PurgeX has the ability to deliver very small amounts of lubricant with each cycle and can be rapidly cycled for greater volumes; it is excellent for high speed applications. 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.
This PurgeX features air and liquid inlets on two sides, allowing multiple PurgeX units to be connected with tubing. This results in the ability to link lubrication points over a long distance using a single air supply and liquid source.
This PurgeX is operated with compressed air between 40 to 120 PSI. 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. Buna-N seals are used. The liquid delivery per cycle is adjustable between 0 to .012 cubic inches. The piston diameter is .250” and can travel as much as .250” per stroke. The air and liquid connections are 1/8” female NPT. Each feed has a 1/8” female NPT outlet. This is a 7 feed unit that is 9.87” in length and 4.06” 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 all 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.
Some amount of pressure from the grease supply is necessary. That pressure can be achieved with a small reservoir that uses spring force or larger air pressurized reservoirs. PurgeX functions accurately and reliably when drawing lubricant from these sources. 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 pressurized reservoir, 3-way solenoid valve, timer or sequence signal, and tubing and fittings. Because grease tends to be slow-moving even when under pressure, the distance between the reservoir and pump should be as short as possible.
