A7V160LV1RPF00 Axial Piston Pump | 35MPa Rexroth Interchangeable

Product Overview

The A7V series bent-axis axial piston variable pumps are engineered for hydrostatic transmissions in open hydraulic circuits. Output flow is proportional to drive speed and geometric displacement, enabling stepless flow regulation at constant rotational speed. These pumps offer 100% drop-in interchangeability with Rexroth A7VO series units of the same specification, with identical mounting dimensions, port positions and shaft profiles — no modification to equipment circuits or mounting flanges is required. Every unit undergoes full-pressure, full-speed simulated working condition testing before delivery, with strict verification of volumetric efficiency, pressure pulsation and operational reliability to meet heavy-duty high-pressure performance requirements.

Key Technical Advantages

1. Spherical Valve Plate Efficiency: The rotor and valve plate feature a spherical distribution design with self-centering capability during operation, reducing peripheral linear speed of the piston assembly. Volumetric efficiency reaches ≥92%, with stable internal leakage control even under continuous high pressure.
2. Heavy-duty Bearings with Hydrostatic Unloading: Equipped with high-load roller bearings and hydrostatic unloading structure to counteract most axial thrust, significantly extending bearing service life under high-pressure conditions and reducing mechanical wear.
3. 100% Drop-in Interchangeability: Mounting flanges, port locations, shaft dimensions and control interfaces fully match Rexroth A7VO series pumps. Direct replacement eliminates the need for equipment modification, minimizing downtime and replacement cost.
4. Full Working Condition Factory Testing: Each pump is tested under rated pressure, peak pressure and rated speed before delivery, with inspection of volumetric efficiency, pressure pulsation, noise and leakage to ensure performance meets original factory standards.
5. Low-noise Optimization: Improved valve plate porting geometry and housing damping structure effectively suppress fluid pulsation and structural vibration, reducing operating noise by 5 dB(A) compared to conventional bent-axis pumps.
6. Wide Fluid Compatibility: Compatible with mineral anti-wear hydraulic oil, water-glycol and phosphate ester fire-resistant fluids, suitable for special working conditions in metallurgy and mining industries.

Application Areas

• Construction Machinery: Static pressure pile drivers, concrete pump trucks, crawler excavators, heavy-duty cranes
• Metallurgical Equipment: Rolling mill hydraulic systems, steelmaking tilting mechanisms, metallurgical production line power units
• Mining Machinery: Roadheaders, hydraulic support systems, mine hoisting winches
• Industrial Equipment: Heavy hydraulic test machines, forging presses, ceramic pressing machines
• Marine Deck Machinery: Steering gear systems, windlasses, hydraulic winches

Expert Maintenance Tips

1. Installation Alignment: Connect the pump shaft to the prime mover with a flexible coupling, controlling coaxiality deviation within 0.05 mm. Tighten mounting flange bolts evenly in diagonal sequence to avoid additional radial stress on the pump housing.
2. Fluid & Cleanliness: ISO VG46 anti-wear hydraulic oil is recommended, with oil cleanliness no lower than NAS grade 8. The system shall be equipped with a return filter of ≥10μm filtration accuracy. Operating oil temperature shall be maintained at 30~80℃, with a short-term maximum of 90℃.
3. First Commissioning & Running-in: Fill the pump housing with clean hydraulic oil before first start to remove trapped air. Run under no-load condition for 15~30 minutes, then gradually increase pressure to nominal level to complete the running-in cycle.
4. Periodic Maintenance Schedule: Check oil contamination and external leakage every 2000 operating hours. Replace shaft seals and control cavity seals every 5000 operating hours, and inspect valve plate wear condition.
5. Operation Cautions: Do not run the pump without oil. Do not operate continuously at peak pressure for more than 1 minute per cycle. Avoid frequent impact loads to maximize service life.
