PNB is actuated pneumatically by a solenoid valve to discharge oil intermittently. The pneumatic pressure supply controls the output pressure of PNB.
PNB requires 4-8 kgf/cm2 pneumatic pressure supply and 5 seconds above ON/OFF time of the solenoid valve to work functionally.
PNB has to work with volume distributors to deliver the metered quantity of oil to the lubrication points.
PNB has a pressure gauge that enables the user to check the operating pressure easily.
PNB has a NC contact float switch that detects the oil level automatically and sends signals when the oil level is low.
An 8kgf/cm2 socket pressure switch can be added to PNB on request to detect the operating pressure automatically.
A magnetic filter and a partition can be added to PNB on request to filter the oil that returns to the oil tank through the cyclic inlet.
● 3L oil tank and above can add a magnetic filter.
● 3L, 4L resin oil tanks, and 8L iron oil tanks can add a partition.
