Product Brochure
The Endura-Flo 3D offers extended durability. The isolated air section of the 3:1 Endura-Flo pump prevents fluids from entering the air section and muffler. Ideal for fluid transfer and supply, small paint circulation and piggable paint systems requiring a lower pressure range and seeking extended diaphragm life.
  • Endure-Flo diaphragms last longer against extreme operating conditions
  • Easy access to critical components for fast online maintenance
  • Pumps offer low pulsation output and smooth changeover for quick color changes, saving you time and money
  • Minimal solvent to flush and consistent startup pressure make it perfect for multiple color change and piggable systems
  • Custom mounting options include rotatable fluid manifolds, mounting brackets and spring loaded check cartridges
