Oil Level Regulators for Lubricators
LR500 Series
The LR500 Series Level Regulators automatically add
oil to a lubricator to maintain the factory-recommended
level. This function eliminates the work time necessary
for manual checks and rells.
Each model has a low-level shut-down switch to
protect equipment when oil supply is lost. If the
lubricator oil level drops below the minimum operations
level, the low-level switch will operate an alarm and/or
shut down the equipment.
Model LR579 is for Lincoln lubricators. It features an
adjustable low-level shut-down contact.
LR589 is for Lincoln lubricators, and the LR589NC is
the normally closed-wired version of the LR589.
