Mixer and Water-Driven Proportioner

Mechanical Concentrate Mixers from Eriez Hydroflow eliminate the traditional manual fluid mixing methods which often result in imprecise concentration control. Plant operators at metalworking facilities can choose from the Eriez Drum Top Mixer and the Proportioner to ensure fluid gets neither too lean nor too rich.

When the concentration is too lean, the result is often rust, bacterial infestation and poor tool life. When the fluid concentration is too rich, the rich mixture will waste expensive coolant concentrate, may cause skin irritation and can adversely affect the metalworking fluid's cooling ability at the point of cut.

The durable, all-metal Drum Top Mixer is available in 3 and 10 GPM (11.3 and 37.8 LPM) versions, with mixing range adjustable from two percent to 10 percent. The compact, easy-to-use Venturi mixer jets water through the unit. This creates a vacuum that siphons concentrate from the drum. A needle valve allows for infinite adjustments across the mixture range.

The Eriez Proportioner comes in handy when more accurate and concentrated mixing is needed. The Proportioner--with an average flow rate of 5 GPM (19 LPM)--is a water-driven, positive displacement unit, which dispenses coolant on demand at the desired concentration. Mixing ranges are available from one percent to 25 percent. Special units are also available for highly alkaline parts washing fluids, 12 and 25 GPM (45 and 95 LPM) units are available.

The adjustable, non-electrical Proportioner provides consistent concentration at all times despite varying water pressures or fluid levels in supply containers. Because it is driven by the plant's water supply pressure, it also can be used to supply properly mixed fluid through overhead piping to the machine tools--without using a booster pump.

Mixture ranges for the Eriez Proportioner include 8 oz. one percent to four percent; 16 oz. one percent to eight percent; 32 oz. two percent to 15 percent.
