BLADDER ACCUMULATORS

A hydraulic bladder accumulator is the hydraulic equivalent of a spring in that it stores energy and dampens an impulse or force.

Storage of an incompressible, high pressure hydraulic fluid is accomplished through the use of compressible nitrogen gas in an elastomeric bladder enclosed in a high strength steel pressure vessel. This essentially comprises the assembly of the hydraulic bladder accumulator.

The nitrogen gas is precharged to a percentage of the maximum desired hydraulic pressure, and as the hydraulic fluid is pumped into the accumulator, the gas compresses as pressure is increased. Upon demand from the hydraulic system, the stored hydraulic power allows for rapid discharge or absorption of pressure impulses.

APPLICATIONS Energy & Pump Maintenance Savings: Reduction of pump capacity requirements which provide long term energy savings and lower pump maintenance costs.

Surge Control & Shock Absorbers: Pulsation dampening and noise reduction caused by pumps and “water hammer”.

Eliminate Sudden Pressure Drops: Maintain constant pressure on a hydraulic system such as a press line where multiple presses are opened and closed at different times.

Thermal Expansion: Compensates for pressure variations caused by temperature changes within a hydraulic circuit.

Emergency Back-Up & Safety Failsafe: Provides stored fluid power for operation of hydraulic equipment power failure.

FEATURES

Over 40 years of proven reliability.

Cannot be disassembled under pressure.

Interchangeable with accumulators from other

manufacturers.

Genuine PacSeal Hydraulics Bladders are

manufactured in the USA using our tooling andproprietary manufacturing processes. Standard rubbercompounds are Nitrile and Cold Weather Nitrile.

Shells are manufactured from chrome-moly steel,

seamless non-welded, pressure tested to 1.5 timesworking pressure and ASME “U” stamped after thirdparty witness. Offered in bottom load and top repairableconfigurations.

Standard fluid ports available are 1-1/4” NPT, 2” NPT

and #24 SAE, machined from alloy steel and coated forcorrosion prevention. Other port types and materials areoffered by special order.
