HYDRAULIC ACCUMULATORS
Accumulator Introduction
Design Features
The hydro-pneumatic accumulator stores energy in the form
of pressurized hydraulic fluid and releases to the hydraulic
system when demanded either immediately or intermittently.
A separator between the compressible dry inert gas such as
nitrogen and incompressible hydraulic fluid allows the stored
fluid to be discharged per the system requirements. The most
common types of accumulators are Bladder type which uses
bladder as a separator to store gas, Piston type which uses piston as a separator between the gas and fluid chamber and Diaphragm type which uses a diaphragm as a gas separator from
hydraulic fluid. All three types of accumulators have their own
advantages and limitations which should be considered when
selecting for an application.
Accumulator Shell
A bladder accumulator shell is forged from a chrome molybdenum high strength carbon steel material that is seamless
with hemi head ends. They are designed and manufactured to
ASME code material and design specifications. The pressure
rating is based on a 4:1 safety factor exceeding the requirements of ASME code.
Bladder
The bladders are offered in several different material choices
and operating temperatures to be compatible with various fluids and severe applications. Refer to the table on page 5 for the
common choices for the bladders.
Bladder Accumulator Benefits
Industries and Applications
Improve system performance and efficiency - Reduce operation and maintenance costs - Ensure fail-safe conditions
- Increase uptime and prolong system life expectancy - Quick
response time - Contamination tolerant - Safety – Cannot be
disassembled under pressure - Lighter weight - Recommended
for water based or low lubricity fluids - Field repairable - Parts
interchangeable with major brands.

Accumulator Operating Principle - Typical Operation
The rubber bladder inside the pressure vessel is pre-charged with nitrogen gas as per the system requirements.
Stage 1
Accumulator is pre-charged with nitrogen gas based on the system requirements. During this stage, the hydraulic system pressure is lower than the pre-charge pressure.
Stage 2
The Hydraulic system is pressurized causing the fluid to enter the accumulator when the fluid pressure exceeds pre-charge
pressure (Charging cycle).
Stage 3
The system pressure reaches to the maximum limit filling the accumulator to its maximum capacity. This is a fully charged state.
When system pressure falls, the compressed nitrogen gas forces the fluid from the accumulator into the system until it reaches
system minimum pressure (Discharge cycle). A typical accumulator function cycle is between stage 2 and stage 3 during operation.

regularly. Charging & gauging kits are designed to fit on a
commercially available nitrogen bottles. Charging instructions
are provided with charging kit for safe operation.

Parts List
Although any inert gas can be used to pre-charge the accumulator, we recommend to use high purity dry nitrogen gas only for
pre-charge. Never use shop air or oxygen to avoid any risk of
explosion. Accumulators are normally shipped with pre-charge
pressure of 25 psi for shipping purpose only unless otherwise
specified by the customer differently.
Accumulator must be pre-charged to the required pressure prior to operation to avoid the risk of bladder failure when commissioning.
Our general recommendations for nitrogen pre-charge varies
by application and are as follows.
Energy Storage – 90% of the minimum system operating pressure.
Shock Absorption – 60%-75% of the normal working pressure.
Pulsation Dampening – 60%-80% of the normal working pressure.
The above recommended pressures must be adjusted
taking operating temperatures into consideration. Pre-charge
pressure must be checked during first week in operation.
Subsequent maintenance should be done 3 to 6 months
depending on the severity of the application. High cycling and
high temperature applications require maintenance every 3
months.

MOUNTING & INSTALLATION
Recommended Installation
Recommended bladder accumulator installation is in vertical
position with fluid port at the bottom for optimum performance.
Bladder accumulator mounted horizontally will reduce the
performance due to trapped fluid and service life of the bladder
reduced due to excessive wear when rubbing against the shell.
Accumulators subjected to external forces may also have
detrimental effect on performance and life expectancy. We
also recommend the use of our mounting clamps and brackets
to ensure rigid and safe installation of the accumulator in the
hydraulic system.
Mounting Accessories
We strongly recommend using our mounting accessories to
install accumulators to ensure safe and secure installation.
They are designed to carry the weight of the accumulator as
well as counteract any forces or vibrations transmitted from
the hydraulic lines. Recommended installation is vertical with
Hydraulic port down.
Design Features
Material used for clamps and brackets are typically hot or cold
rolled galvanized steel that offer exceptional strength and durability. A rubber cushioning sleeve on the clamp and a rubber
grommet on the bracket provide isolation from system vibrations

ASSEMBLY
Optimized Assembly Process on Conveyor System
We supply to the line and maintain continuous flow where operator works with designated work zone. This is a break away from the
current industry practice of bench building or line building with multiple operators either side of the line. By having synchronized
line feed we can outperform the competition in term of efficiency and delivery, whilst maintaining a quality standard that meets
the customer’s need and expectations.
From our factory in Katy, Texas, we assemble and ship wide range of bladder accumulators not only for the American market but

Cyclone Tank
Servi has developed a unique reservoir for hydraulic systems
based on cyclone principle. The technology uses the difference
in density between oil and air. Rotation accelerates the deaeration of oil thereby reducing the reservoir volume by up to 90%
compared to a traditional reservoir. Some of the benefits from
this include:
•
