The PT125 comes standard with a 100 gal (379 l) pressurized water system utilizing an electric diaphragm pump. Each tire has one spray nozzle with a 100 mesh filter in addition to the primary 80 mesh filter and tank inlet strainer.
The Volvo PT125 is a nine-wheel pneumatic tire compactor typically utilized on hot mix asphalt and on chip-seal applications. The four front tires are staggered in position to provide overlap with the five rear tires, resulting in complete material coverage for consistent texture and appearance. Uniform compaction, even on irregular surfaces, is achieved using tire oscillation to maintain uniform tire contact pressure.
