KAWASAKI's K5V series hydraulic pumps are widely used in the main pumping systems of concrete pump trucks due to their high flow rate, high-pressure capability, and structural reliability. The service life of the pump parts directly impacts equipment uptime, repair frequency, and overall efficiency—making it a critical factor for end users.

What Factors Affect Lifespan?

1. Workload intensity – frequent, high-volume pumping under high head pressure increases wear

2. Hydraulic oil cleanliness – contaminated fluid accelerates wear on pistons, cylinder blocks, and valve plates

3. Maintenance frequency – regular oil and filter changes can significantly extend part life

4. Part quality – CNC-machined, heat-treated, high-alloy steel parts offer longer service life

5. Operator behavior – harsh starts/stops, dry runs, or overloading reduce usable life

Average Service Life Under Normal Operation (Example: K5V200):

Note: These are estimates; actual lifespan varies based on usage and maintenance quality.

How to Extend Part Life?

• Use clean, high-quality hydraulic oil

• Avoid prolonged overloading

• Follow recommended service intervals and inspections

• Address early-stage anomalies before further damage occurs

• Replace with high-precision, OEM-matched parts for best performance
