The air backing added to the diaphragm gives this model the power to deliver up to 28 Bar fluid pressure.

Maximize your performance with the industries highest output pressure.

Easily convert your 4:1-model to a 3:1 with our Conversion Kit.

  • Low Pulsation and Low Shear
  • Ideal for fluid transfer and supply, small paint circulation and piggable paint ystems
  • Easy access to critical components for easy maintenance and fast repair
  • Diaphragm requires very little solvent to flush
  • 360 ° mounting possibility
  • Consistent start-up pressure (ideal for piggable systems)
  • Pumps are easily configurable for custom installations
  • DataTrek option prevents runaway and tracks material usage
