Frequently Asked Questions (FAQ): Rexroth A2FO Axial Piston Pumps

1. Product Features & Characteristics

Q: What are the key features of the Rexroth A2FO series axial piston pumps?

A: The Rexroth A2FO series is renowned for its robust design and high performance. Key features include:

• Fixed Displacement Design: These are quantitative pumps designed for use in open-circuit hydrostatic transmissions.

• Bent-Axis Design: The axial piston units feature a bent-axis design with a conical piston rotor group, contributing to high efficiency and powerful performance.

• High Power Density: The compact design delivers high power output relative to its size and weight.

• High Overall Efficiency: The pumps are optimized for energy transfer, offering excellent volumetric and hydraulic-mechanical efficiency, which helps reduce operational costs.

• Long Service Life: The drive shaft bearing is designed for high loads, supporting a long service life under demanding conditions. The one-piece piston with a piston ring is also a durable feature.

• Wide Range of Sizes: Available in numerous nominal sizes (e.g., from A2FO10 to A2FO1000) to match specific drive requirements.

2. Applications & Uses

Q: Where are A2FO pumps typically used?

A: A2FO series pumps are versatile and suitable for both mobile and industrial applications. Common uses include:

• Mobile Machinery: Such as excavators, loaders, rollers, and other construction equipment.

• Industrial Equipment: Including metal-forming machines, hydraulic presses, and other stationary industrial machinery requiring reliable hydraulic power.

3. Quality & Selling Points

Q: What are the main selling points and what ensures the quality of these pumps?

A: The main selling points are their reliability, efficiency, and adaptability.

• Proven Design and Durability: The pump housing is designed for sturdiness and long life.

• Economic Efficiency: The high total efficiency sets new standards, leading to lower energy consumption.

• Precision and Control: The output flow is proportional to the drive speed and displacement, ensuring stable performance.

• Quality Assurance: As a product of Bosch Rexroth, a world-renowned leader in drive and control technology, the pumps are manufactured with high precision and undergo strict quality controls.

4. Technical Specifications

Q: What are the key technical parameters?

A: Key specifications vary by model but generally include:

• Nominal Pressure: Typically 315 bar (for sizes 5-200) or 350 bar (for sizes 250-1000).

• Peak Pressure: Can reach up to 400 bar or 450 bar depending on the size.

• Displacement Range: From 0.63 in³/rev to 15.3 in³/rev and beyond across the different models.

5. Service, Warranty, and After-Sales Support

Q: What kind of after-sales service and warranty is available?

A: While specific warranty terms should be confirmed with the supplier or official channels, reputable suppliers generally offer comprehensive support.

• Service Commitment: Suppliers often emphasize customer-centric policies, including reliable pre-sales consultation and after-sales technical support.

• Quality Guarantee: Suppliers typically guarantee that products are 100% genuine and original. Policies like "fake product penalty" are common assurances.

• Return Policy: Non-human factors or product quality issues are usually grounds for return or exchange. It is advised to contact the supplier immediately upon receiving the product if there are any discrepancies.

Important Note: Installation and commissioning of these axial piston units must be performed by qualified personnel to ensure proper operation and maintain warranty conditions.
