The A2FO is a fixed displacement axial piston pump built in a bent-axis design for open-circuit hydraulic systems. It is used when the job calls for steady output, compact installation, and better power density than a simple gear pump layout can usually offer. The structure is more refined, but still practical in real machine use. Not overly complicated. Just more capable where pressure and efficiency matter.
This series is commonly used in both mobile and stationary equipment. The flow stays proportional to speed and displacement, so the hydraulic side remains predictable. That is one reason it fits drive systems, fan drives, winches, auxiliary circuits, and other hydraulic functions where stable output is more important than variable control.
Compared with a more basic pump type, the A2FO sits a little higher in the range. Higher pressure capability. Better efficiency. More compact output for the size. That is usually why customers move to this kind of pump in the first place.

Notes:
Size 5 is a smaller special case in the range, while larger sizes extend well beyond 107 cc/rev for heavier-duty applications.
Size 5 is rated at 315/350 bar, sizes 10 to 200 at 400/450 bar, and larger sizes from 250 to 1000 at 350/400 bar.
Threaded and SAE-style service line arrangements exist within the series, depending on the selected model code.

How It Works
The A2FO works with a bent-axis axial piston rotary group. When the shaft turns, the piston group rotates and creates the pumping action through the angled drive arrangement. Oil is drawn in at the inlet side and pushed out through the pressure port as the pistons cycle. That is the basic idea. No variable control block inside. No displacement adjustment during running. Fixed means fixed.
Because the flow is proportional to speed and displacement, system output is easy to calculate and easy to match. That makes the A2FO a practical choice for circuits where the machine needs dependable hydraulic delivery without adding extra control complexity into the pump itself.
Model Range
Compact Sizes
A2FO10 / A2FO12 / A2FO16
Small models for tight spaces. Good for auxiliary tasks or lighter loads, still keeps up with high-speed needs.
Mid-Range Sizes
A2FO23 / A2FO28 / A2FO32 / A2FO45
A practical range most users choose. Delivers more flow but stays compact, often picked for versatile machine setups.
Higher Output Sizes
A2FO56 / A2FO63 / A2FO80 / A2FO90 / A2FO107
For systems handling heavier demands. These pumps are strong performers in open-circuit setups, built for serious tasks.
Extended Sizes
A2FO125 / A2FO160 / A2FO180 / A2FO200 and above
Models for large-scale projects. Needs vary here-best to confirm installation and operating requirements first.
Applications & Industries
The A2FO is used where a machine needs a fixed-displacement high-pressure pump with a compact body and solid efficiency. It fits both mobile equipment and stationary hydraulic systems, so the application range is fairly wide. Not limited to one machine type.
Works well in open-circuit hydraulic systems on equipment that needs reliable fixed output and strong pressure capability.
A good fit for tractors, attachments, and support circuits where durability and installation space both matter.
Used in lifting, winch, and drive-related hydraulic functions where a fixed piston pump makes more sense than a variable unit.
Also suitable for stationary hydraulic packs and process equipment that need predictable output and a compact high-pressure pump.
Often selected for auxiliary hydraulic functions that need consistent flow without extra control complexity.

FAQ Display Content
1) What kind of pump is the A2FO?
It is a fixed displacement axial piston pump with a bent-axis design for open-circuit systems.
2) Is the A2FO a variable pump?
No. The A2FO is a fixed pump. Flow changes with speed, not with on-pump displacement control.
3) What pressure can the A2FO handle?
That depends on size. Size 5 is in the 315/350 bar class. Sizes 10 to 200 are in the 400/450 bar class. Larger sizes from 250 upward are typically in the 350/400 bar class.
4) What sizes are available?
The A2FO series covers a broad range, starting from small sizes like 5, 10, 12, 16 and extending up to 1000 cc/rev in the larger end of the family.
5) What shaft and flange options can be supplied?
Different versions are available, including splined shaft, parallel keyed shaft, and different 4-hole or 8-hole mounting flanges, depending on size and configuration.
6) Can you provide different port layouts?
Yes. Depending on the selected model, the series can be supplied with threaded ports or SAE-style flange ports, with side or rear arrangements.
7) What hydraulic fluid can it use?
Mineral oil is standard. Some other hydraulic fluids can also be used depending on size and bearing or seal configuration. That part should be checked before order.
8) What do you need before quoting?
Please send the size, shaft type, flange type, port style, rotation, quantity, application, and destination country. If you have an old code or a nameplate photo, that helps a lot.
