I. Technical Feasibility Analysis

1. Base Parameters of Single Pump:

• Displacement: 250 ml/rev

• Rated Pressure: 35 MPa (Peak Pressure: 45 MPa)

• Maximum Speed: 1,500 rpm

• Maximum Flow Rate: 375 L/min (at 1,500 rpm)

• Power: 219 kW (at 1,500 rpm)

• Torque: 1,391 Nm (at ΔP = 35 MPa)

• Weight: 184 kg

2. Dual-Pump Configuration Logic:

• Parallel Mode: Two A4VSO250 pumps operate in parallel, delivering a total flow rate of up to 750 L/min (at 1,500 rpm), suitable for systems requiring high flow (e.g., large injection molding machines, die-casting machines).

• Series Mode: Custom-designed series configuration enables pressure stacking, though sealing and structural integrity challenges must be addressed. This setup is ideal for ultra-high-pressure applications (e.g., metal forming, pressure testing).

II. Advantages of Dual-Pump Systems

1. Flexible Flow and Pressure Allocation:

• In parallel mode, failure of one pump does not disrupt the other, enhancing system reliability.

• In series mode, staged pressurization reduces energy waste.

2. Modular Design:

• The A4VSO series supports through-shaft drives, allowing integration with gear pumps or auxiliary pumps to streamline system architecture.

3. Control Compatibility:

• Supports multiple control modes, including DR (constant pressure), DFR (pressure-flow compound control), and DFLR (pressure-flow-power compound control), to meet complex operational requirements.

III. Typical Applications

1. Large Injection Molding Machines:

• Parallel dual-pumps provide stable, high flow for rapid injection, ensuring quick hydraulic response.

2. Metallurgical Equipment:

• Series mode meets ultra-high-pressure demands of rolling mills and continuous casting machines.

3. Marine Deck Machinery:

• Parallel design improves system redundancy, withstanding marine vibrations and impacts.

4. Test Bench Systems:

• Precise flow and pressure control simulate extreme conditions for testing.

IV. Selection and Configuration Recommendations

1. Model Expansion:

• For smaller displacement combinations, pair A4VSO125 (125 ml/rev) with A4VSO250 to cover a wider flow range.

2. Control Matching:

• Ensure consistent control modes for both pumps (e.g., both using DFR control) to avoid parameter conflicts.

3. Installation and Maintenance:

• Align axial shafts for parallel pumps to minimize vibration; reinforce sealing for series pumps to prevent leaks.
