Epe Italiana AS20P210CL9V8C0C0 Accumulator 20 LT

Description A hydro-pneumatic accumulator is a device used specifically for storage of liquid under pressure. As liquids, for all practical purposes, are incompressible, this objective is achieved by utilizing the compressibility of gases. A flexible rubber separator i.e., bladder is fitted into the accumulator shell. An inert gas - nitrogen - is filled into the bladder through a pressure valve to a pressure P . The bladder expands, filling 0 the entire volume V of the accumulator shell. 0 When the system pressure P is higher than the gas 1 precharge pressure P , the liquid enters the accumulator 0 and the bladder is compressed reducing the gas volume to V .1 Should the liquid pressure rise to P , the volume of gas 2 reduces to V with an attendant rise in pressure, thus 2 balancing the Liquid pressure. A potential energy is now stored in the accumulator to be utilised whenever needed.Certification The EPE bladder accumulators are generally designed & manufactured according to European directive. They can also be supplied as per ASME or others on request. Materials In standard version, the shell is made of carbon steel and painted on the outside with a coat of rust inhibitor; the valves are made from carbon steel - phosphated. This configuration is suitable for oils and non-corrosive liquids. Options for shell in stainless steel / aluminium / titanium alloy are available on request. Shells Nickle plated / Rilsan coated or others are also available on request.
