مضخة هيدروليكية Caterpillar K5V160DP 272-4668 لـ حفارة 330D 336D 336D2 340D 340D2 L

1. Advanced Pump Architecture
Model Designation: The K5V160DP is a dual-variable displacement axial piston pump. It is engineered with two high-pressure rotary groups within a single housing, driven by a tandem configuration.

Volumetric Capacity: Each pump unit provides a displacement of 160 cm³/rev, delivering the massive oil flow required for the heavy-duty boom and bucket operations of 30–40 ton machines.

Model Interchangeability: This pump serves as the high-performance successor to the K3V series, offering higher power density and improved reliability under extreme load.

2. Extensive OEM Part Number Compatibility
This pump is a direct replacement for a wide range of Caterpillar factory part numbers, ensuring perfect fitment for various regional and sub-model configurations:

Standard Series: 272-4668, 310-9486, 247-8992, 295-9674.

High-Pressure / D2 Series: 322-8733, 283-6116, 295-9655, 315-4393.

Latest Revision Numbers: 497-8499, 327-7263, 434-8188, 477-8794.

3. Machine Series Integration
Optimized Fitment: Specifically calibrated for the CAT 330D, 336D, 336D2, 340D, and 340D2 (including L and LRR variants).

Electronic Control Synchronization: The regulators are designed to communicate with the machine's Electronic Control Module (ECM) via the proportional solenoid valves, ensuring the pump does not exceed engine horsepower (preventing engine bogging).

4. Performance & Durability Features
High-Pressure Capability: Rated for a continuous working pressure of 350 bar (35 MPa) with surge protection up to 400 bar.

Enhanced Piston Design: Utilizes hardened spherical heads and specialized brass-plated cylinder surfaces to reduce friction and heat generation during long shifts.

Robust Bearings: Equipped with oversized heavy-duty bearings to handle the high radial loads caused by fluctuating hydraulic demands in quarrying and demolition.

5. 13-Year Expert Service Advantages
Factory-Level Testing: Every unit undergoes a rigorous bench test to verify flow curves, response times, and volumetric efficiency before shipment.

Tiered Quality Options: We provide Original New, Premium OEM, and Certified Remanufactured options to align with your specific maintenance budget.

Global Logistics: Utilizing reinforced, export-grade wooden crates to prevent damage during DHL/FedEx/Ocean transit.

6. Critical Installation Protocol (Pro Tips)
Case Priming: You must fill the pump housing with clean hydraulic oil through the topmost drain port before starting the engine. Running a pump "dry" for even 30 seconds will cause catastrophic bearing failure.

System Flushing: If the previous pump failed due to internal "contamination" (metal shavings), the entire hydraulic tank, lines, and oil cooler must be professionally flushed.

Filter Replacement: Always install new high-pressure and case drain filters. Contaminated oil is the primary cause of premature wear on the precision-lapped swash plate and pistons.
