Hydraulic Power Unit (HPU)
Frames HPUs generally comprise the following
hydraulic components:
• Enclosure
• Reservoirs
• Motor pump assembly
• Filters
• Accumulators
• Control panel
The selection of components and materials depends
on the required flow and pressure rating, but also on
the type of fluid, as well as environmental conditions.
Enclosure
HPUs assembled by Frames can be housed in a
fully enclosed AISI316 cabinet, or we can choose

Accumulators
Frames HPUs include either piston or bladder type accumulators
that store the pressurized hydraulic fluid in order to ensure users a
constant hydraulic flow during operation. Accumulators can be selected
in compliance with a variety of standards, including PED, ASME,
AS1210, NR13 or the standard of any of the major certification bodies.
Controls
HPUs are generally controlled by the client’s control system, which is
connected with the client’s MCC and DCS. However, Frames can also
provide plug & play solutions in which our unit only requires a 230-
690 VAC three-phase power supply to automatically operate pumps
Wellhead Control Panel and provide feedback signals showing the soundness of the operation.
Feedback signals can be directed to the client’s control room,
significantly reducing interface engineering and cabling.
Materials
The materials used in our units match the specific requirements of our
client’s operational environment, and can therefore include the full
range of exotic materials used in tubing and fittings, but also in valves
and instruments.
Process Description
Frames HPUs are built to continuously meet the varying conditions of
our client’s operational processes. Our HPUs include hydraulic pumps
Topside HPU (single or dual arrangement) that draw hydraulic fluids (mineral oil or
water/glycol) out of a supply reservoir/tank and store hydraulic energy
in a hydraulic accumulator bank. The pumps keep running until the
pressure in the accumulator bank reaches a pre-set pressure level.
Each pump header contains a filter set to ensure the cleanliness of the
hydraulic system.
The pump discharge line is typically equipped with isolation valves,
a check valve and a safety relief valve to protect the system from
overpressurization. When the pressure drops to a pre-set level, the
system reactivates the pumps, and the accumulators are refilled with
fluid by the pumps.
While the accumulators are keeping the system’s pressure at the right
level, a pressure control valve enables the operator to regulate the
HPU Pump Section hydraulic pressure moving to the actuated valves.
