A10vo28ED72/52L-Vsc12n00h Hydraulic Piston Pump

Integrated Safety Protection: Built-in pressure relief valve (set to 350 bar) prevents system overpressure damage; anti-cavitation design enhances reliability in low-inlet-pressure conditions (e.g., long-distance oil supply).
Low Noise & Vibration: Optimized swashplate profile and hydraulic damping structure reduce noise to ≤ 80 dB(A) at rated speed, meeting industrial noise standards and improving operator comfort.
Wide Adaptability: Operates reliably in extreme temperatures (-20°C to +90°C) and variable oil viscosities, suitable for both indoor industrial equipment (e.g., injection molding machines) and outdoor mobile machinery (e.g., excavators).
