507 Series Oil Level Controllers automatically monitor and control the amount of oil in the lubricator housing. This keeps all of the working parts including the pump plungers submerged in oil to reduce wear and corrosion. When the level falls below the operational requirement, the low level safety switch will be activated.
The standard valve seat material is Nitrile, but may be ordered as Fluorocarbon for other types of lubrication. A 1/2” FNPT oil inlet connection and 1/2” FNPT conduit connection is standard. An optional conduit connection wire sealing cap is available for applications with no conduit. The switch is case-toground and the circuit will remain open until the oil supply from the outside source is empty.
