美國GRACO精加工高壓隔膜泵Endura-Flo 4D350
High Pressure Diaphragm Pumps
350 cc per cycle and 400 psi (28 bar) maximum fluid pressure in a compact pump
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.
功能：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
