Beschreibung
Key Features & Typical Use
Open-circuit operation
A fixed displacement pump for hydrostatic drives in open circuits. Match the inlet conditions and circuit arrangement to the approved technical data.
Bent-axis construction
The axial piston, bent-axis design offers a compact pump layout with high power density for mobile and industrial hydraulic installations.
Speed-dependent flow
For a fixed displacement, output flow varies with drive speed and volumetric efficiency. Confirm your required flow at the intended operating speed.
Configuration matching
Choose the shaft, mounting flange, rotation, seals and service-line ports for the installation. Nominal size alone does not establish compatibility.

A2FO Series — Fixed Displacement Power for Open-Circuit Systems
The A2FO is a fixed displacement pump with an axial piston, bent-axis design. It is intended for hydrostatic drives in open circuits and is used in mobile machinery and industrial hydraulic installations.
Flow depends on displacement, drive speed and volumetric efficiency. Select the pump around your required operating point, then check the shaft, flange, rotation and connections against the installation.
The product’s compact design and drive shaft bearings support its intended mobile and industrial use. Final operating limits must be confirmed for the selected configuration.

Häufig gestellte Fragen
Is the A2FO a fixed displacement pump?
Yes. The A2FO is a fixed displacement axial piston pump with a bent-axis design. Its displacement is not adjusted by a variable displacement control.
Which hydraulic circuit is it intended for?
The current Prance product page specifies open-circuit hydrostatic drives in mobile and industrial applications. Confirm inlet conditions, duty cycle and operating limits before selection.
How do I select the correct A2FO size?
Start with required flow, operating speed, continuous and peak pressure. Then confirm rotation, shaft, mounting flange, ports, fluid and seals against the approved datasheet.
What should I send for a replacement pump inquiry?
Send a clear photograph of the existing nameplate, the full model code if available, mounting dimensions, shaft and port details, operating conditions and required quantity.
Where can I find technical data and the model code?
