Endura-Flo 4D350  High Pressure Diaphragm Pumps

350 cc per cycle and 400 psi (28 bar) maximum fluid pressure in a compact pump

Jaa |

The Endura-Flo 4D350 ensures long-lasting durability and can withstand runaway conditions better than other diaphragm pumps. This easy-to-install pump offers low pulsation output and smooth changeover for quick color changes, saving you time and money. 

  • 350 cc per cycle 
  • Highest pressure ratio in the industry at 4:1
  • Redesigned diaphragm lasts longer and can hold up to extreme operating conditions better
  • Easy access to critical components provides fast online maintenance
  • Superior durability for abrasive materials
  • Innovative design ensures easy access to critical components for fast, online repair
  • Minimal solvent to flush and consistent startup pressure make it perfect for multiple color change and piggable systems
  • DataTrak option prevents runaway and tracks material usage
  • Pumps are easily configurable for custom installations
