Description
The AT-67207 is a completely reliable heavy duty device
developed specifically to automatically control engine
speed to meet system demand. Low current, high torque,
solid state switching and electronic clutch make it ideal for
all automatic and semiautomatic engine systems. Used
with the appropriate Murphy SWICHGAGE
®
, near constant
pressure, level and load can be maintained. Check with our
engineers for help with other applications where speed
control can improve your system.
Applications
Pressure
• City Water Systems.
• Water Flood Injection.
• Sprinkler Lateral Changes.
• Make-up if a “Gang Pump” stops.
• Multiple Hose-reel Irrigation Systems.
Level
• Water or oil storage tanks.
• Waterflood tanks.
• Sewer disposal systems.
• Flood control catch basins.
Temperature
• Multi-engine cooling systems.
• Air conditioned chilled water systems.
Engine load
Empty or fill reservoirs with a lower horsepower engine—
fast when head is high—slow when head is low.
Fully adjustable stepper kit
Meters signal in adjustable pulses. Prevents surging on
critical applications.
