Manufactured to meet stringent quality standards, this K3V112DTP pump variant is engineered for durability, efficiency, and seamless integration with your Kobelco equipment, ensuring your excavator operates at peak performance.

Key Product Parameters

Pump Type: Swash-plate Type Axial Piston Pump (Variable Displacement)
Model Series: K3V112DTP
Approximate Weight: 110 kg (for K3V112DT variants)
Typical Max. Discharge Flow (per pump in dual pump systems): Up to 220 L/min (for main pumps in Kobelco SK200/SK210 hydraulic systems)
Compatibility: Direct fit for Kobelco SK200-8, SK210 series excavators, and other compatible models.
Application: Main Hydraulic System Pump

Note: Specific "YT6K-17T" sub-variant parameters are typically factory-specific configurations. The general K3V112DTP specifications apply.

Product Advantages & Selling Points

Optimized Performance: Engineered to provide consistent, high-pressure hydraulic fluid, enabling smooth and powerful operation of all excavator functions, from digging to lifting.
Exceptional Durability: Constructed with robust materials and precision engineering, ensuring long operational life even in harsh working environments.
Enhanced Fuel Efficiency: Contributes to the overall fuel economy of Kobelco excavators by minimizing hydraulic pressure resistance and optimizing fluid flow.
Precision Control: Allows for fine-tuned control of excavator movements, crucial for intricate tasks and increasing operator efficiency.
Reliable Integration: Designed as a direct replacement, ensuring perfect fitment and compatibility with existing Kobelco SK200/SK210 hydraulic systems, simplifying installation.

Applicable Equipment & Application Scenarios

This K3V112DTP-YT6K-17T hydraulic pump is specifically engineered for:

Kobelco SK200 Series Excavators (e.g., SK200-8, SK200-10)
Kobelco SK210 Series Excavators (e.g., SK210, SK210LC, SK210LC-8, SK210LC-10)

Application Scenarios & Case Analysis:

In these heavy-duty excavators, the hydraulic pump is the powerhouse, responsible for the vast array of tasks they perform:

Construction & Earthmoving: Essential for digging foundations, trenching, grading, and general site preparation. The pump provides the brute force for the boom, arm, and bucket movements, allowing excavators to move massive amounts of earth efficiently. For instance, in a large-scale commercial building project, the reliability of the K3V112DTP pump in an SK210 ensures continuous digging operations, minimizing downtime and keeping the project on schedule.
Mining & Quarrying: Used for extracting minerals, breaking rock, and loading aggregates. The pump's consistent pressure output is vital for continuous heavy-duty operations in challenging, abrasive environments. A Kobelco SK200 with this pump can be seen tirelessly excavating overburden in a quarry, demonstrating its robust performance under sustained high loads.
Infrastructure Development: Critical for road construction, bridge building, and pipeline installation. Its precise control allows for accurate placement of materials and efficient excavation for utilities. Consider a highway expansion project where an SK200-8 equipped with this pump performs detailed trenching for drainage systems, highlighting its ability to combine power with accuracy.
Demolition: Powers hydraulic hammers and shears for breaking down structures. The pump's ability to maintain high pressure under fluctuating loads is key for effective demolition work.
Material Handling: Facilitates the loading and unloading of various materials like soil, sand, gravel, and waste into trucks or conveyors. The pump ensures quick and smooth cycles for maximum productivity.

The Kawasaki K3V series is a highly regarded line of axial piston pumps known for their reliability and performance in various heavy equipment. Other similar main pumps within the K3V and related K5V series that are often used in similar applications or as alternatives/upgrades include:

Kawasaki K3V112DTH: Another common variant of the K3V112, often interchangeable or used in similar Kobelco models. It offers comparable flow and pressure characteristics, suitable for excavators like SK200-8, SK210-8.
Kawasaki K5V200 & K5V212: These are larger displacement pumps from the K5V series, typically found in bigger excavators (e.g., Kobelco SK330, SK350, SK460) or machinery requiring higher hydraulic power output due to their increased flow capacity.
Other K3V Series Pumps (e.g., K3V63, K3V140, K3V180): Kawasaki produces a range of K3V pumps with varying displacements to match different excavator sizes and hydraulic power requirements. For example:

"K3V63:" Commonly used in smaller to medium-sized excavators (e.g., Kobelco SK120, SK135, SK140).
"K3V140 & K3V180:" Often found in larger medium to heavy excavators (e.g., Kobelco SK250, SK260, SK300), offering higher flow rates for increased power and speed in demanding applications.

Installation & Maintenance: Common Issues & Solutions

Proper installation and regular maintenance are crucial for the longevity and optimal performance of your hydraulic pump. Here are common issues and their solutions:

1. Fluid Contamination

Issue: Dirt, water, or debris entering the hydraulic fluid. This is a leading cause of premature wear, reduced efficiency, and system failure.

Solution: Regularly inspect fluid for discoloration or particles. Follow manufacturer's recommendations for fluid change intervals. Use high-quality filters and replace them promptly. Ensure clean storage and handling of hydraulic fluid.

2. Leakage

Issue: Visible fluid leaks around seals, hoses, or fittings. Leads to fluid loss, reduced pressure, and potential environmental hazards.

Solution: Conduct routine visual inspections for damp spots or puddles. Tighten loose fittings, replace worn or cracked hoses, and renew damaged seals immediately. Consider UV dye leak detection for subtle leaks.

3. Unusual Noise or Vibration

Issue: Whining, knocking, rattling, or excessive vibration from the pump. Often indicates aeration (air in fluid), cavitation (vapor bubbles), worn bearings, or misalignment.

Solution: Check hydraulic fluid level and ensure suction lines are not restricted. Inspect for air leaks in the suction line. Verify pump alignment and mounting. Replace worn bearings and internal components as needed. Maintain proper fluid viscosity.

4. Loss of Pressure / Reduced Performance

Issue: Machine operates slowly, lacks power, or struggles with heavy loads. Can be caused by internal leakage, worn components, or pump inefficiency.

Solution: Inspect for internal and external leaks. Check relief valve settings. Evaluate pump output pressure and flow with diagnostic tools. Worn pistons, barrels, or control components may need replacement.

5. Overheating

Issue: Hydraulic fluid temperature is excessively high. Can degrade fluid quality, damage seals, and lead to pump failure.

Solution: Ensure adequate fluid level and correct fluid type/viscosity. Check cooling system (cooler, fan) for blockages or malfunctions. Verify proper lubrication and minimize excessive friction. Address any issues causing fluid contamination or flow restriction.

Always refer to your excavator's service manual for detailed, model-specific maintenance procedures and troubleshooting guides.
