APPLICATIONS:
Positive Displacement Injectors (PDI's) are an excellent means of
providing oil lubrication to machinery. Using a piston principle, the
PDI will lubricate individual points with specific amounts of oil. There
are 6 output sizes to choose from: 0.06, 0.10, 0.16, 0.20, 0.30, and
0.50 cc's per cycle. A typical system will include a pump, and any
number of PDI's, and the necessary tubing and fittings.
At the start of the lubrication cycle, the PE-34 or PE-44 Series pump
builds pressure. Upon pressure build-up, the PDI's deliver the pre-set
amount of oil. At the end of the lubrication cycle, a pressure unloading
valve opens to return line pressure to 0 PSI. This allows the PDI's to
reset for the next cycle. |
