FAQ - Frequently Asked Questions

Q1: What does "DR" control mean and how does it work?

A:​ DR​ stands for Pressure Control. The pump operates in "load-sensing" mode for pressure:

  • Below set pressure: The pump delivers maximum flow (140 cm³/rev).

  • At set pressure: The swashplate de-strokes automatically to maintain a constant pressure, only delivering the flow needed to compensate for leaks. This saves energy compared to a fixed pump with a relief valve.

Q2: Can this pump run at 3000 rpm?

A:​ While the catalog may list a maximum speed of 3000 rpm, the standard nominal speed for Size 140 is 1800 rpm. Running at 3000 rpm requires excellent suction conditions (pressurized inlet > 0.8 bar abs) and may reduce service life. Always check the performance curves for your specific viscosity.

Q3: What is the difference between AA10VSO and A10VSO?

A:​ AA10VSO​ is the specific series designation for this high-pressure version (350 bar peak). The "AA" prefix typically indicates a design optimized for higher pressure ratings compared to the standard A10VSO series.

Q4: Why are there two case drain ports?

A:​ The pump has two case drain ports​ (leakage oil ports) to provide flexibility in plumbing. You only need to use one​ of them. The second port must be plugged. This allows you to choose the most convenient side for routing the case drain line back to the tank.

Q5: Can I use this pump with a diesel engine drive?

A:​ Yes, it is commonly used in mobile machinery. Ensure the rotation direction is correct​ (Clockwise 'R'). Diesel engines often have SAE flywheel housings, so you may need an adapter flange. Also, ensure the engine's torsional vibration characteristics are within pump limits.
