Parker Conflow’s Code 4818 is a unique emulsion mixer which supplies a constant, accurate mix ratio of soluble oil and water to provide fire-resistant hydraulic fluid to power roof supports on the coal face.

The only emulsion mixer of its type for underground mining available anywhere in the world, Code 4818 requires no electrical power, as it is driven by the 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 it mixes with the incoming water to create an emulsion. By adjusting a regulator valve on the oil inlet, different mix concentrations can be achieved.

When specifying the product, the customer needs to state oil type, whether synthetic or mineral. To enable efficient use of the oil, Parker Conflow offers the option of a check valve to prevent the oil draining away.

Code 4818 is available as 1/2" water inlet port, 1" emulsion outlet port, 1/2" oil inlet port.
It operates to a maximum working pressure of 138 bar.
