Accumulator IntroductionThe 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
Stage 1
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.
The rubber bladder inside the pressure vessel is pre-charged with nitrogen gas as per the system requirements.
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.
BladderThe bladders are o�ered in several di�erent 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.

ApplicationsGeneral
Diaphragm Accumulators can be mounted in any position but recommended method is vertical with fluid port at the bottom for optimum performance. Accumulators up to 120 CI (2 Liters) can be mounted directly on the hydraulic line. For larger sizes or when strong system vibrations are expected, we recommend mounting brackets for secured installation. Do not weld anything on the accumulator.
Instalation
USE DRY NITROGEN ONLY for precharging the accumulator to the desired pressure based on the application requirements. Use SFP recommended charging kits for any pre-charge and maintenance. Ensure the hydraulic pressure in the line is vented completely before conducting any pre-charge maintenance.
Precharging
Benefits
Shell – Electron beam welded high strength steel.
Diaphragm – Two options available that are compatible with most mineral oils.
Nitrile (NBR) as a standard (50F to 1760F)
ECO (Hydrin) for low permeation and extreme temperature range (-310F to +2390F)
Fluid Port – SAE Female thread option as standard. Other options available.
Gas Port – Metric M28x1.5 connection with M8x10 screw & bonded seal as standard. Schrader type gas valve option available.
Protection – Durable black paint
Certification – Complies with European PED 97/23/EC without CE marking.

Charging & Gauging Unit
Although any inert gas can be used to pre-charge the accu-mulator, 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 di�erently.
For optimum and reliable operation of accumulators, it is important to fill and maintain the correct nitrogen pre-charge pressure. We recommend checking pre-charge pressure regularly. Charging & gauging kits are designed to fit on a commercially available nitrogen bottles. Charging instructions are provided with charging kit for safe operation.
Our general recommendations for nitrogen pre-charge varies by application and are as follows.
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.
Accumulator must be pre-charged to the required pressure prior to operation to avoid the risk of bladder failure when commissioning.

Design Features
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 e�ect 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.
Material used for clamps and brackets are typically hot or cold rolled galvanized steel that o�er exceptional strength and durability. A rubber cushioning sleeve on the clamp and a rubber grommet on the bracket provide isolation from system vibrations.
Mounting AccesoriesWe 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.

MOUNTING & INSTALLATION
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 e�ciency 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 also globally with all the applicable approvals and certifications. We also o�er custom engineered products to suit various applications and industries.

SFP manufactures special piston and bladder accumulators with custom options in low and high pressure applications.
SFP has developed a unique reservoir for hydraulic systems based on cyclone principle. The technology uses the di�erence 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,
Piston Accumulators with electrical limit switchesPiston Accumulators with position indicatorsHigh pressure bladder accumulatorsBladder and Piston Accumulator racks upon customer request
