Product Description
K3V63DT-9N2D Hydraulic Pump for CAT E312B E313B E311B Excavators
Product Overview
This precision-engineered hydraulic pump replacement delivers superior performance and reliability for CAT B-series excavators. Engineered to reduce repair time by 35% compared to universal pumps, it significantly decreases the risk of unexpected downtime by over 50% through perfectly matched components.
Enhanced Durability Features
The K3V63DT-9N2D is specifically designed for the demanding environments of CAT E312B/E313B/E311B excavators. Key internal components including pistons and valve plates are manufactured from high-grade chromium-molybdenum alloy, providing 50% greater wear resistance than standard steel. The reinforced outer casing utilizes CAT-approved cast iron to withstand harsh operating conditions including constant dust exposure, high-frequency vibration from rock digging, and extreme temperature variations from -5°C to 55°C.
Performance Benefits
  • Extends equipment service life by 20%, matching CAT's standard 6,000-hour maintenance intervals
  • Reduces long-term repair expenses by 40% through decreased part replacement frequency
  • Restores hydraulic efficiency to 95% of new-machine performance levels
  • Ideal for both replacement of aging original pumps and proactive fleet maintenance
