Positive displacement injector lubrication systems (PDI) are divided into two types: oil positive displacement injector lubrication systems and grease positive displacement injector lubrication systems.

Advantages
-Easy to add or reduce lube points – Precise delivery
-Easily monitored system pressure

Oil Positive Displacement Injector Lubrication System
These systems are precise in lubrication delivery. Because some models are adjustable, a single injector manifold can be used to deliver different amounts of oil to various friction points. The working pressure for oil PDI lubrication systems ranges from 1.75 to 3.5MPa. Filterability ranges from 25 to 40μ. Oil PDI lubrication systems are designed for light, medium and heavy machinery.
Application: The system is widely used on textile machinery, machine tools, package machinery, printing machinery, wooden machinery, plastic machinery and glass machinery.

Grease Positive Displacement Injector Lubrication  System
These systems are precise in their lubrication delivery. Because some models are adjustable, a single injector manifold can be used to deliver different amounts of grease to various friction points. Working pressure for grease PDI lubrication systems ranges from 4 to 24.1MPa. Lubricant viscosity ranges from NLGI000# to 2#, while filterability is 150μ. Grease PDI lubrication systems are designed for light, medium and heavy machinery.
Application: The system is widely used on textile machinery, machine tools, package machinery, printing machinery, wooden machinery, plastic machinery and glass machinery.
