Product Overview
The Rexroth AP2D18LV1RS7-920-2-35 (also referenced as EC123S9201-2) is a variable displacement axial piston pump engineered for mobile and industrial hydraulic systems requiring compact, high-pressure power delivery. Operating on the proven swashplate principle, this pump features an 18 cm³/rev nominal displacement and a load-sensing (LS) control with pressure compensation, allowing it to modulate output flow in direct response to system demand. This results in significant energy savings, reduced heat generation, and precise actuator control. The AP2D series is widely recognized for its robust rotating group, integrated auxiliary pump option, and suitability for closed-center hydraulic circuits in mobile machinery and compact industrial power packs.

Engineering Features & Advantages
- Precision Performance: The axial piston rotating group with hardened swashplate and precision-ground pistons delivers high volumetric efficiency and stable flow across the entire pressure range, minimizing internal leakage and maintaining consistent actuator speed.
- Load-Sensing Efficiency: The LS control matches pump output to actual system demand, reducing throttling losses, lowering oil temperature, and cutting fuel or electrical power consumption in variable-load applications.
- Compact High-Power Density: The AP2D18 frame size provides substantial pressure capability in a small envelope, ideal for space-constrained mobile equipment and compact power units.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with robust bearings, durable valve plate, and contamination-tolerant design consistent with Rexroth’s mobile hydraulics standards.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM Rexroth AP2D18 specifications, ensuring drop-in replacement without modification to mounting, shaft, or port interfaces.
Typical Industrial Applications
This pump is commonly specified in mobile hydraulic systems such as mini and compact excavators, skid-steer loaders, and agricultural machinery
