The A7VO 28LR/63R-NZB01 hydraulic pump belongs to the A7VO series, which is known for its advanced design and efficient operation.
It features a variable displacement axial piston pump, which means it can adjust the output flow rate according to the system requirements. This versatility allows it to adapt to different load conditions, providing optimal performance and energy efficiency.
The displacement of this pump is 28cc/rev, indicating the volume of fluid it can deliver in one revolution. This displacement size makes it suitable for medium-duty applications that require a moderate flow rate. The 63R-NZB01 designation signifies the mounting style and connection type of the pump. In this case, it has a SAE B 2-bolt flange mounting and a SAE 4-bolt flange outlet port. These standardized connections facilitate easy installation and integration into hydraulic systems.
The A7VO 28LR/63R-NZB01 pump operates with a maximum pressure rating of up to 400 bar (5800 psi). This high-pressure capability makes it suitable for demanding applications that require reliable performance under heavy loads. Additionally, it offers a continuous pressure rating of 350 bar (5075 psi), allowing it to sustain high-pressure operation over extended periods.
To ensure smooth and efficient operation, the pump incorporates a precision-controlled servo piston. This piston is responsible for adjusting the displacement and maintaining the desired flow rate. The servo piston design enables precise control and responsiveness, ensuring optimal performance and load handling capabilities.
The A7VO 28LR/63R-NZB01 hydraulic pump utilizes a swashplate design. The swashplate converts the rotary motion of the drive shaft into axial piston reciprocating motion, which generates the hydraulic flow. This design offers high efficiency, low noise levels, and excellent reliability. It also allows for precise control of the displacement, enabling the pump to meet varying system demands accurately.
This pump is designed for long service life and durability.
It incorporates high-quality materials and precise manufacturing techniques to ensure robustness and resistance to wear. The components are engineered to withstand challenging operating conditions and provide reliable performance in demanding environments.
Furthermore, the A7VO 28LR/63R-NZB01 hydraulic pump is compatible with a wide range of hydraulic fluids, including mineral oils, biodegradable fluids, and water glycols. This versatility allows for flexibility in choosing the appropriate fluid for specific applications.
In terms of maintenance, the pump is designed to be easily serviceable. It features accessible service points and straightforward disassembly, allowing for efficient inspection, repair, and replacement of components when necessary. Regular maintenance and proper care will help maximize the pump's lifespan and performance.
