Hydraulic Power Packs

Hydraulic power packs (HPU)
A hydraulic power pack is a device that will generate and store hydraulic energy at one or
more different pressure levels ready for later use. A hydraulic power pack can be installed
inside an enclosure or on a skid.

Main component in this device are:

• The hydraulic reservoir (sized in accordance with the required fill-up of tubing/hoses
  and swept volume of various actuators in the field).
• Motor/pumps, usually motor/pumps are redundant (two or more pumps for each
  pressure level). Motors can be either Electrical or Pneumatic driven.
• Pressure transmitter / switches for start/stop control of the pumps.
• Accumulators, for hydraulic energy storage.
• Relief valves for protection of equipment and field runs. Relief valves are set 10%
  above working pressure, but should never be higher than maximum allowed working
  pressure of tubing/field equipment
