The automotive industry deals with a hugely diverse (and often expensive) range of product components that need to be pumped safely and controlled. Product components in this industry can be exceptionally challenging; many are of particularly high viscosity and often contain abrasive additives.

Features and Benefits

  • Transferring specialist Automotive Paints
  • Pumping through Paint Mills in the automotive paint industry


The printing industry handles a diverse range of products, some of which boast highly challenging characteristics. Components in this industry can be of especially high viscosity, and they often contain abrasive additives.


The manufacturing industry deals with an incredibly diverse range of products and materials. Many of these components possess highly challenging characteristics, including high viscosity and abrasive additives.

Features and Benefits

  • Transferring any product up to 300,000 Cps
  • Ability to pump particles up to 25mm cube
  • Pumping product from road tankers into bulk containers
  • Pumping coolants in large manufacturing plants

Chemical Process Industries

The chemical industry deals with some of the most hazardous materials in manufacturing including acids, caustics, and solvents, all of which need to be pumped in a safe and controlled manner. Any spillage or leakage can be extremely harmful to both onsite personnel and the local and general environment.

Features and Benefits

  • Transferring acids and other aggressive chemicals at up to 135°C (275°F)
  • Pumping CIP Chemicals into dosing systems
  • Pumping Solvents
  • Pumping adhesives
  • Emergency response applications

Water Treatment

By 2030, global water demand is projected to rise to 6,350 cubic kilometers, up from 4,500 cubic kilometers in 2010. The largest end-user segment of the diaphragm pump market is still the water treatment industry. However, water is not only precious also it is incredibly scarce in some regions of the world.

That increase in demand for water will spill over into an increased need for water treatment operations. Diaphragm pumps are essential for treatment processes like coagulation, iron sequestration, disinfection, and helping ​with odor control, phosphorous control, and solid conditioning.

Overall, water treatment accounts for 18% of all diaphragm pump use worldwide. Many developed countries may already have diaphragm-based water treatment systems in place. Still, other parts of the world are only beginning to implement country-wide measures to provide safe and accessible water.
