DynaMAX 550P/560P/575P Waterjet Pump Operator Manual 811390 45
Optional equipment
Electrical head exchanger
Standard pumps have a water-cooled heat exchanger. In an air-cooled system, the temperature
sensor in the hydraulic fluid tank turns on an external heat exchanger.
Electrical interlock
An electrical interlock on the top cover prevents access to the components on the top deck while
the system is pressurized.
The interlock is connected to the emergency-stop circuit. When the top cover is opened, the pump
switches to emergency-stop mode and bleeds off all pressure.
