Q1: What is the main application difference between A4VSO and A10VSO?
A: A4VSO is a heavy-duty industrial pump designed for 350 bar continuous pressure (vs. A10VSO's typical 280 bar). It features a robust bearing design for high radial loads and is commonly used in metal forming, injection molding, and heavy machinery where high pressure and reliability are critical.
Q2: How does the DR control work on this pump?
A: The DR control is a pressure compensator. Below the set pressure, the pump delivers maximum flow (40 cm³/rev). When system pressure reaches the set point (adjusted via the control cover screw), the swashplate automatically de-strokes to maintain constant pressure, delivering only the flow needed to compensate for leaks. This saves energy compared to a fixed pump with a relief valve.
Q3: What is the recommended drive motor power?
A: At 1500 rpm and 350 bar, the pump requires approximately 35 kW of mechanical input power. It is recommended to use a 37 kW (50 HP) electric motor for safe continuous operation. Always check the torque requirements at your specific operating pressure.
Q4: Can I add a gear pump to the through-drive?
A: No. This specific variant has the code N00, which means no through-drive. The shaft does not protrude from the rear housing to drive an auxiliary pump. If you need a multi-pump configuration (e.g., for a charge pump), you must select a version with a through-drive code (e.g., K01, K02, etc.).
Q5: What are the critical suction conditions?
A: The A4VSO requires good inlet conditions. At 1500 rpm, the inlet pressure should be ≥ 0.8 bar absolute (≈ -0.2 bar gauge) to avoid cavitation. For higher speeds (up to 2600 rpm), a pressurized inlet or a boost pump is mandatory. The optimal viscosity range is 16–160 mm²/s.
