Small Excavator
The AP2D is a double swash plate variable piston pump, belonging to the category of axial piston pumps. It is specifically designed for use as the main pump or pilot pump in small excavators, adopting open-loop control. With a displacement of 12 cm³/rev, it is suitable for 2.5-5 ton class construction machinery.
Advantages
Compact design: Small size and light weight, suitable for small equipment with limited space.
Efficient power control: Continuous power controller optimizes input power and reduces energy consumption.
Through-shaft expansion: Supports the installation of a third pump or pilot pump to improve system integration.
Multi-condition adaptation: Electro-hydraulic servo regulates flow to adapt to complex loads such as crushing and excavation.
Low noise and long life: Precise fit between piston and cylinder block ensures low noise (<75dB) and a service life of 10,000 hours.
Convenient maintenance: Modular design, with maintenance kits including 10 core components (such as pistons and valve plates) for short replacement cycles.
