FloJet 2100-777 Duplex 12v DC Diaphragm Pump


The Flojet Duplex is available in various performance ranges, voltages and with a choice of diaphragm and check valve materials, making it easily adaptable to a diverse range of applications.

The Flojet 2100 series is self-priming.

It may be located several feet from the tank, above or below the liquid level (it is not a submersible pump.)

For vertical pump mounting be sure that the motor is located on top.

Pump head may be rotated in 90° increments to simplify plumbing.

  • Built-in pressure switch automatically starts and stops pump instantaneously when discharge valve is opened and closed.
  • Can run dry without damage and handle liquids up to 54°C (130°F).
  • Duplex Diaphragm Design eliminates troublesome shaft seal.
  • No metal contact with liquid being pumped.
  • Ball bearing drive throughout pump and motor assures longer pump life.
  • Excellent self-priming capability. Pump may be located above the liquid level.
  • Powerful, permanent magnet motor with low current draw and long life brushes.
