- Consistent Drum Wetting Performance — a properly functioning water tank maintains steady water flow to the drums, preventing asphalt adhesion and protecting mat quality on every pass
- Verified Part Number Integrity — ordering by Bomag part number 88019508 confirms you receive the correct tank geometry and volume for your specific machine
The water tank is the reservoir that supplies water to the drum wetting system on asphalt tandem rollers. During compaction, a continuous film of water is fed onto the drum surface to prevent hot asphalt from sticking and tearing, which protects both the finished mat and the drum itself. When the tank cracks, leaks, or loses structural integrity, water supply becomes inconsistent or stops entirely — leading to asphalt pickup on the drums, surface defects in the mat, and potential damage to drum components. Replacing a failing tank promptly keeps the wetting system operating as designed and protects the quality of the compacted surface.
