K3V63DT-9N2D 129-7988 118-9868 131-8937 133-6729 for CAT E312B E313B E311B Excavator

Product Introduction

For maintenance teams, this cuts repair time by 35% compared to universal pumps, while the risk of unexpected downtime (a major concern for CAT operators relying on B-series durability) drops by over 50—all thanks to zero mismatched components.​
Durability is a standout strength of the K3V63DT-9N2D, tailored to CAT E312B/E313B/E311B’s work environments. Key internal parts (like pistons and valve plates) are made from high-grade chromium-molybdenum alloy (50% more wear-resistant than standard steel), while the outer casing is reinforced with CAT-approved cast iron to withstand harsh conditions: constant dust exposure from urban construction sites, high-frequency vibration from rock digging, and sudden temperature shifts (from -5°C in winter to 55°C in summer). For operators and fleet managers, choosing this pump boosts the reliability of their CAT B-series machines, extends the equipment’s overall service life by 20% (matching CAT’s typical 6,000-hour maintenance interval), and trims long-term repair expenses by 40% by reducing frequent part swaps.​
Whether used to replace an aging original hydraulic pump (restoring CAT E312B/E313B/E311B’s hydraulic efficiency to 95% of new-machine levels) or stocked as a spare for proactive fleet upkeep (critical for construction firms with tight project deadlines), the K3V63DT-9N2D meets the high dependability and performance standards that CAT B-series owners expect. It has become a go-to solution for ensuring these excavators stay productive and efficient, no matter the job site’s complexity or environmental challenges.​
