Kussmaul Auto Pump AC – 120V 60Hz

Kussmaul Auto Pump 120V

The Kussmaul Auto Pump AC is a 120 volt 60 Hz shaded pole A.C. motor operating a single cylinder air compressor designed specifically for installation on vehicles with air brakes.  During long idle periods of the vehicle, when even the slightest seepage can cause an air brake system pressure to drop below the brake lockup pressure, the Auto Pump AC automatically starts to maintain the pressure. 
The Kussmaul Auto Pump AC motor is directly coupled to the compressor section eliminating all belts and pulleys and assuring long life and reliable operation. A heavy-duty pressure switch is adjusted to start the compressor when the system pressure drops below 75 PSI and stops the compressor when 95 PSI is attained. The start-up pressure is field adjustable – the pressure differential between start-up and stopping is fixed. The moisture trap provided permits routine draining of accumulated moisture in the Auto Pump output line.
