Guangdong Haozheng Hydraulic Equipment Co., Ltd. specializes in manufacturing high-efficiency Rexroth A2FO series fixed displacement axial piston pumps. Specifically engineered for hydrostatic drives in open-circuit configurations, the A2FO series utilizes a well-proven bent-axis design. By optimizing internal flow kinetics and fluid port positioning, it delivers high operational efficiency, robust self-priming speeds, long service life, and an exceptionally compact mounting footprint.

As an established global B2B hydraulic supply partner, Haozheng supplies complete A2FO pump assemblies and precision-machined internal repair components with 100% dimensional and functional interchangeability with original Bosch Rexroth units. To ensure immediate plug-and-play reliability and eliminate operational anomalies in the field, every single pump is rigorously calibrated and load-tested on our advanced hydraulic test benches before global dispatch.

Frequently Asked Questions (FAQ)
Q1: What is the primary operational difference between Rexroth A2FO and A2F series? A: While both feature a bent-axis structure, the A2FO is engineered exclusively as a fixed displacement pump for open-circuit setups, featuring optimized internal fluid passages to maximize suction limits. The A2F, however, is a dual-function unit that can be deployed as either a constant pump or a hydraulic motor depending on its configuration and port layout.
Q2: Why is the choice of shaft rotation (Clockwise vs. Counter-Clockwise) critical for A2FO truck pumps? A: Commercial truck power take-offs (PTOs) turn in specific directions depending on the gearbox design. Running an A2FO pump in the opposite direction of its engineered rotation (indicated by ‘R’ for CW or ‘L’ for CCW in the model code) will instantly cause severe internal friction, seal damage, and rapid component failure. Always verify your PTO rotation before ordering.
Q3: What are the best practices for installing a new A2FO bent-axis pump on a truck PTO? A: To avoid catastrophic fluid starvation upon engagement, you must completely fill the pump housing with clean hydraulic oil through the highest case drain port before initial operation. Additionally, verify that the suction line diameter is sufficiently wide and entirely free of air leaks to avoid cavitation at high diesel engine speeds.
