Product details

NACHI PVD‑00B‑14/15/16 Hydraulic Pump

Product Overview

NACHI PVD‑00B‑14/15/16 is a compact dual‑flow Hydraulic piston pump, widely adopted as main power source for 1‑3 ton class mini‑excavators. This hydraulic pump integrates variable piston assembly and auxiliary gear pump, supplying stable pressure and flow for complete hydraulic system. As the core power component of small construction Machine, it drives travel, swing, boom and bucket movements. The performance of this hydraulic pump directly determines operating smoothness and response efficiency of the whole hydraulic system. Available for original equipment matching, aftermarket replacement and on‑site overhaul of engineering Machine。

Working Principle

Engine drives input shaft of the Hydraulic piston pump, pushing piston group inside cylinder block to reciprocate and generate high‑pressure oil flow. The built‑in regulator adjusts swash‑plate angle to change displacement according to load demand. Dual independent output circuits supply oil for travel and working device of Machine separately. The auxiliary gear pump provides pilot oil for control loop of the hydraulic system. When internal components are worn, the hydraulic pump will cause typical faults such as insufficient power, slow action, high internal leakage and abnormal noise. Replacing qualified main pump can restore full working performance of the whole hydraulic system。

Core Advantages

1. Original‑design compact structure, specially optimized for narrow installation space of mini‑excavator and small‑size Machine.

2. Constant‑power load‑sensing control, make full use of engine power, improve operation efficiency of hydraulic system.

3. High‑precision friction pairs, low pulsation and low noise, adapt to frequent forward‑reverse operation of small construction Machine.

4. Integrated auxiliary pilot gear pump, no extra pilot pump required, simplify pipeline layout of hydraulic system.

5. Strict factory pressure testing before delivery. Solve common failures: weak digging force, slow movement, large internal leakage of main hydraulic pump. Good interchangeability for direct replacement during equipment maintenance.

Application Range

NACHI PVD‑00B‑14/15/16 Hydraulic piston pump is the key main hydraulic pump for small‑tonnage excavators. It provides power for complete hydraulic system of mini‑excavator and other compact engineering Machine. Widely used for machinery repair shops, service stations and global spare‑parts trading business .
