New range of hydraulic piston
accumulators
The Cylinder Division of Parker Hannifin has introduced a new range of piston accumulators - the AP Series - designed for use in demanding industrial applications.
The Cylinder Division of Parker Hannifin has introduced a new range of piston accumulators - the AP Series - designed for use in demanding industrial applications with working pressures up to 350 bar where high flow rates and short discharge times are critical, for example in die casting and plastic injection moulding where piston speeds of up to 8 m/s are routinely required The new AP Series piston accumulators complement the popular A Series range which is designed for general purpose applications where piston speeds and flow rates are relatively low, such as in power units, pressure maintenance and damping applications

Parker piston accumulators provide a means of regulating and optimising the performance of a hydraulic system and are certified to the new CE approval for pressure vessels, recognised and approved for use - without further local approvals - in all European member states.
They are used in a wide range of industrial applications to supplement pump delivery, reduce energy consumption, protect system components and prolong equipment life, reducing downtime and maintenance requirements.
Their simple and compact design ensures dependable performance with maximum efficiency and service life.

Modular valves ease installation
The IsysNet system is based on a modular construction, using robust quick-fit latching mechanisms that enable valve, I/O and communication modules to be installed on common manifold units in seconds.
Available in a wide variety of lengths, bore sizes from 51 mm to 360 mm, and volumes from 0.1 litres to 300 litres, Parker A Series and AP Series accumulators are particularly suitable for applications where mounting space is critical.
The same fluid capacity can be achieved from different configurations of bore and overall length, providing exceptional versatility for designers.
While the optimum mounting orientation is vertical, angled and horizontal mountings are also acceptable - a major advantage of piston accumulators over bladder types.
To enhance the versatility of Parker piston accumulator ranges, auxiliary gas bottles are available to provide a remote source of pre-charge pressure in situations where accumulator mounting space is restricted.
Auxiliary gas bottles are also CE approved.
Other typical applications for Parker piston accumulators include: machine tools - to maintain pressure and reduce pump size; hydraulic presses, die-casting and plastic injection moulding processes O to provide the high flow rates necessary for rapid pressure rise; piston and diaphragm pumps - to reduce pump pulsations; turbine engines - to supply oil for lubrication; offshore applications - as a source of emergency power for safety and shut-down systems; and paper-making machinery - to maintain guide and backing roller position and pre-load.
