Corrosive Liquid Pumps

Need some advice? Our technical sales engineers are always on hand!

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.

Past corrosive liquid pump project

Castle Pumps have been specifying corrosive resistant caustic and acid pumps for over 15 years, meaning that we have a problem solved an application just like yours before.

In this case, study, read how we supplied a UK chemical producer with a peristaltic pump for efficiently handling the transfer of Aluminium Sulphate with 2-3% solid content within their production process. The beauty of the pump design is that only the inner tube needs to be compatible with the solution in question.

The importance of chemical compatibility

Ever wondered why you couldn’t just have a pump that is suitable for all fluids? This is where chemical compatibility comes into play. The actual impact of chemical compatibility depends on how resistant the material is to the medium it comes into contact with. Therefore, should a pump be pumping a liquid that is incompatible with the material that it is constructed of, a problem arises

Want to find more information about the effects of chemical incompatibility and how to select a pump that is compatible with your fluid? Read our article and learn everything you need to know about chemical compatibility.
