Flow Measurement & Control

Emulsion Mixer Code 4818

The Conflow Code 4818 - Emulsion Mixer supplies a constant accurate percentage mix ratio of soluble oil and water. The unit, which will supply this accurate mix over a wide flow range, requires no electrical power, as it is driven by its inlet water supply.

The incoming water drives a rotary paddle wheel, which is connected through a set of transfer gears to a conventional gear pump mechanism.

As the gear pump rotates, soluble oil is pulled into a mixing chamber where the soluble oil mixes with the incoming water to create an emulsion. By adjusting a regulator valve on the oil inlet, different mix concentrations can be achieved.

Typical Applications

  • To provide fire resistant hydraulic fluid to power roof supports on a coal face
  • To provide lubricant coolant for machining tools in any industrial application


  • 1/2" water inlet port, 1" emulsion outlet port 1/2" oil inlet port
  • Maximum working pressure 138 bar
  • Driven by incoming water (NO power supply needed)
  • Mix ratio's from 93:7 down to 99:1 can be accommodated
  • Mix constant for flowrate from 22 to 135 LPM (5 to 30 gpm)
  • Suitable for mineral or synthetic oils
