Continuous Integrated Lubrication


Unparalleled precision

The Infinity™ sets a new standard for performance in dual-channel, through-spindle Minimum Quantity Lubrication (MQL) systems. Specifically designed for high-production through-spindle operations, it consistently, reliably, and accurately delivers MQL fluids through the spindle over a wide range of flow rates.

Infinite control

The Infinity™ features a double-acting positive-displacement pump with a control algorithm that delivers accuracy and repeatability, even at very low flow rates. This patent-pending design delivers truly continuous output from 5-500 mL/hr. The positive-displacement pump is not sensitive to fluid viscosity or temperature. This design eliminates the need for calibrations, fluid heaters, and complex parts often used on competitors’ systems.

The Infinity™ gives you direct, digital control of air and fluid flow rates. This provides a nearly unlimited number of settings and allows the Infinity™ to handle any through-spindle MQL operation. The Infinity’s™ precision and repeatability make lubrication-focused process improvement simple and effective. Its reliability makes it a shop favorite.

Dual-channel MQL solution

Use with optional Unist Spindle Kit for dual-channel, through-spindle MQL

When integrated with the machine controller at the PLC level, the Infinity™ allows complete and seamless control from the operator interface. It also has a control interface compatible with other dual-channel, through-spindle MQL systems. Alternatively, the touch screen interface on the Infinity™ gives operators an easy and intuitive interface if a stand-alone solution is preferred.
