Product Description

Nachi PVD Series Hydraulic Main Pumps for Mini Excavators

Product Overview: The Nachi PVD Series represents the high-efficiency power core of mini excavator hydraulic systems. Featuring a highly compact, integrated design, this series combines two variable displacement piston pumps and one or two fixed gear pumps (Triple or Quadruple pump configurations) within a single housing. Featured models such as the PVD-1B-29BP-12G5-4614G and PVD-15B-32BP-9AG5-4634J are specifically engineered for 1.5-ton to 3.5-ton excavators, providing 100% compatibility with leading brands like Kubota, Komatsu, Yanmar, and Kobelco.

Key Technical Advantages:

  • Multi-Pump Integration: Delivers independent power to multiple circuits via a single-shaft drive. Piston pumps power travel and digging, while gear pumps manage blade, swing, or pilot controls.

  • Superior Constant Power Control: Equipped with a precision power-regulating mechanism that modulates flow based on engine load, preventing stalls and maximizing operational efficiency.

  • High Reliability & Durability: Built for the harsh environments of construction machinery, with reinforced rotating groups that ensure an extended service life under frequent shock loads.

  • Compact & Lightweight Footprint: Minimal installation space requirements significantly reduce overall machine weight, allowing for optimized machine layouts.

  • Precise Synchronicity: Excellent flow synchronization between the two main piston pumps ensures smooth straight-line travel and seamless compound movements.

Detailed Models & Parameters:

  • Core Series: Nachi PVD Series (Piston + Gear Combo).

  • Model Keywords: PVD-0B-24P-8G3-4837B, PVD-1B-29BP-12G5-4614G, PVD-15B-32BP-9AG5-4634J.

  • Displacement Range: 24cc, 29cc, 32cc (Main Pumps).

  • Pressure Ratings: Piston section rated at 21-25 MPa; Peak capability up to 28 MPa.

  • Target Applications: Mini excavators (1.5t – 3.5t), compact drilling rigs, and landscaping machinery.
