PVV Series Fixed Displacement Vane Pump is a compact hydraulic vane pump for equipment that needs steady oil supply and simple maintenance. With multiple displacement sizes from 4 to 28 cm³/rev, it fits hydraulic power packs, machine tools, pressing equipment, test stands and production line systems. The pump offers stable performance under continuous working conditions and is a practical choice for both new hydraulic systems and pump replacement projects.
1. Stable fixed displacement flow: Delivers consistent oil output for hydraulic circuits with predictable flow demand.
2. Good efficiency with reduced wear: Hydraulic unloading of the shaft and vanes helps lower internal stress and supports longer service life.
3. Easy cartridge maintenance: The pump cartridge can be replaced without removing the full pump body, helping reduce downtime during repair.
4. Reliable pressure capability: Suitable for systems requiring continuous pressure performance up to 250 bar and short pressure peaks up to 300 bar.
FAQ
Q1. What is the PVV Series Fixed Displacement Vane Pump used for?
A: The PVV Series Fixed Displacement Vane Pump is used in hydraulic systems that need a steady oil flow at a fixed drive speed. It is a practical choice for hydraulic power units, machine tools, press equipment, clamping systems, oil circulation units, test benches and production line machinery.
Q2. How do I choose the right PVV vane pump size?
A: Start with the required flow, motor speed and working pressure. In a fixed displacement vane pump, a larger displacement normally gives more flow at the same rpm, while a smaller displacement is better for compact systems or lower flow demand.
Q3. Why choose a vane pump instead of a gear pump?
A: A hydraulic vane pump is often selected when the system needs smoother oil delivery, lower pulsation and quieter running. General vane pump references also describe vane pumps as positive displacement pumps that use a rotor and sliding vanes to move fluid through suction and discharge chambers. For clean industrial hydraulic systems where noise, steady flow and service access matter, the PVV fixed displacement vane pump is usually a good fit.
