مضخة هيدروليكية Nachi PVD-00B-16P-6AG3 271-0907 لـ حفارة صغيرة Caterpillar 301.6C 301.8C

1. Product Core Overview
Manufacturer & Model: Manufactured by Nachi-Fujikoshi, the PVD-00B-16P is a high-performance, variable displacement axial piston pump.

Component Function: It serves as the primary power source for the excavator’s hydraulic system, providing the necessary flow for digging, tracking, and auxiliary functions.

Compact Design: Engineered specifically for mini excavators, balancing a small footprint with high power density to fit within tight engine compartments.

2. OEM Compatibility and Fitment
Direct Fit Part Numbers: This pump is a 100% direct replacement for Caterpillar OEM part numbers 271-0907, 241-7971, 2710907, and 2417971.

Machine Compatibility: Specifically designed for the CAT "C-series" mini excavators:

Caterpillar 301.6C

Caterpillar 301.8C

Plug-and-Play Installation: Features exact mounting flange dimensions and input shaft specifications, ensuring a seamless replacement process without the need for hydraulic line modifications.

3. Technical Performance Features
Tri-Pump Configuration: The PVD-00B series often incorporates a triple-pump design (two piston pumps and one gear pump) within a single housing to provide dedicated flow for different hydraulic circuits simultaneously.

Volumetric Efficiency: Utilizes precision-engineered pistons and cylinder blocks to minimize internal leakage, ensuring maximum breakout force even under high-temperature operations.

Operating Pressure: Designed to handle the standard relief settings of the 301.6C/301.8C series, providing consistent power for travel and attachment operation.

4. Why Partner With a 13-Year Industry Expert?
Technical Mastery: We specialize in Nachi PVD series pumps and understand the critical flow-matching requirements for CAT mini excavators.

Quality Assurance: Every pump undergoes a rigorous hydraulic bench test—verifying flow rates, pressure stability, and seal integrity—before being cleared for international shipment.

Factory-Direct Value: Leverage our 13-year optimized supply chain to access competitive wholesale pricing, avoiding the high markups of local retail dealerships.

Global Logistics: Shipped in reinforced, shock-proof export packaging via DHL, FedEx, or UPS, typically arriving in 3 to 7 business days.

5. Essential Installation Protocol
Case Priming (Mandatory): You must fill the pump housing with clean, fresh hydraulic oil through the topmost case drain port before engine startup. Failure to prime the pump will lead to immediate internal damage due to lack of lubrication.

Contamination Control: If the previous pump failed due to internal breakage, the entire hydraulic system (tank, lines, and oil cooler) must be flushed. Metallic debris can destroy a new pump within minutes.

Filter Update: Always install a new hydraulic return filter and suction strainer during the pump replacement to maintain oil cleanliness.

6. Ordering and Support
