Small Excavator
PV20 is an axial piston pump with a displacement of 20-33cc/rev, a rated pressure of 31.5MPa, and a peak pressure of 35MPa. Its swashplate variable structure enables energy savings through pressure compensation or load-sensing control. Compact and lightweight, it’s easy to install. Optimized design limits noise to ≤70dB(A) for stable operation. Made with high-strength wear-resistant materials, it resists contamination and has a long lifespan. Supporting multiple control modes like manual, hydraulic, and electro-proportional, it offers high adaptability.
