The hydraulic pump is the heart of a concrete pump truck. Operating under high pressure and frequency, its internal parts are subject to wear and fatigue. Replacing components at regular intervals helps prevent sudden failures and costly downtime.
| Component | Suggested Interval (Normal Use) |
|---|---|
| Piston & Shoe Assembly | 2,000 – 3,000 hours |
| Valve Plate (LH & RH) | 3,000 – 4,500 hours |
| Cylinder Block | 3,000 – 4,500 hours |
| Drive Shaft & Bearings | 4,000 – 5,000 hours |
| Springs, Ball Guides | Around 2,000 hours |
Rising oil temperature or noticeable drop in pressure
Oil leakage or cavitation noise from the pump
Detected wear, deformation, or looseness during inspection
Even without failure, preemptive replacement is advised after max service hours
Replace major parts as a set (e.g., piston + cylinder + valve plate) to ensure uniform wear
Replace hydraulic oil and filters after installation
Always choose high-precision, OEM-compatible parts from verified suppliers to ensure performance and longevity
