Principle: Oil Circulation System
With the start of the machinery to be lubricated, a delivery pump supplies oil via an oil filter and progressive distributors towars the lubrication points.
Proper function of the system can be monitored either by a pressure gauge or by a proximity switch built-on the progressive distributor. Returning oil is collected in the tank.Lubricant level in the tank is monitored by level switch.It is possible to install a cooler or heater onto the tank

Principle: Grease Lubrication
By using a pneumatic barrel pump, main supply line is under constant pressure. Upstream of the progressive distributor there is a high-pressure solenoid valve that is interlocked with the machinery to be lubricated (possibly by an exixting PLC control). After expiration of the pause time, the solenoid valve opens and the distributor stars operation. The proximity switch built-on the progressiv distributor, generates a signal after the distributor has made complete cycle.
This signal is evaluated in the electrical control.Solenoid valves of a differente sections can be opened independently from each other according to lubricant requirements.
