OEM Nachi PVD-00B Spare Parts For Small Excavator Hydraulic Pump Repair | Tonkee®

The Nachi PVD-00B series hydraulic pump is known for its reliability and efficiency in small excavator applications.

It operates based on the axial piston pump principle, providing the necessary hydraulic pressure for various excavator functions. The pump comprises several critical components, each with specific functions, and ensuring the availability of high-quality spare parts for these components is vital for effective repairs.

One of the primary components in the Nachi PVD-00B hydraulic pump is the swash plate. The swash plate is responsible for controlling the displacement of the axial pistons, thus regulating the flow of hydraulic fluid. When seeking spare parts for swash plate replacement, it is crucial to consider the material quality and precision machining to ensure proper functioning and longevity. Stainless steel or hardened alloy swash plates are often preferred for their durability and resistance to wear.

Axial pistons are another integral part of the hydraulic pump, converting the rotating motion of the swash plate into linear motion. High-quality spare pistons should be made from durable materials, such as hardened steel, to withstand the repetitive stress and friction in operation. Additionally, proper sizing and precision manufacturing are essential to maintain the efficiency of the pump.

Seals and gaskets play a critical role in preventing hydraulic fluid leakage and maintaining pressure within the pump.

When selecting spare parts for seals and gaskets, it is imperative to choose materials that are compatible with hydraulic fluids and can withstand the operating conditions of the excavator. Nitrile rubber or polyurethane seals are common choices for their resilience and sealing properties.

Bearings are essential for supporting rotating and moving parts within the hydraulic pump. High-quality spare bearings should be selected based on their load-bearing capacity, durability, and resistance to wear. Proper lubrication is also crucial for bearing longevity and smooth operation.

In addition to individual components, it is advisable to consider seal kits and repair kits for comprehensive hydraulic pump maintenance. These kits typically include an assortment of seals, gaskets, and O-rings required for a complete overhaul. Choosing genuine Nachi spare parts or reputable aftermarket parts ensures compatibility and reliability in the repair process.
