purchase, you speak to an expert, as if the incorrect pump is selected it could cause bodily harm, as well as environmental impact.

The materials used for the construction of the pump must be compatible with the chemical it will be pumping. Acids, such as sulphuric acid and hydrochloric acid are especially corrosive and could damage the internals of the pump.

There are two varieties of pumps:

Metal Pumps - these can be classified as ferrous or non-ferrous and are manufactured from stainless steel, a nickel alloy or titanium to protect from corrosion.

Non-metallic pumps - these are constructed from rubber (natural and synthetic), ceramics, special plastic such as polypropylene and PVDF. Non-metallic pumps are commonly used for corrosive materials.
