Parker Hannifin Corp., Marysville, Ohio, has introduced a new PVplus axial piston pump, the PV360. A variable displacement 360 cc/rev pump, the PV360 can address a wide range of heavy-duty mobile and industrial applications with operating pressures up to 5,000 psi (350 bar).
Featuring a large servo piston, the PV360 is best suited for cranes and lifting equipment, presses, metal forming machines, hydraulic power units, and marine use. The pump produces between 40 and 60 percent less pressure and flow pulsation than comparable pumps, according to Parker Hannifin. This means that fewer sine waves are introduced into the system as added burden and pump noise is subdued.
A variety of compensator options are offered, including standard pressure, remote pressure, load sensing and horsepower. Pilot valves can also be directly mounted without any piping.
Metric and SAE mounting interfaces are available and threads/ports can be ordered in metric or UNC/UNF so connectors and mounting bolts are available according to local standards around the world. For installation and maintenance, no special tools are needed to alter the pump's configuration.
All Parker PVplus pumps are through-drive capable and equipped with an easily accessible displacement adjustment screw. In double configurations, both pumps can be used at full flow and nominal pressure at the same time. Multiple pump systems can be built with only one drive motor and the maximum displacement of any PVplus pump can be adjusted or modified at any time. In addition to the new PV360, Parker's PVplus pump series includes 16, 20, 23, 28, 32, 40, 46, 63, 80, 92, 140, 180 and 270cc displacement models.
