Positive displacement pump PE-34 / PE-44 series
Trico
The PE-34 and PE-44 Series use positive displacement injectors (PDI's) to deliver precise amounts of oil to the lubrication points. Positive displacement systems are auto-cyclic gear pumps which contain a depressurizing mechanism to return line pressure to 0 PSI. The PE-34 Series pump has built-in cycle controls, while the PE-44 Series uses external controls for the lubrication cycle.
