Replaced by FW Murphy LM500

Murphy LM2000 model maintains the crankcase oil level of an engine, pump or compressor. Adjusted to the correct running-oil-level, the LM2000 will replenish oil as it is used. An integral, low-level switch will alarm and/or shutdown the equipment if supply oil is lost and the equipment continues to use oil.

Description

Experience hassle-free oil level maintenance with the LM2000 system! As the crankcase oil level decreases, the LM2000 float opens the nonclogging Thumb-Valve™, enabling a smooth oil flow from the supply tank to the crankcase. Once the optimal level is reached, the float triggers the Thumb-Valve™ to close, preventing overfill.

Key Features:

  • Prevents under/overfill due to “human error”
  • Allows continuous oil level monitoring without shutdown
  • Easy installation
  • Automatic lube level maintenance
  • Equipped with a low-level, 3-wire, snap-action switch
  • Positive-sealing Thumb-Valve™
    Note: Not intended for use with fuel. Keep your system running smoothly with LM2000.
