Product Overview
The Rexroth AP2D18LV1RS7-872-1 (Material Number: R971058721) is a high-performance axial piston pump engineered for mobile and industrial hydraulic systems requiring compact installation envelopes and dependable variable displacement control. As part of the Rexroth AP2D series, this unit utilizes a swashplate-type axial piston rotating group with a bent-axis style displacement mechanism, delivering smooth, infinitely variable flow control proportional to input speed and swashplate angle. The “LV1” control designation indicates a load-sensing / variable displacement regulator configuration, allowing the pump to match system demand and reduce energy losses through standby pressure modulation. With a nominal displacement of 18 cm³/rev, this pump is ideally suited for medium-pressure circuits in mobile machinery and compact industrial power packs where precise flow-on-demand and high power density are critical.

Engineering Features & Advantages
- Precision Performance: Swashplate-type axial piston rotating group delivers high volumetric efficiency and precise flow control across the full displacement range, with minimal pressure ripple and stable operation under varying load conditions.
- Load-Sensing Efficiency: The LV1 control regulator adjusts pump displacement based on system demand, reducing heat generation and power consumption during idle or low-flow phases of the machine cycle.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened piston shoes, precision-ground cylinder bores, and a robust housing designed to withstand shock loads and contaminated environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM Rexroth AP2D18 specifications, ensuring drop-in replacement without modification to mounting flanges, shaft splines, or port connections.
- Compact Power Density: High power-to-weight ratio makes this pump ideal for space-constrained mobile equipment and compact hydraulic power units.
Typical Industrial Applications
This Rexroth AP2D18 axial piston pump is commonly deployed in mobile hydraulics such as mini-excavators, skid-steer loaders, and compact wheel loaders where load-sensing control is essential for fuel efficiency. It is also widely used in industrial power packs for plastic injection molding machines, CNC machine tool hydraulic systems, metallurgical clamping circuits, and marine deck machinery requiring reliable variable-displacement flow control. Additional applications include agricultural equipment, forklift hydraulic systems, and specialized test stands where precise pressure and flow regulation are mandatory.
