Chemical Pumps


Transporting or conveying chemicals and other chemical products with aggressive, acidic or otherwise challenging properties places special demands on the know-how of chemical pumps and the materials used. Depending on the substance and type of application, a variety of pumps can be employed for the chemical industry.
These can be secondary circuits and applications without direct contact with the chemical medium, as well as applications for direct conveying of chemicals. Specially developed and resistant plastic centrifugal pumps and displacement pumps are available for this purpose.

The right chemical pump for every purpose

Chemical pumps are used for unloading raw materials, their preparation, in processing and in transformation processes up to the storage and in many other areas, such as wastewater treatment. The decision on which pump is used in the end depends chiefly on the chemical properties of the pumped medium and the operational safety aspects.
Further details about the technical features and the possible application areas is located on the detail pages of the respective pump technologies. The chemical pumps manufactured by our members are suitable for all types of applications with and without direct contact with the chemical.

White paper

Selecting the right pump for chemical applications can turn into a search for the needle in the haystack for production managers and engineers: Numerous materials handling methods compete with one another, appropriate dimensioning is not easy, and even the material of which the components are made must be carefully selected depending upon the fluid to be handled. Exact dosing in all of the process steps also plays a very important role. In addition to challenging media, which have to be conveyed safely and reliably, there are other factors that pose challenges for operating companies. All parameters must be perfect to ensure safe, reliable, and efficient operation.
