Pressure-Relief Oil Lubricators

Pressure-relief type oil lubrication system is also known as “piston lubrication system” or “positive displacement injector (PDI) system”. The piston distributor determines the output of lubrication points to ensure each lubrication point receives accurate lubricant volume fed by the piston lubricator. This system is suitable for machines that require a precisely controlled amount of oil to each lubrication point.
