Ultra-Micro Output PurgeX has the ability to deliver extremely fine, precise amounts of lubricant with each cycle.  It has the same characteristics as standard PurgeX, but uses a smaller diameter piston.  This results in a very fine degree of control over a greatly reduced output volume.  It is particularly adept for use with near-dry machining.  Precise volumetric delivery is achieved with the positive displacement design. 

This PurgeX is operated with compressed air between 40 to 120 PSI.  An integral 12” coaxial spray nozzle is flexible yet rigid enough to allow for precise positioning.  Longer nozzles are available.  Lubricant and air mix at the nozzle tip to disperse grease in a round pattern.  There is a separate needle control for air flow to the nozzle.  No additional air supply or separate air regulator is required, making this a highly efficient spray method.

A 1 ½ oz fiberglass and aluminum grease reservoir is connected directly to the unit.  A spring inside the reservoir ensures that the grease reaches the inlet.  The reservoir is filled through a zerk fitting.  It is suitable for use with grease grades 00, 0, 1 and 2. 

The body is made of anodized aluminum alloy and the unit tolerates temperatures from -15° F to 180° F.  Viton seals are used.  The piston diameter is .125”.  The grease delivery per cycle is adjustable between 0 to .0012 cubic inches.  The air inlet and grease fill fitting are both 1/8” female NPT.  This is a single feed unit that is 3 7/32” in length and 8” in height (plus the nozzle length).  There is a 9/32” dia mounting hole.

For applications with multiple feed points, internal Threadapter connections provide common air and lubricant lines for all PurgeX pumps in the same manifold.  It is easy to connect additional PurgeX pumps.  Each PurgeX in the manifold operates as an individual pump with a separate adjustment for lubricant delivery per cycle as well as a separate air spray adjustment stem.  Lubricant delivery can be completely shut off at any time by adjusting the piston to the fully closed position.

 
Two 3/4" spacers are shipped loose with the unit.  They slip over the mounting bolts (supplied by customer) between the pumps and the mounting surface.  They account for the width of the reservoir so that the pumps install parallel to the mounting surface.

PurgeX functions accurately and reliably.  Any entrapped air and other impurities are automatically purged from the pump when the piston slightly over-travels the pump chamber with each cycle

Additional requirements include a 3-way solenoid valve, timer or sequence signal, and tubing and fittings.
