Product Description
Premium factory-direct aftermarket Rexroth A1VO018 Series Axial Piston Variable Displacement Pump (and complete rotary group repair kits), precision-manufactured as a 100% plug-and-play interchangeable drop-in replacement for OEM Bosch Rexroth A1VO018. Engineered specifically to replace inefficiency in classical fixed-displacement gear pumps, this compact $18\text{ cm}^3/\text{rev}$ fluid power powerhouse delivers rapid load-sensing response and exceptional volumetric efficiency for compact agricultural machinery, municipal mobile platforms, and high-duty industrial power packs. Built using upgraded nodular ductile iron housings and bimetallic sintered cylinder groups, our A1VO018 pump flawlessly sustains continuous operating pressures up to 250 bar and intermittent peak pressures up to 280 bar
Key Technical Highlights
-
100% Flawless OEM Dimensional Alignment: Reverse-engineered strictly to original Bosch Rexroth blueprint constraints. Identical SAE / DIN mounting flanges, splined/keyed drive shafts, and high-pressure porting layouts guarantee direct bolt-on swap-out with zero pipe rerouting.
-
Pre-Calibrated Load-Sensing (DRS / ED) Control Valves: The integrated load-sensing and pressure compensator control valves undergo automated dynamic flow calibration on our test rigs. They react within milliseconds to load variation, eliminating hydraulic latency, oil shearing, and engine lugging.
-
High-Density Vacuum-Sintered Rotary Group: Features bimetallic cylinder barrels with vacuum-sintered bronze alloy layers paired with induction-hardened alloy pistons . This micro-lapped friction pair reduces internal bypass leakage, keeping system oil cool during long duty cycles.

FAQ
Q1: Many aftermarket compact variable pumps suffer from sluggish load-sensing response times, causing actuator hesitation. How does your A1VO018 handle dynamic LS response?
A: Sluggish response is caused by imprecise spool clearance in the compensator block. At Guangdong Haozheng, our A1VO018 DRS control spools are CNC micro-ground and lap-fitted to micro-metric tolerances ($<0.002\text{ mm}$). Every pump is dynamic-tested on our automated flow benches to mirror exact OEM stroke and destroke curves, ensuring immediate fluid delivery the millisecond your control valve opens.
Q2: Does your A1VO018 replacement pump support both complete assembly swap-out and internal rotary group rebuilds for existing Rexroth casings?
A: Yes, absolutely. We supply both 100% complete A1VO018 pump assemblies and individual rotary rebuild kits (cylinder blocks, pistons, valve plates, drive shafts). Every internal component is micro-lapped to be 100% interchangeable with genuine Rexroth parts, allowing your maintenance team to either swap the whole unit or rebuild on-site with total confidence.
