High Speed A2FO A2FO28 Long Service Time Low Noise Mini Plunger Pump Piston Bend Axis Hydraulic Pump
Main Application Scenarios
It is widely matched with hydraulic support systems, tunnel boring machines, large loaders, excavators, concrete machinery and mining auxiliary equipment in northwest contracted projects, and is the core power component of open-circuit hydraulic systems in heavy engineering equipment.
Core Technical Features
-
Fixed displacement design: Adopts mature bent-axis piston structure, with stable output flow and no variable failure risks, suitable for constant-pressure and constant-flow hydraulic working scenarios.
-
High pressure resistance: The rated working pressure reaches up to 35MPa, and the peak pressure can withstand instantaneous impact load, meeting the high-load operation requirements of mining and large engineering equipment.
-
Optimized internal damping structure: Built-in precision fixed damping holes and buffer oil circuits, which effectively suppress flow fluctuation, reduce valve body vibration and operating noise, and avoid common faults such as jitter and slow response caused by oil blockage.
-
Strong environmental adaptability: Optimized sealing and shell structure, effectively resists dust, sediment and low-temperature oil viscosity changes, and maintains efficient operation in high-altitude and harsh outdoor working environments all year round.
-
Low failure rate & long service life: Adopts high-precision wear-resistant piston pairs and valve plates, with strong wear resistance and fatigue resistance, reducing frequent maintenance problems of engineering equipment in remote northwest construction sites.
