Product Detail
Series 2000 & 3000
Quick Overview
PISTON ACCUMULATOR
Rated Pressure: 2000 to 3000 PSI (138 to 207 bar)Nominal Bore Size: 3 to 12 in (8 to 30 cm)
Max Recommended Flow: 220 to 3450 gpm (834 to 13061 l/min)
Pressure Ratings
Parker Series 3000 piston accumulators are rated at 3000 PSI and a minimum 4 to 1 design factor. Pressures over 3000 PSI, see Series 4000 and Series 5000 accumulators. For pressures over 5000 PSI consult factory.
Fluids
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 +320°F (-43°C to +160°C).
Precharge
Units are shipped with a nominal nitrogen precharge as standard. For specific precharge pressures, specify at the time of order.
Auxiliary Gas Bottles
When space does not permit the installation of the required piston accumulator, a smaller accumulator may be used by connecting it to an auxiliary gas bottle(s) that can be located in a nearby spot where space is available. In some cases, a piston accumulator and gas bottle combination may be more economical, especially large capacity sizes. Piston travel, confined to the accumulator, must be calculated with ample margins to store the required fluid.
Gas Valves
Two types of gas valves are available on Series 3000 piston accumulators and gas bottles. Units with 3" thru 6" bores, are offered with a cored gas valve cartridge (ISO-4570-8V1) as standard. All 7" thru 12" bore units are supplied with a heavy-duty, high-pressure, poppet-type gas valve cartridge (L07689000K) as standard.
