Q1: What is the function of the "A" control? How does it work?
A: The "A" control is a direct-operated pressure compensator. It uses an internal spring and piston to sense system pressure. When the pressure reaches the preset value (adjusted via the handwheel), the pump automatically de-strokes to near-zero flow, maintaining pressure with minimal energy consumption (holding function). This is ideal for systems with long dwell times.
Q2: What does the "RA01MAO-10" suffix indicate?
A: This code defines the mechanical configuration:
R: Right-hand rotation.
A: Direct-operated pressure control.
01: Pipe threads (G-threads) for suction and pressure ports (not SAE flange).
M: NBR seals, standard for mineral oils.
A: Standard cylindrical shaft.
O: No through-drive (solid shaft).
-10: Zero-stroke pressure range 50–100 bar.
Q3: What is the key difference between PV7 vane pumps and the A4VSO piston pumps?
A: The primary differences are pressure capability and cost:
PV7 (This model): Medium-pressure (100-160 bar), lower cost, quieter operation. Ideal for machine tools, clamping, and low-to-medium power applications.
A4VSO (Previous models): High-pressure (350 bar), higher power density, more robust for heavy-duty applications like presses and construction machinery.
If your system pressure is below 160 bar and noise is a concern, the PV7 is a more economical choice.
Q4: What are the critical installation requirements for this pump?
A:
Suction Conditions: The pump requires a flooded suction. The inlet pressure must be between 0.8 bar (abs) and 2.5 bar to prevent cavitation and seal damage.
Case Drain (L Port): Must be connected directly to the tank with minimal backpressure (max 2 bar).
Port Warning: This model has BSPP (G) threaded ports (01), not SAE flanges. Ensure your piping adapters match this thread type.
Q5: Can this pump be used as a fixed displacement pump?
A: No. The PV7-2X/...A... is inherently a variable displacement pump. It cannot be "locked" into a fixed displacement mode. Its output flow varies automatically based on system pressure to maintain the set pressure limit. For fixed flow, you would need a gear pump or a fixed vane pump.
