LF19 Water Pressure Switch
Brand: Mamco
The LF19 water pump pressure switches provide time tested, reliable control for automatic water systems.
The switch is universally accepted for use as original equipment on water well pumps or pumping systems. The pressure switch is available with an on- off knob to manually cut off the pump when not in use.
The LF19 pressure switch can also be used to regulate the tank pressure between two preset values on one phase electrically driven air compressors. This model is also equipped with an unloader valve, which prevents the compressor from starting under load.
Features- Optional auto on/off button for manual compressor shutoff available
