A17FO is a fixed displacement axial piston pump in bent-axis design for open-circuit use. The main thing about this series is pretty simple: it is built for machines that want stable output, compact installation, and real working pressure without going to an oversized pump body. In actual use, you see it a lot on truck hydraulics, PTO-driven systems, mobile equipment, and other setups where space is tight and the pump still has to work hard.
Compared with more basic pump types, this series is usually chosen when the user wants better efficiency, smoother running, and stronger pressure capability in a smaller package. The bent-axis layout helps with power density, and the rotary group design is one reason these pumps are often used in tougher duty cycles instead of lighter intermittent work only.
Another practical point is installation. This series was laid out for direct mounting on truck PTO-type interfaces, with ISO 7653 flange format and a splined shaft arrangement similar to DIN ISO 14. So for vehicle hydraulics and compact power packs, it is a very workable format.
Key Features & Benefits
Delivers flow as demand changes
Instead of supplying unnecessary output all the time, the variable displacement concept allows the system to respond more closely to actual working requirements.
Pressure capability for tough applications
Rated at 350 bar nominal and 400 bar peak, the pump is suited to heavy-duty hydraulic service.
Fits a wide range of machine sizes
The broad displacement spread gives builders more flexibility when selecting a pump for either compact equipment or higher-flow systems.
Control options that support better tuning
Different control choices allow the machine to be set up around real operating behavior rather than a simple one-mode approach.
Load-sensing versions for variable loads
Where system load changes during operation, load-sensing configurations help keep flow response more consistent.
Through-drive design for multi-pump layouts
This option supports tandem pump arrangements without the added complexity of a separate splitter gearbox.
Charge-pump options for more demanding conditions
Large-frame charge-pump versions improve inlet support when the application places greater demands on filling performance.

Technical values above are based on the standard size range shown for the A17FO series, including displacement, rated speed, limiting speed, flow, and approximate mass, with port sizes taken from the dimension pages for each frame size.
A few working limits worth checking before order: service-line nominal pressure is 350 bar, maximum pressure is 400 bar, suction-side minimum pressure is 0.8 bar absolute, and recommended oil cleanliness is at least ISO 4406 20/18/15.

How It Works
This is a fixed displacement bent-axis piston pump. Once the shaft turns, the piston group rotates with the cylinder block and creates suction on the inlet side and pressure flow on the outlet side. Because displacement is fixed, the pump flow mainly follows speed. Faster in, more flow out. That part is very direct.
The bent-axis layout is one reason the pump stays compact while still handling higher working pressure. The torque goes into the rotary group, hydraulic oil is pulled through the suction port, then pushed to the pressure line as the piston chambers cycle through intake and discharge. No fancy story here. It is a fixed pump, so the job is stable flow, not variable control.
On truck and mobile hydraulic systems, that makes sense. PTO speed changes, engine speed changes, the pump output follows. So when customers choose A17FO, they are usually looking for a fixed high-pressure pump that is compact and easier to mount, not a variable unit.
Model Range
A17FO23 / A17FO32
Smaller frames for compact hydraulic circuits, lighter truck functions, and installations where space is tight and hose routing is awkward. Service and suction ports stay smaller here too.
A17FO45 / A17FO63
These are often the middle-ground sizes. Enough flow for many mobile hydraulic jobs without jumping straight to the larger frames. Good fit for truck attachments, tipping systems, and compact auxiliary circuits.
A17FO80 / A17FO107
Higher-flow sizes for heavier-duty mobile systems and truck hydraulics where the PTO-driven circuit needs more output. Larger service and suction ports are used on these frames.
Applications & Industries
Truck Hydraulics
This is one of the more natural fits for A17FO. Tipper trucks, hook lifts, cranes, mixers, refuse vehicles, road service bodies. Anywhere a PTO-driven hydraulic circuit needs a compact high-pressure fixed pump.
Construction Equipment
Used on mobile hydraulic power packs and support circuits where stable fixed flow is preferred over variable displacement complexity.
Agricultural Machinery
Can be used on trailers, field service units, and hydraulic support equipment where compact installation and reliable fixed output matter.
Material Handling
Suitable for certain lifting, moving, and auxiliary hydraulic systems where a rugged open-circuit pump makes more sense than a lighter-duty alternative.
Municipal and Utility Vehicles
Sweepers, service trucks, recovery units, and other bodybuilder applications where space around the PTO area is never generous.
Mining Equipment
A17FO is ideal for loaders, drills, and underground systems, offering high pressure, stable flow, and compact installation.

FAQ
1) Is A17FO a fixed pump or a variable pump?
A17FO belongs to the fixed-displacement side. In practical terms, that means flow rises and falls with rpm; the pump does not vary output by itself. If adjustable output is a key requirement, most buyers would look elsewhere.
2) Can you match my old truck pump?
Usually yes, but we don't like guessing on replacement jobs. We'll need the displacement, shaft form, flange pattern, ports, direction of rotation, and where the unit is mounted. If you can send a tag photo, that helps a lot.
3) What pressure can this series handle?
A good starting point is 350 bar for continuous use and 400 bar for peak load. But if your application involves hard impact loading, frequent spikes, or long high-pressure holding time, selection should be based on the real working cycle, not just the catalog figure.
4) What sizes are available?
Typical options are 23, 32, 45, 63, 80, and 107 cc/rev. Buyers should note that different sizes do not simply change displacement; they may also differ in port thread, speed capability, and overall dimensions.
5) Is it mainly for truck PTO systems?
Yes, that's one of the common use cases. The mounting style suits PTO-driven hydraulic setups well, so the pump is often seen on trucks and other mobile equipment rather than on fixed industrial systems.
6) Does this pump need a case drain line?
The standard arrangement does not require a separate case drain. That makes installation cleaner on many builds. Still, hose routing should always be checked against the actual machine design before final assembly.
7) What oil cleanliness should be kept?
Oil cleanliness is not something to leave vague on a piston pump. A minimum level of ISO 4406 20/18/15 is typically recommended. In hotter running conditions, tighter control is usually the safer approach.
8) Is it better than a gear pump?
That depends on the job. For basic systems where budget comes first, a gear pump can still be the practical answer. For higher pressure demands and a more compact high-power layout, A17FO is often the better fit.
