(7)The piston accumulator series SK280 is a weight optimized, non-repairable design. The non-repairable design and special production process of these HYDAC accumulators save cost, making this series an economic option. Cost-effective - due to the non-repairable design and an optimized production process, Weight reduced series, Reduced installation space, Standard-gas valve (HYDAC Version 1) with integrated M28 x 1.5 male thread, Quick delivery for models with standard connection, SAE fluid ports are available, PED/CE pressure code certification.Accum_Piston_SK280.jpg
(13)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. Features of this series are: Bore Diameters from 2.4" ID to 19.3" ID, Sizes from 1 quart to 200 gallons, Largest range of possible sizes and material options, Standard and Low Friction piston designs available, Largest variety of gas and fluid port options, A variety of piston position sensor monitoring systems are available, ASME, CRN, PED/CE and other pressure code certifications are available.Accum_Piston_SK350.jpg
(51)A piston accumulator consists of a fluid section and a gas section with the piston acting as a gas-proof screen. The gas section is precharged with dry nitrogen gas. Auxiliary gas bottles are frequently used with piston accumulators to provide the required gas volume. Piston Accumulators are a cost effective option for numerous functions involving energy storage, and sometimes shock absorption in a hydraulic or fluid system. They are well suited for applications needing: High Pressure Ratios, Large Volumes of Oil, High Fluid flow rates, Volume monitoring by way of piston position sensor or switch systems.Accum_Piston_spareparts.jpg
