Q1: What is the function of the "DFR1" control?
A: The DFR1 is a combined Pressure and Flow Controller. It provides two key functions:
Pressure Limiting: Acts as a pressure compensator, destrokeing the pump when system pressure reaches the set value.
Load Sensing (Flow Control): Automatically adjusts displacement to maintain a constant pressure differential (Δp) across a downstream orifice, providing load-independent flow control for improved energy efficiency.
Q2: What does the "VPB12N00" suffix indicate?
A: This code defines the mechanical configuration:
V: FKM (Viton) seals, offering superior chemical and temperature resistance.
P: Tapered shaft (1:5) with a parallel key.
B12: Port size code 12 (metric threads).
N00: No through-drive (solid shaft end, cannot mount additional pumps on the shaft).
Q3: What is the key difference between this A10VSO45 and the previously mentioned A10VSO28?
A: The primary difference is the displacement size:
A10VSO45: 45 cm³/rev, providing higher flow output (~117 L/min vs ~84 L/min at same speed).
A10VSO28: 28 cm³/rev, smaller size for lower flow requirements.
Both share the same DFR1 control type and Series 31 design.
Q4: What are the X and L ports used for?
A:
X Port (Control): Load-Sensing (LS) Feedback. It connects to the downstream system to sense the load pressure, allowing the pump to adjust its displacement to maintain the set Δp.
L Port (Case Drain): Must be connected directly to the tank. It relieves internal leakage pressure to protect the shaft seal (max backpressure typically 2 bar).
Q5: Can this pump be used in a closed-loop system?
A: No. The A10VSO DFR1 is designed exclusively for open-circuit applications (pump → valve → actuator → tank). For closed-loop hydrostatic transmissions, you would need an A4VG or A2FM series unit.
