Product Description
PV20 Series Heavy-Duty Variable Piston Pumps for Concrete Mixer Trucks
Product Overview: The PV20 Series (including PV21, PV22, PV23, etc.) is the global industry standard for closed-loop hydraulic drive systems in concrete mixer trucks and heavy-duty mobile machinery. These axial piston variable displacement pumps are specifically engineered to meet the continuous power demands of mixer drums under rigorous transport conditions. Featured models like the PV22 and PV23 are renowned for their exceptional reliability, high power density, and precise Manual Displacement Control (MDC) or Electro-proportional control. Operating at pressures up to 420 Bar, they are the core components for 6-16m³ mixer trucks from leading OEMs like SANY, Zoomlion, and XCMG.
Key Technical Advantages:
Rugged Heavy-Duty Design: Optimized for frequent reversals and long-duration operations common in concrete transport, with reinforced rotating groups for extended service life.
Precise Closed-Loop Control: High energy efficiency with minimal reversal shock, ensuring stable and smooth drum rotation speeds.
High-Pressure Capability: Rated at 21 MPa continuous with peak capabilities up to 42 MPa, handling full-load startups with ease.
Integrated Charge Pump: Features a high-performance built-in charge pump to ensure the main loop remains primed and achieves efficient cooling circulation.
Modular Control Options: Supports MDC (Manual), HD (Hydraulic), and ED (Electric) controls to match varying levels of vehicle automation.
Detailed Models & Parameters:
Core Series: Sauer-Danfoss PV20 Series (Closed Circuit).
Full Model Keywords: PV20, PV21, PV22, PV23, PV24, PV25, PV26, PV27, PV29.
Displacements: From 33cc (PV20) to 227cc (PV27).
Pressure Ratings: Rated at 210 Bar (3000 PSI) continuous; Peak capability up to 420 Bar (6000 PSI).
Max Speed: Up to 2500 – 3500 RPM, depending on displacement size.
Target Applications: Concrete mixer drum drives, paver travel systems, heavy rollers, and rotary drilling rig travel.
