Frequently Asked Questions
Q1: What does "DR" control mean and how does it work?
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?
While the alog 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?
AA10VSO is the specific series designation for this high-pressure version (350 bar peak). The "AA" prefix typically indies a design optimized for higher pressure ratings compared to the standard A10VSO series.
Q4: Why are there two case drain ports?
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?
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.
