Q1: What is the function of the "DR" control?
A: The DR is a Pressure Compensator. It automatically reduces the pump's displacement (destrokes) when the system pressure reaches the preset value. This maintains constant pressure while minimizing energy consumption and heat generation.
Q2: What does the "VPA42N00" suffix indicate?
A: This code defines the mechanical configuration:
V: FKM (Viton) seals for high temperature and chemical resistance.
P: Tapered shaft (1:5) with a parallel key.
A42: Port size code 42 (SAE flange ports with UNC threads).
N00: No through-drive (solid shaft end).
Q3: What is the key difference between this A10VSO71 and the previously mentioned A10VSO45?
A: The primary difference is the displacement size:
A10VSO71: 71 cm³/rev, providing higher flow output (~156 L/min vs ~117 L/min at same speed).
A10VSO45: 45 cm³/rev, smaller size for lower flow requirements.
This model uses a simpler DR pressure control, whereas the previous ones used DFR1 (pressure + load sensing).
Q4: What is the purpose of the L port?
A: The L Port (Case Drain) must be connected directly to the tank. It relieves internal leakage pressure to protect the shaft seal. Maximum allowable backpressure is typically 2 bar.
Q5: Can this pump be used in a closed-loop system?
A: No. The A10VSO DR 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.
