For over 10 years, we have been helping clients find the right solutions for their applications, whether than be a new Flux pump or replacement model. But don’t just take our word for it..

Read our case study to find out how we helped our customer, a manufacturer of electronic healthcare diagnostic systems, that needed a pump that can handle sludge-like ink residue and flammable solvents. Our experience allowed us to pick a Flux drum pump with a 500mm stainless steel shaft and ATEX motor, perfect for the abrasive tank emptying application.
