Since hydraulic accumulators are pressure vessels, the installation, commissioning, disassembly and maintenance should be performed by professionally trained and qualified personnel. Warranty. Parker Hannifin warrants the A Series and ACP Series. Piston Accumulator shall be free from defects in material.
A hydraulic accumulator is a pressure vessel containing a membrane or piston that confines and compresses an inert gas (typically nitrogen). Hydraulic fluid is held on other side of the membrane. An accumulator in a hydraulic device stores hydraulic energy much like a car battery stores electrical energy.
The selection of the volume is stepless. Bosch Rexroth piston accumulators are always engineered to order, and are customer-specific. Standard diameters are 360 and 500 mm and are variable in length up to 5 500 mm. They operate in temperatures from -20° c to 60° C, have a maximum piston speed of 3 500 mm/sec and maximum pressure of 220 bar.
Piston accumulators are the optimal choice when fluid energy storage, hydraulic shock absorption, auxiliary power, or supplemental pump flow is required. Customizable by size and pressure, piston accumulators can be uniquely designed to fit your needs.
Parker''s piston accumulators are compatible with a wide variety of fluids. Standard accumulators (with nitrile seals) may be used with petroleum-based industrial oils or water-based flame resistant fluids. Optional seals compatible with most industrial fluids are available with temperature ranges from -45°F to 325°F (-43°C to 162°C).

The piston accumulator series SK350 is HYDAC''s most versatile series with a repairable design and large selection of options. The largest range of possible sizes, material construction, and other options are offered. Standard and Low Friction piston designs are available for superior performance and flow rates.
The accumulator is a pressure vessel for storing hydraulic pressure in it utilizing compressible and decompressible nature of nitrogen gas. The accumulator has a similar function to the rechargeable electrical battery, in the field of electricity. Electrical energy is stored to the battery. In the hydraulic field, fluid energy (pressure of the
The Basics. A hydraulic accumulator is a pressure vessel containing a membrane or piston that confines and compresses an inert gas (typically nitrogen). Hydraulic fluid is held on other side of the membrane. An accumulator in a hydraulic device stores hydraulic energy much like a car battery stores electrical energy.
Tobul piston type accumulators from 2″ to 24″ in diameter with fluid capacities from 4 cubic inches to 300 gallons and oeprating pressures up to 20,000 PSIG. In the realm of fluid power systems, the piston accumulator and piston hydraulic accumulator represent pinnacle components for energy storage, pulsation dampening, and shock absorption.
Piston accumulators are highly-customizable and can handle much hotter and colder temperatures than bladder accumulators. We specialize in quick quoting and delivery.

Features: Two sealing rings double the sealing capacity over OE. Our new additional center ring seals in a previously unused area of the bore allowing reuse of the valve body or case even when damaged by side-loading of the OE design accumulator piston. The third ring, combined with a shallower groove in the piston, acts as a guide preventing

For example, a piston accumulator may have a 1000-psi precharge, but to move a set piston may require 1010 psi. For high-pressure applications, such a small difference is not important. But, if you have a low-pressure application in the 130- to 150-psi range, a 10-psi breakaway is significant as a percentage of full pressure.
In the realm of fluid power systems, the piston accumulator and piston hydraulic accumulator represent pinnacle components for energy storage, pulsation dampening, and shock absorption. These devices leverage the mechanical principle of a piston to separate the compressed gas from the hydraulic fluid, ensuring a seamless transfer of energy.
HYDAC piston accumulators can be customised with a chosen diameter and nominal volume. More details can be found here.
