LR2: Basic constant power (horsepower) control – follows a hyperbolic P×Q = const curve to protect the drive motor from overload. Power limiting start point is set mechanically.
LR2G: Same hyperbolic constant power characteristic + remote pressure limiting (pressure cut-off) via an external pilot relief valve connected to the XD port. The pressure at which the pump cuts displacement back (pressure override) is determined by the external pilot valve setting + internal differential (~20 bar). This allows remote adjustment of the max system pressure without opening the pump.
Connect a pilot relief valve (DB …-5X/… type recommended) between the LR2G's XD port and tank. The pilot valve's cracking pressure determines the pressure limiting setpoint. The XD port must never be blocked. When system pressure reaches (pilot valve setting + ~20 bar internal differential), the LR2G forces the pump to stroke down.
Yes. The PPB code indicates through‑drive capability. An A4VSO (same or smaller) or compatible gear pump can be flange-mounted on the rear. N00 = no auxiliary gear pump pre-fitted, through-drive shaft is present.
Yes, strongly recommended. LR2G provides power limiting and remote pressure cut-off under normal conditions but has response time. A system safety relief valve (e.g. DB type, set slightly above max LR2G setpoint + margin) protects against spikes from thermal expansion or pilot valve failure.
Maintain ISO 4406 18/16/13 (NAS 1638 Class 8 -9) minimum using a return-line filter β₁₀ ≥ 200 (10 µm nominal). Contamination is the primary cause of A4VSO premature wear.
No. A4VSO is an industrial open-circuit pump. Mobile wheel loaders and excavators typically use A4VG (closed circuit) or A11VO (open axial) as travel/main pumps. A4VSO with LR2G may be used in loader factory test benches, auxiliary stationary HPUs, or mine-site industrial hydraulic stations, not as a direct OEM travel pump replacement.
