4 Over 30 years of piston accumulators 0496 PMC CYLINDERS AB have 30 years experience of manufacturing piston accumulators and are now introducing two new series that are CE-approved as per PED 97/23/EC: PMC PAC (Piston Accumulators Carbon steel) PMC PAS (Piston Accumulators Stainless steel) PMC s focus on their own piston accumulator series means that, to an even greater degree, they can satisfy the demands to be a total hydraulics supplier. PMC will manufacture a standard prograe covering several different products, as well as for specific special applications. Series PMC PAC Carbon steel piston accumulators for 250 and 350 bar operating pressure are particularly suitable for applications in the fields of Mobile systems, Industry, Energy and Offshore & Marine. Series PMC PAS Stainless steel piston accumulators that are suitable for Offshore & Marine with a operating pressure of up to 350 bars. Examples of areas of use The piston accumulators are used in applications for shock absorption, braking systems, energy storage, backup power and volume compensation. Many advantages Can be easily connected to gas (backup) bottles to generate larger accumulator systems. As additions, visual as well as electric piston position indicators can be installed. We provide complete accumulator stands and other hydraulic solutions. PMC also market accessories and other products such as pulsation dampers, gas bottles, safety blocks, burst discs and charging kits. In addition to our standard range, we can offer connections and specific applications in different sizes as required. Effectiveness pays With PMC handling the entire process from design and manufacture through to sales, decision paths are short and leadtimes reduced, which all results in a positive effect on prices for you, the customer. In cooperation with PMC s different companies, together we can always find the optimal hydraulic solution. 4
