Rexroth A7V Series Pump | A7V58, A7V500, A7V1000 | 400 Bar Bent Axis Piston Pump

Rexroth A7V Series Heavy-Duty Bent Axis Variable Piston Pump

Product Overview: The Rexroth A7V series is the industry-recognized benchmark for Bent Axis variable piston pumps. This series spans from the core 58cc (A7V58) to the massive 1000cc (A7V1000) displacement. Featuring a unique bent-axis rotating group design, the A7V series delivers superior self-priming ability and volumetric efficiency compared to conventional swashplate pumps. Whether in the A7V500EL with electronic regulation or the A7V1000HD for heavy-duty systems, Linde provides peak dynamic power up to 400 Bar, making it the heart of large industrial presses and marine engineering.

Key Technical Advantages:

• Superior Bent Axis Geometry: This architecture allows for a larger swivel angle, enabling a wider displacement range and higher maximum speeds, particularly excelling in suction-inlet conditions.

• Heavy-Duty High-Pressure Reliability: Rated at 350 Bar (5100 PSI) with peak capabilities reaching 400 Bar, utilizing a high-strength spherical valve plate to ensure sealing integrity under high-frequency shock loading.

• Versatile Precision Controls (MA/HD/EL/LV):

  • HD Control (A7V1000HD): Features high-pressure related hydraulic control for precise linear flow output relative to system pressure.

  • EL Electronic Control (A7V500EL5.1): Supports electro-proportional regulation via electrical signals for stepless displacement modulation in digital production.

  • LV Constant Power Control: Models like the A7V500LV5.0 use a power limiter to automatically adjust displacement, preventing motor or engine overload.

• Extended Service Life: Reinforced bearing supports and wear-resistant valve plate materials ensure durability in grueling 24/7 industrial duty cycles.
