Oil Level Regulators for Lubricators
Description
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 refills.
Each model has a low-level shutdown switch to protect equip-
ment 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 shutdown the equipment.
Model LR579 is for Lincoln lubricators. It features an
adjustable low-level shutdown contact.
LR589 is for Lincoln lubricators, and the LR589NC is the nor-
mally closed wired version of the LR589.
