Product Overview
The K3V280 Hydraulic Pump, part number 4648368, is a critical component designed to provide the essential hydraulic power needed for the demanding operations of large Hitachi excavators and mining equipment. As a core part of the hydraulic system, this pump is responsible for converting mechanical energy into hydraulic energy, driving the movement of the boom, arm, bucket, swing, and travel functions. A reliable hydraulic pump is paramount for maintaining the efficiency and productivity of your heavy machinery in the toughest environments.
Applicable Hitachi Models and Applications
This K3V280 Hydraulic Pump 4648368 is specifically engineered for a range of large-scale Hitachi Excavators and Mining Equipment, including:
Hitachi EX1900-5 / EX1900-6
Hitachi EX2500-5
Hitachi EX3600
Hitachi EX5500
Hitachi EX8000
These powerful machines are workhorses in the mining industry, large infrastructure projects, and quarrying operations. They are deployed for massive earthmoving, overburden removal, material loading, and high-volume excavation tasks. The reliable performance of the K3V280 pump is vital to ensure these Hitachi Mining Shovels and excavators operate at their peak capacity, handling extreme loads and continuous duty cycles inherent in such demanding applications. Ensuring your EX1900, EX3600, or EX8000 has a properly functioning hydraulic pump is key to minimizing downtime and maximizing productivity in critical projects like mine site development, large-scale civil engineering, and pit operations.

Frequently Asked Questions (FAQs)
Q1: Is this K3V280 Hydraulic Pump a genuine OEM Hitachi part?
A1: This K3V280 Hydraulic Pump 4648368 is a high-quality aftermarket replacement part manufactured to meet or exceed the performance and durability standards of the original equipment manufacturer (OEM) for Hitachi Excavators.
Q2: How do I confirm this K3V280 pump is correct for my Hitachi EX model?
A2: Please verify the part number 4648368 against your machine's service manual or the part number on the existing pump. Confirming your specific Hitachi EX1900-5, EX3600, or EX5500 model and serial number with our team can also ensure compatibility.
Q3: What are common signs that my K3V280 hydraulic pump needs replacement?
A3: Common indicators include slow or sluggish hydraulic functions, loss of power during operation, unusual noises emanating from the pump area (like whining or grinding), overheating hydraulic fluid, or visible leaks from the pump seals. These symptoms on your Hitachi EX series machine could suggest internal wear or failure of the hydraulic pump.
Troubleshooting & Repair Advice
If you suspect issues with your K3V280 Hydraulic Pump on your Hitachi Mining Equipment, here are initial steps:
Symptom: Weak or Slow Hydraulics: Check the hydraulic fluid level and condition. Ensure filters are clean. Inspect hoses and fittings for air leaks which can cause cavitation noise and poor performance. Verify the main relief valve pressure setting.
Symptom: Overheating Hydraulic System: Check the hydraulic cooler for blockage. Confirm the correct type and amount of hydraulic fluid is used. Excessive internal leakage in the pump can also cause overheating.
Symptom: Unusual Pump Noise: Whining often indicates cavitation (air in the system). Grinding or knocking can indicate severe internal wear or contamination.
For complex issues or suspected internal pump failure, it is highly recommended to consult a qualified hydraulic technician or service center. Attempting repairs without the proper tools and knowledge can cause further damage. Replacing the pump with a high-quality unit like the K3V280 Hydraulic Pump 4648368 from a trusted supplier is often the most effective solution for restoring full system performance.
Maintenance Tips for Your Hydraulic System
Regular Fluid Checks: Monitor hydraulic fluid level daily and check its condition (color, odor, presence of particles).
Scheduled Fluid & Filter Changes: Adhere strictly to the manufacturer's recommended intervals for changing hydraulic fluid and filters. Clean fluid is crucial for pump longevity.
Inspect Hoses & Fittings: Regularly check all hydraulic hoses, tubes, and fittings for signs of wear, damage, or leaks. Leaks reduce efficiency and can draw air into the system.
Monitor System Pressure & Temperature: Be aware of normal operating pressures and temperatures for your Hitachi EX series machine. Sudden changes can indicate a problem developing in the hydraulic system, potentially involving the K3V280 pump.
