Q1: What is the function of the "C" control? How does it differ from the "A" control?
A: The "C" control is a pilot-operated (servo) pressure compensator. It uses a small pilot valve to control a large piston, providing faster and more sensitive response compared to the direct-operated "A" control. When system pressure reaches the set value (adjusted via handwheel), the pump quickly de-strokes to near-zero flow, maintaining pressure with minimal energy loss. It is more precise and has less hysteresis than the "A" type.
Q2: What does the "RE01MC0-16" suffix indicate?
A: This code defines the mechanical configuration and settings:
R: Right-hand rotation.
E: Cylindrical shaft with parallel key (ISO 3019-2).
01: Pipe threads (G-threads) for suction and pressure ports.
M: NBR seals, standard for mineral oils.
C: Pilot-operated pressure controller.
0: Standard version.
-16: Zero-stroke pressure adjustment range up to 160 bar.
Q3: What is the key difference between this model (PV7-1X/25-45) and the previous PV7-1X/25-30?
A: The primary difference is the displacement and flow output:
PV7-1X/25-45 (This model): Larger displacement (45 cm³/rev), higher flow output (~66 L/min), and requires more drive power (~20.5 kW). It is designed for applications needing higher flow at 160 bar.
PV7-1X/25-30 (Previous model): Smaller displacement (30 cm³/rev), lower flow (~43.5 L/min), and lower power requirement (~13.7 kW).
Both share the same robust BG25 frame and 160 bar pressure capability.
Q4: What are the critical installation requirements for this pump?
A:
Suction Conditions: Requires a flooded suction. Inlet pressure must be between 0.8 bar (abs) and 2.5 bar to prevent cavitation.
Case Drain (L Port): Must be connected directly to the tank with minimal backpressure (max 2 bar).
Shaft Warning: The shaft is not designed to handle radial or axial loads. Ensure perfect alignment with the motor using a flexible coupling.
Q5: Can this pump be used as a fixed displacement pump?
A: No. The PV7-1X/...C... is inherently a variable displacement pump. Its output flow automatically reduces to zero when system pressure reaches the set value (pressure-holding function). For fixed flow, you would need a gear pump or a fixed vane pump.
