General Information

Description

The Murphy LM500 model maintains the crankcase oil level of an engine, pump or
compressor. Adjusted to the correct running oil level, the LM500 will replenish oil as it is used.
The low level switch will alarm and/or shut down the equipment if the supply oil is lost and the
equipment continues to use oil. The LM500-TF model includes a test fea tur e that confirms both
the float and switch are operating correctly with a single press of the test button.
