The ability to deliver very small amounts of lubricant with each cycle is what distinguishes PurgeX® from all other lubrication products.  In fact the name PurgeX®, comes from its designed ability to purge air from the lubrication system.   This eliminates the need to pre-fill lubrication lines during initial installation.  If the  oil reservoir runs low or air is introduced in some other manner into the system, the self-priming PurgeX® will fill lines with lubricant automatically.  The net result is the ability to reliably deliver the smallest amount of lubricant with each cycle.

Each PurgeX® pump has a adjustable lubricant delivery per cycle (see Chart below).
On air operated models, the oil output is adjustable from 0 to .012 cubic inches 
(.20 cc's). on electric motor operated models the output is adjustable from 0 to .009 
cubic inches (.15cc's).  By setting the cycle rate of the PurgeX® pump,  a wide range 
of lubricant delivery over time is achieved.  If needed, lubricant delivery can be 
completely shut off at any time by adjusting the piston to the fully closed position.
