Special Instructions

Certification

All hydraulic accumulators are pressure vessels and are

subject to the national regulations and directives, valid at

the place of installation.

Diaphragm accumulator type AMW are designed and

manufactured as per CE/PED in accordance with Directive

2014/68/EU.

As per the provisions of Directive 2014/68/EU all

accumulators with V ≤ 1 ltr and PS ≤ 1000 bar (PS = max.

working pressure in bar) are not allowed to be CE marked

[Article 4 Clause 3] .

Accumulators of capacity greater than 1 ltr are available

with CE marking. When specified every shipping batch is

provided with a conformity declaration and use and

maintenance instructions.

Safety

All pressure vessels must be protected by means of a

pressure relief valve in accordance with Directive

2014/68/EU. Safety Blocks type-B are used for this

purpose.

The most important elements of the safety-related

equipment are the pressure measuring device (pressure

gauge), device for the preventing excess pressure (safety

valves), non-return valves and shut-off valves and devices

for de-pressurising (bleed valves). These functions can be

performed with individual components or integrated in the

form of a safety block type-B.

Special Instructions

It is strictly forbidden to:

- weld or solder or carry out any mechanical operations on

the accumulator.

- engrave or permanently stamp the surfaces of the

accumulator shell and / or carry out other operations that

could affect or change the mechanical properties of the

accumulator

- use the accumulator as a structural element: it should not

be subjected to stresses or loads.

- change the data of the nameplate and / or accumulator

without the permission of the manufacturer.

- use a different fluid than those designed for .

Installation

Before installation, you must perform a visual check to

verify that the accumulator has not suffered any damage

during shipping / handling. Verify that the requested type

matches with what stamped on the nameplate.

We recommend using the accumulator with a suitable

safety valve or a security safety block type B. This device

provides user and equipment protection against possible

damage caused by pressure surges, and also makes the

maintenance of the accumulator easier, so facilitating the

interception and the discharge.

Provide for a clearance of 200 mm above the gas pre-

charge valve to allow access to and control of the pre-

charge equipment.

These accumulators may be installed in any position from

horizontal to vertical (preferably with the pre-charge

valve at the top), and the identification details must be

visible.

Proceed to the assembly so that no abnormal force

affects the pipes connected directly or indirectly to the

accumulator, so we recommend the use of supporting

components and also fastening to avoid the transmission

of vibrations.

Make sure the fluid is compatible with the elastomer of

the diaphragm.

Check that the max. allowed accumulator pressure is

equal to or greater than that of the hydraulic circuit and

that the temperature during operation is maintained

within the range expected.

Make sure the fluid does not contain contaminants

and/or abrasive.

Disposal

Before the accumulator is sent for disposal or recycling, it

should always be discharged completely of the pre-

charge pressure and the gas valve unscrewed. Pre-

loading and checking kits are suited for this task.

For permanently sealed design Accumulators (Version-P)

the diaphragm is preferably damaged on a test rig or the

accumulator is carefully drilled (Ø ≥ 6 mm) on the gas

chamber using a suitable clamp . As the gas flowing out

can draw metal splinters or particles with it, safety

glasses must be worn.

Environmental Protection

Careless disposal of the accumulator and the residual

fluid contained therein can cause environmental

pollution.

Dispose the Accumulator in accordance with provisions

applicable in the country of use.

Fluid residues are to be disposed according to the

respective safety data sheets valid for the specific

hydraulic fluids.
