Product Overview
The LE-HYDRAULIX LKT0V50+50R/31R-VPA12N00 is a high-performance axial piston variable displacement pump engineered for demanding industrial hydraulic systems. Featuring a tandem configuration (50+50 cm³/rev displacement), this pump utilizes a swashplate design with axial pistons to deliver precise, infinitely variable flow control proportional to input speed and displacement setting. The VPA12N00 control variant provides pressure-compensated operation, automatically adjusting displacement to match system demand while maintaining constant pressure. Manufactured by LE-HYDRAULIX to exacting tolerances, this pump is designed as a direct replacement for Rexroth A10VSO series tandem pumps, offering equivalent performance and dimensional interchangeability for minimal downtime during changeouts.

Engineering Features & Advantages
- Precision Swashplate Control: Axial piston design with hardened swashplate and precision-ground pistons delivers smooth, infinitely variable displacement with minimal pressure ripple and high volumetric efficiency.
- Tandem Configuration Efficiency: Dual 50 cm³/rev pump sections on a common through-drive shaft reduce installation footprint and eliminate the need for separate drive couplings in multi-circuit systems.
- Pressure Compensator (VPA12N00): Automatically adjusts pump displacement to maintain preset system pressure, reducing heat generation and energy consumption during holding or low-demand phases.
- Industrial Reliability: Heavy-duty bearings, case-hardened cylinder barrel, and bronze-filled piston shoes ensure continuous operation under severe industrial duty cycles.
- Direct Fit Replacement: Exact dimensional and functional compatibility with Rexroth A10VSO series tandem pumps, enabling drop-in replacement without piping or mounting modifications.
Typical Industrial Applications
This axial piston variable displacement pump is ideally suited for high-pressure, multi-circuit hydraulic systems including plastic injection molding machines requiring precise pressure holding, metallurgical presses and forging equipment, CNC machine tool hydraulic power units, and heavy-duty construction or marine hydraulic systems where reliable tandem pump performance is
