K3v63dt Hydraulic triplex piston pump for R130 And 150 Excavator Replacement Parts

Product Overview

Key Features

1. Triplex Pump Design

• Dual Main Pumps + Pilot Pump: Combines two variable displacement axial piston pumps (63 cc/rev each) with a fixed displacement gear pump for pilot control, enabling simultaneous operation of multiple hydraulic functions (e.g., boom, arm, bucket) .

• High Efficiency: Achieves 126 cc/rev total displacement and 35 MPa (5,075 psi) maximum pressure, ensuring rapid cycle times for faster digging, lifting, and grading .

2. Variable Displacement Technology

• Load-Sensing & Negative Flow Control: Adjusts oil flow dynamically based on real-time load demands, reducing energy consumption during low-load operations while delivering maximum power during high-load tasks .

• Precision Control: Equipped with a 16-tooth splined drive shaft (SAE J744) and 6-bolt SAE flange mounting for stable, low-vibration operation .

3. Durable Construction

• Wear-Resistant Materials: Features cast iron housing and surface-coated components (e.g., piston shoes, swash plate) to extend service life and withstand harsh operating conditions .

• ISO 9001 Compliance: Manufactured under strict quality control standards, ensuring reliability and consistent performance .

4. Easy Maintenance

• Modular Design: Simplifies disassembly and repair, with rebuild kits available for cost-effective maintenance .

• Filter Compatibility: Works with magnetic suction filters to trap debris and prevent premature wear .

Maintenance & Support

Troubleshooting

• Oil Absorption Issues: Check oil level, suction filter, and seals for air ingress. Replace worn components (e.g., piston shoes, swash plate) to prevent cavitation .

• Overheating: Ensure proper oil viscosity (ISO 46) and clean hydraulic coolers to maintain optimal operating temperatures .

Preventive Maintenance

• Regular Oil Changes: Replace oil every 1,000 hours or sooner if contaminated.

• Filter Monitoring: Clean/replace suction and return filters every 500 hours.

• System Checks: Verify pressure settings and inspect hoses/fittings for leaks.
