507 SERIES OIL LEVEL CONTROLLERS FOR MECHANICAL LUBRICATORS

OPERATING PRINCIPLE:

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.

APPLICATIONS:

• Lincoln, Premier, and Mega Lubricator Boxes

FEATURES:

• Valve design eliminates lubricator box overfill due to contaminates in the oil
• Controls oil level in lubricator
• Low level safety switch protects against engine and pump repairs due to lubrication failure
• Inlet pressures up to 60 psi
• Non-mercury switch will not react to vibration

MODEL K507-L

The standard valve seat material is Buna-N, but may be ordered as Fluorocarbon for other types of lubrication. A 1/2" FNPT conduit connection is standard. The switch is case to ground, the circuit will remain open until the switch is activated.

MODEL 507-M

The standard valve seat material is Buna-N, but may be ordered as Fluorocarbon for other types of lubrication. A 1/2" FNPT conduit connection is standard. A basic two wire SPDT switch with form C contacts is standard.
