LD-A10VSO18 Variable Axial Piston Pump | 18cc 280bar Open Circuit Hydraulic Pump
LD-A10VSO18 Variable Axial Piston Pump | 18cc 280bar Open Circuit Hydraulic P
1. Overview
The LD-A10VSO18 is a compact 18cc/rev variable axial piston pump for open-circuit hydraulic systems. With 280bar continuous pressure and 350bar peak pressure, it delivers high power
density, low noise and long service life.As a direct factory replacement, it achieves 1:1 full interchangeability with original pumps. All units are ISO9001:2015 and SGS certified, with 100% pressure, flow and durability testing to guarantee stable heavy-duty performance.
2. Key Features
Compact & High Power Density: Space-saving structure for limited installation scenarios
280bar High Pressure Resistance: Stable performance under long-term heavy loads
Energy Saving: Adaptive load matching reduces idle power consumption
Low Noise & Vibration: Optimized structure for smooth operation
Multi-Control Compatibility: Full 31-series modular control support
Premium FKM Sealing: High temperature & corrosion resistance for longer lifespan
Tandem Mounting Available: Optional through-drive for multi-pump combination
Strict Quality Assurance: Fully tested and officially certified
3. Control Modes
Supports versatile control options for diverse hydraulic system needs:
DR: Constant pressure control for general hydraulic units
DRG: Remote adjustable pressure for centralized control
DG: Two-point fixed displacement for cyclic equipment
DFR/DFR1: Load sensing energy-saving control
DFLR: Pressure/flow/power triple control against engine overload
ED: Electro-proportional control for precision automated systems
