October 7, 2010 - Parker Hannifin introduced 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 for exceptionally fast response, the PV360 is best suited for cranes and lifting equipment, presses, metal forming machines, hydraulic power units (HPUs) and for marine use. In these applications, where the hydraulic system may already be subject to high impact forces, the PV360 - thanks to Parker's ripple chamber technology - produces between 40-60% less pressure and flow pulsation than comparable pumps.
This means that fewer sine waves - capable of loosening hydraulic connections and damaging downstream components - are introduced into the system as added burden; pump noise is also subdued. A second key advantage of the PV360 is its modular design. A wide 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. This permits simple and straightforward in-field conversion, when necessary.
The ease of service afforded by the PV360 is furthermore of great benefit. Metric and SAE mounting interfaces are available and threads/ports can be ordered metric or UNC/UNF, meaning connectors and mounting bolts - even for body and compensator - are available according to local standards around the world. For installation and maintenance, no special tools are needed to alter the pump's configuration, meaning part supply - and once again, field service - present little issue. Finally, all Parker PVplus pumps are 100% through-drive capable and are 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.
Therefore, multiple pump systems can be built with only one drive motor and the maximum displacement of any PVplus pump - also in pump combinations - 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.
