In-Lubricator Oil Level Controller with Safety Switch

OPERATING PRINCIPLE

---

Series 507 Oil Level Contrillers 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 saftey switch will be activated.

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 Non-mercury switch will not react to vibration
