Continuous Mode vs. Shot Mode Operation

The Uni-Max® ST & Pro are factory-configured to operate in either Continuous Mode or Shot Mode. The operating mode is determined at the time of manufacture and cannot be changed in the field.

Continuous Mode

In Continuous Mode, lubricant is delivered continuously while the system's control valve remains actuated.

Operation

• Lubricant delivery begins when the control valve is actuated.
• The pumps continue cycling for as long as the control signal remains active.
• Lubricant delivery stops immediately when the control signal is removed.

Typical Applications

Continuous Mode is commonly used for applications requiring uninterrupted lubrication, including:

• Band saws
• Circular saws
• Milling
• Routing
• Turning
• Continuous machining operations

Shot Mode

In Shot Mode, lubricant is delivered in a controlled number of pump strokes each time the control valve is actuated.

Operation

Shot Mode without Pulse R

• One pump stroke is delivered per actuation.
• The pump stops after the stroke is completed.
• Delivery does not continue if the valve remains open.

Shot Mode with Pulse R

• The Pulse R controls the number of pump strokes delivered per actuation.
• The pumps stop after the programmed number of strokes is completed.
• Delivery does not continue if the valve remains open.

Typical Applications

Shot Mode is commonly used in applications requiring precise, metered lubrication, including:

• Tapping
• Punching
• Cut-off knives and shears
• Die lubrication
• Assembly operations
• Intermittent machining processes
