PurgeX has the ability to deliver very small amounts of lubricant with each cycle and can be rapidly cycled for greater volumes. Precise volumetric delivery is achieved with the positive displacement design. There is no “after drip,” which makes PurgeX a very effective lubrication solution where product contamination is a concern.
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.
This PurgeX is operated with compressed air between 40 to 120 PSI. The body is made of anodized aluminum alloy and the unit tolerates temperatures from -15° F to 180° F. Buna-N seals are used. The grease delivery per cycle is adjustable between 0 to .012 cubic inches. The piston diameter is .250”. The air inlet and grease fill fitting are both 1/8” female NPT. Each feed has a 1/8” female NPT outlet. This is a 4 feed unit that is 7” in length and 8.06” in height. There is a 9/32” dia mounting hole on each feed.
For applications with multiple feed points, internal Threadapter connections provide common air and lubricant lines for PurgeX pumps in the same manifold. Each PurgeX in the manifold operates as an individual pump with a separate adjustment for lubricant delivery per cycle. It is easy to connect additional PurgeX pumps. 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.
