Product Features

Duplex II AC Bypass Series

  • Self-priming up to 8' (2.4m)
  • Can run dry without damage
  • Chemically resistant materials
  • Internal bypass standard
  • Built-in back-flow preventer
  • Heavy duty ball bearing drive system
  • UL, CSA and CE models available

The Duplex II series of pumps incorporates the best technology and features developed by Flojet. Everything from the back-flow preventer, check valves, bearings and diaphragm assembly to the motor, has been designed to make this the most reliable diaphragm pump available. Higher efficiency of the pump is evident in the longer life of the motor pump unit. The diaphragm design combined with the new valves makes the pump capable of pulling higher dry vacuum. Duplex II is available in various performance ranges and voltages, and with a choice of elastomers, making it easily adaptable to a diverse range of applications.
