PV2r1 PV2r2 PV2r3 Hydraulische Flügelzellenpumpe für Bagger-Betonmischerpumpe

Q1: What are the core design features of PV2R1/PV2R2/PV2R3 hydraulic vane pumps, and why are they suitable for excavators and concrete mixers?

• High-pressure adaptability: Optimized stator strength and thin-blade design enable a maximum pressure of 21MPa with anti-wear hydraulic oil , meeting the high-pressure demands of excavator boom lifting and concrete mixer drum rotation.
• Low-noise operation: Unique stator transition curve design reduces fluid turbulence and vane impact, resulting in noise levels significantly lower than conventional gear pumps—critical for operator comfort in excavator cabs .
• Compact modular structure: The pump core is easy to disassemble and maintain, allowing quick repairs in construction sites where downtime must be minimized .
• Stable flow output: Minimal pressure pulsation ensures smooth operation of excavator hydraulic cylinders and consistent rotation speed of concrete mixer drums, preventing material segregation .
