The Core Advantages of Variable Plunger Pumps Empowering ALT Backhoe Loaders

The variable plunger pump, a key component of the hydraulic system in ALT's new generation of backhoe loaders, demonstrates significant technical advantages with its unique structure.

It offers higher working pressure (up to 35MPa and above) and volumetric efficiency (>95%) than gear pumps, maintaining stable flow output even under complex working conditions, and fully meets the demands of heavy-load operations in backhoe loaders. It automatically adjusts flow and pressure according to load requirements, improving the coordination of compound actions by over 30%, especially showcasing precise control capabilities in synchronous digging and rotating operations. This system is 15%-20% more energy-efficient than traditional systems, effectively reducing fuel consumption. Tests proved that the hydraulic system with variable plunger pumps extends the lifespan of ALT equipment to 8000 hours and doubles maintenance intervals, significantly lowering life cycle costs.
