Murphy Level Regulator LM500

These level switches are in stock.

The Murphy LM500 is a reliable level switch that keeps the crankcase oil level of engines, pumps and compressors topped up automatically. As soon as the oil level drops, a float-operated valve opens and the LM500 refills from an external oil tank without any manual intervention. The switch can be set so that a critically low level sounds an alarm and shuts the installation down automatically, by means of the built-in switch.

The filling system is only complete with a supply vessel or a small tank.

We also stock the standard Murphy level switches (EL 150 K1).
