No need for unloaders or bypass valves, simply add gauges and hoses to suit your application.

  • Switchable between single and two-stage mode by turning a valve
  • Use single stage mode for most of the transfer - when the inlet pressure starts to drop - switch to two-stage mode to pull vacuum as your process requires
  • In single stage mode - the pump has identical performance to EXT420
  • Two stage mode allows the pump to draw vacuum down to 23-in. Hg
