Safe Transfer of Hazardous Fluids with Corrosive Fluid Pumps

If you’re handling corrosive fluids such as acids and caustic solutions, you will know that their hazardous nature which can damage other substances they come into contact with can pose certain challenges. As a supplier of corrosive liquid pumps for over 15 years, we know how critical material selection is to prevent corrosion, leaking and the downtime to your process caused by consequential pump failure. Due to the potential hazard acids and caustics pose to humans, another of our considerations when specifying your corrosive liquid transfer pumps is limiting the chance of leakage of fluid. Castle Pumps’ offering therefore includes seal-less options that are less prone to wear and leaks, such as magnetic drive pumps and peristaltic pumps. Therefore, whether you require a highly accurate dosing pump, a barrel emptying pump or one for tank to tank transfer, Castle Pumps have a tried and tested solution for your potentially hazardous fluid. Upon full disclosure of the fluid or an MSDS sheet, our pump experts will provide a competitive quotation on the model they specify as most suited.

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.
