Parker Increases Piston Accumulator Bore Size Range to Support Large High Pressure Applications


ROCKFORD, IL - To meet growing market requirements for large accumulators with excellent power density energy and very fast response time, Parker, the global leader in motion and control technologies, now has the capability to produce hydro-pneumatic piston accumulators with a 25-inch inside diameter (ID) bore.

Large bore piston accumulators have increasing application in large power plant valve actuators, die casting, injection molding machines and hydraulic presses, as well as offshore, subsea and deck drilling applications. These applications require a tremendous amount of energy. Hydraulic accumulators provide the needed energy in a smaller package than can be achieved by other means. This is accomplished by designing accumulators that are rated for working pressures in excess of 10,000 psi.

"To support the ongoing demand for large bore accumulators we will continue to invest in our design and manufacturing capabilities," notes Mike Schubert, marketing manager, Hydraulic Accumulator Division. "Parker's ability to design and manufacture increasingly larger hydro-pneumatic piston accumulators is allowing our customers to push the boundaries of what their equipment can accomplish."

The following pressure vessel certifications are available for all Parker piston accumulators:

o ABS - American Bureau of Shipping
o DNV - Det Norske Veritas (E-101 regulations)
o PED - European Pressure Equipment Directive "CE" marking
o ASME - American Society of Mechanical Engineers
o CRN - Canadian Registration Number
o AS1210 - Australian Certification

The Parker piston accumulator capability now includes1.5 to 25-inch bore sizes. All are custom designed to fit a specific application utilizing a total customer-based systems approach that includes application engineering, and worldwide support.
