Hydraulic Power Supplies

Производитель: 
_ANCO Engineers (США)

ANCO provides hydraulic power supplies in four flow rate sizes for use in hydraulic testing systems.  We can deliver these power supplies with constant or variable volume pumps.  All power supplies provide for local and remote start and maintain cooling flow through the heat exchanger during periods of no flow to the test system.  The control systems shut down on over temperature, over current, and low oil level.  All systems have water saver valves.  We also offer electronically sequenced pilot/main loops and electronically monitored oil filters options.
