What is a chemical dosing pump?

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.

What types of pumps are used for chemical dosing?

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

Does concentration of my chemical matter for pump selection?

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.

Can I get a chemical pump for use with multiple chemicals?

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.

Chemical Pumps for the Transfer & Dosing of Aggressive…

Chemical transfer & dosing pumps for aggressive fluids

As a supplier of chemical pumps for well over 15 years, we know that getting the right solution for your chemical process is absolutely vital. A pump that is incompatible with your chemical can result in swelling, dissolving or brittleness, and ultimately it leaking and failing. This is why special consideration needs to be given to the materials of a chemical transfer pump, along with the temperature and concentration of the fluid being handled. Whether you require a chemical dosing pump, a barrel emptying pump or one for tank to tank transfer, Castle Pumps have a tried and tested solution for your chemical process.

To make sure that the chemical transfer pump we select will offer you a long, trouble-free service life, we will ask for full fluid 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.
