A single-line progressive system uses the flow of the lubricant itself to cause individual metering valves and valve assemblies to cycle. The cycling of the valve causes the pistons to move back and forth in a cylinder of a specific diameter (bore). When a piston moves forward, it displaces lubricant

ensures a measured and consistent amount of lubricant is applied. (Over-lubrication can result in over-heating, spoiled product, damage to bearing seals and a need for extra cleaning. Under-lubrication can result in higher running costs and decreased machine longevity.) Effective lubrication reduces

The dangers of accessing difficult to reach lubrication points while a machine is running are avoided. Machines can be running when lubrication takes place, thus decreasing disruption to production. Manual lubrication may result in over- or under-lubrication whereas an automatic lubrication system

A dual-line parallel system also uses hydraulic pressure to apply lubricant in measured amounts. In an alternating pattern, one line is building hydraulic pressure while the other is venting pressure. The dual-line parallel system can apply lubricant to hundreds of lubricant distribution points
124:
Pressure-relief systems (also called piston lubrication systems or positive displacement injector (PDI) systems) use a piston to apply an accurate lubricant volume to the lubrication point. A pressure relief system is used when the volume of lubricant applied must be precise.
128:
Resistant oil lubricators use the resistance of an outlet to control a continuous flow of lubricant. Further control is given by proportion adapters or oil meter adapters. Resistant oil lubricators are used when a precise volume of lubricant is less essential.

Oil systems are used in stationary machinery such as a CNC mill, for example. Grease systems are used in mobile machines such as trucks, mining and construction equipment. The appropriate lubricant for an automatic lubrication system can be determined using a

which, in turn, causes the next piston to move forwards. The valve output is a fixed volume however, the amount of time taken for each piston to move back and forth can be varied and pre-programmed. Lubrications points are arranged in

There are a variety of feed line systems used in automatic lubricating systems. These include single-line progressive systems, single line parallel systems, dual-line parallel systems, mist lubrication and multiport direct lubricators.

signals the control system that lubricant has been applied at all the lubricant distribution points have been reached. The pump stops, pressure is vented from the system and the lubricant is directed back to the pump reservoir.

Automatic lubrication systems can be categorised according to the type of lubricant, the method of controlling the volume of lubricant and or the method of distributing the lubricant.
