Product Description
Nachi PVD-1B Series Hydraulic Main Pumps for Mini Excavators
Product Overview: The Nachi PVD-1B Series is the premier choice for mini excavator hydraulic systems worldwide. Featuring a highly compact integrated design, this series houses two variable axial piston pumps and one fixed gear pump within a single housing. Featured models like the PVD-1B-32P-11G5-4665C and PVD-1B-34P-11G5-4665A are custom-engineered for 1.5-ton to 4-ton excavators, providing 100% compatibility for leading brands such as Kubota, Komatsu, Yanmar, and Hitachi. Its exceptional reliability ensures high-efficiency operation for mini-machinery under demanding job site conditions.
Key Technical Advantages:
Triple Pump Integration: Delivers three independent hydraulic circuits via a single-shaft drive. The dual main pumps power digging and travel, while the rear gear pump (e.g., 11G5) manages pilot control or auxiliary functions, optimizing space.
High-Response Constant Power Control: Equipped with precision pressure compensation and power modulation, it adjusts flow in real-time based on load, preventing engine stalls and significantly reducing fuel consumption.
Exceptional Pressure Durability: Rated for continuous operation at 21-25 MPa (3000-3600 PSI). Core rotating groups (pistons, slippers) utilize special anti-wear alloys to ensure long service life under high-intensity digging pressures.
Quiet Operational Profile: The optimized valve plate design not only improves volumetric efficiency but also suppresses hydraulic pulsation and noise, enhancing operator comfort.
Precise Synchronization: Superior flow synchronization between the two main piston pumps ensures steady straight-line travel and seamless compound movements without drifting.
Detailed Models & Parameters:
Core Series: Nachi PVD-1B Series (Piston + Gear Combo).
