Pumps for the safe transfer of acids and caustic solutions

Corrosive fluids are typically categorised as hazardous liquids that damage and destroy other substances when they come into contact with them, typically acids and caustic solutions. As a supplier of corrosive liquid pumps for over 15 years, we know how critical material selection is to prevent corrosion, leaking and pump failure. Due to the potential hazard acids and caustics pose to humans, another requirement of corrosive liquid transfer pumps is a limited chance of leakage of fluid. Castle Pumps’ offering, therefore, includes seal-less options for this very reason.

To make sure that the corrosive fluid pump we select will offer you a long, trouble-free service life, we will ask for full liquid disclosure or an MSDS sheet so that thorough consideration can be given to the materials.

FAQs

This depends upon material compatibility with the specific chemical, the installation type and whether the chemical is clean or contains solids. However, peristaltic, AODD and magnetic drive pumps are popular chemical industry pumps thanks to their seal-less design, as are chemical barrel pumps due to how such fluids are generally stored.

A chemical dosing pump, otherwise known as a chemical metering pump, is designed to very precisely deliver a specific quantity of a chemical to a container, tank or fluid stream at controlled intervals. They are particularly popular in the water treatment industry.

We would need to cross check compatibility of the materials of all chemicals you wish to pump, but it is possible. If you are pumping multiple different liquids or where cross contamination is not desirable we suggest using the F310 or F430 chemical drum pumps.

Thanks to their accuracy at low flow rates, peristaltic pumps, diaphragm pumps and lobe pumps are most commonly used in chemical dosing systems.

Yes this is absolutely something to consider for chemical transfer pumps! A material’s resistance to a chemical can change depending on the concentration of the chemical and the temperature. For example, Hastelloy C is compatible with Sulphuric Acid at 98% concentration and up to 60°C, but at 80% Hastelloy C is only compatible up to 20°C.
