A11V(L)O Series Variable Displacement Axial Piston Hydraulic Pump — Aftermarket Replacement for Bosch Rexroth A11VO / A11VLO Series

The H-STAR A11V(L)O series is an aftermarket replacement variable displacement axial piston hydraulic pump with swash-plate design, fully compatible with Bosch Rexroth A11VO and A11VLO series (sizes 40-260 cc/rev, Series 1 + Series 40). This pump is designed for hydrostatic drives in open circuits, specifically engineered for heavy-duty mobile and construction machinery applications where high pressure (350 bar) and large displacement are required.

The A11V(L)O is Rexroth's heavy-duty mobile pump line — featuring higher pressure (350/400 bar vs A10VO's 280/350 bar), larger displacement (up to 260 cc vs A10VO's 140 cc), and an optional built-in charging pump (impeller) for high-speed forced suction. It is the main hydraulic pump for concrete pump trucks, large excavators, rotary drilling rigs, road machinery, cranes, and mining equipment.

The A11VO (without "L") is the standard self-priming version. The A11VLO (with "L") features a built-in centrifugal charging pump (impeller) that provides forced suction, prevents cavitation at high speeds, and improves cold-start performance — mandatory for large sizes (190, 260) and heavy-duty applications.

Key features: • High pressure: 350 bar nominal / 400 bar peak (Series 1); 350 bar / 420 bar (Series 40) • Optional built-in charging pump (A11VLO version) for forced suction and anti-cavitation • 100% through-drive: mount additional pumps up to same nominal size • SAE mounting flanges and SAE flanged ports (mobile standard) • Drive shaft can withstand axial AND radial loads • 2 case drain ports • Excellent suction characteristics • Low noise level (swash-plate design is quieter than bent-axis) • Long service life with high-strength cast iron housing • High power density: up to 349 kW (size 260 with charging pump) • Wide range of control options • Externally adjustable power control (even while running) • Short response times

The A11V(L)O series offers a comprehensive range of control devices for mobile applications:

Most common controls for heavy-duty mobile machinery:
* LRDS: Power + pressure cutoff + load sensing — #1 choice for excavator and concrete pump main pumps

* L = Constant power (protects engine from stalling)

R = Regulator
D = Pressure cutoff(protects system from overpressure)
S = Load sensing(delivers only needed flow, saves energy)

DRS: Pressure + load sensing — common for auxiliary pumps and multi-circuit systems
DR: Pressure control — simplest, for constant-pressure applications
EP/EP2: Electric proportional — for fully electronic controlled machinery

Note: Different control types are NOT interchangeable. Please specify your required control type when ordering.

The A11V(L)O series is the mainstream main hydraulic pump for heavy-duty construction machinery, with a primary focus on high-pressure, large-displacement mobile applications:
