Product Description
Rexroth A8VO & A8V Series Double Axial Piston Variable Pumps
Product Overview: The Rexroth A8VO and A8V series are high-performance double axial piston variable pumps specifically engineered for multi-circuit Open Circuit hydraulic systems. As the primary hydraulic pump for excavators, rotary drilling rigs, and various mobile machinery, the A8VO series provides exceptional power density by integrating two rotating groups within a single housing. Covering a displacement range from 28cc to 140cc and equipped with advanced LAOKH constant power control, these pumps ensure a perfect match with engine power for smooth and efficient compound movements under heavy-duty operations.
Key Technical Advantages:
Integrated Double Pump Design: The A8VO series combines two high-performance piston units within one housing. Driven via a gear splitter or direct drive, it provides synchronized flow while optimizing installation space in large machinery.
Intelligent Power Regulation (LAOKH): The A8VO107LAOKH3/63R1-NZGO5F001-S model features a sophisticated regulator integrating constant power control, hydraulic pilot adjustment, and cross-sensing. This ensures the combined power of both pumps does not exceed engine capacity, preventing stalls.
Heavy-Duty High-Pressure Performance: Supports a rated pressure of 350 Bar and peak cycles up to 400 Bar. Reinforced rotating groups and swashplate supports guarantee extended service life under continuous heavy-load cycles.
Full Displacement Range: Available in A8V28, A8V55, A8V58, A8V80, A8V107 and the advanced A8VO55, A8VO80, A8VO107, A8VO140 models, meeting power requirements from medium to ultra-large scale machinery.
