Industrial paints and protective coatings need a system that can ensure your materials flow consistently and smoothly. That’s why experts who design systems that handle the transfer of these high-solids materials trust MouldAir diaphragm pumps and piston pumps to maintain a steady stream.
High-performance coatings contain pigments, resins, and other filler material that improve surface adhesion and workability. But they also have increased abrasive properties that can lead to extended downtime. MouldAir piston pumps and diaphragm pumps combine lasting durability with expert engineering to give you a paint transfer pump capable of resisting wear while providing consistent flow and perfect finishes, in any type of industrial paint or coating application.

Superior Performance with Abrasive Materials

Designed to meet the demands of constant use in abrasive-heavy industries without wearing down, MouldAir piston pumps can be configured with materials of construction and packing materials that deliver superior resistance.

  • Our plunger rods and cylinder tubes feature the exclusive MouldAir ceramic ultra-coating, extending service life up to twice as long and comes standard on all 4-ball pumps and available on all 2-ball pumps
  • Available in affordable high-grade stainless-steel construction
  • Electro-polished and passivated for material compatibility and corrosion-free operation
  • Eight packing options are available, including ultra-high molecular weight polyethylene (UHMW-PE), for even better material compatibility and maximum abrasion resistance
  • Chrome-plated stainless steel plungers for superior resistance to rust and corrosion

The MouldAir Difference

MouldAir piston pumps and diaphragm pumps deliver the power, adaptability, and dependability you need in an airless paint pump or industrial coating system. Keep things moving with our reliable pump features:


  • 6” stroke delivers greater displacement with less wear than 4” stroke pumps
  • Fewer moving parts lead to easier service and safer operation
  • Time-tested design that’s been proven for long-term use
  • Stainless steel or carbon steel construction available depending on your application
