Hydraulic Pump Nachi PZS Series Variable Volume Piston Pump 70 to 220cm3/rev, 70 to 100cm3/rev 28MPa, 130 to 220cm3/rev 25MPa.
Features Hydraulic Pump Nachi PZS
- High pressure, high reliability
These pumps deliver the perfect combination of high pressure (28MPa{286 kgf/ cm2} maximum) and high reliability. Hydraulic device energy efficiency is ensured because variable volume capabilities provide the means to keep the discharge rate to the desired level. - Low noise, low vibration operation
The semi cylindrical swash plate of the PVS series provides high support and rigidity, making it possible to increase the number of pistons (from nine to 11) and equip optimal valve plates, all of which make low noise operation possible - High reliability, long life.
O-ring seals used for mating surfaces eliminate worries about oil leaks. A spherical valve plate maintains optimal hydraulic pressure balance for stable operation across a wide range and better contamination resistance characteristics. - A wide range of possible applications
In addition to use as a stand alone pump, a PVS Series pump can be combined with another IP pump in a wide range of possible applications.
