Murphy Level Switch LR857

Introducing the FW Murphy LR857 Lube Level Regulator — your engine, pump, or compressor’s oil level guardian. Designed for small- to medium-volume applications, this regulator maintains the correct oil level by replenishing as needed. Equipped with an integral low-level switch, it alarms or shuts down equipment in case of oil supply loss.

As the crankcase oil level decreases, the LR857 float opens the unique and non-clogging Thumb-Valve™, facilitating oil flow from the supply tank to the crankcase. Once the optimal level is reached, the LR857 float triggers the Thumb-Valve™ to close, preventing further oil flow and ensuring a leak-free seal.

Key Features:

• Integral low-level switch for equipment protection
• Recommended for small- to medium-volume applications
• Three-wire, snap-action switch for versatile installations
• Simple and effective Thumb-Valve™ design
• Significant flow rate for efficient crankcase refill through the LR857

Trust the LR857 to maintain your equipment’s oil level seamlessly and reliably.
