About this model
The Centurion P8 Belt Drive Triplex Pump (85.120.106B) represents the pinnacle of professional pressure washer engineering. Manufactured by CP, a global leader in high-pressure pump technology, this model is built to perform in the most demanding cleaning environments. Designed for gas or electric-powered systems, it delivers a commanding 4,000 PSI of pressure at 4.0 GPM, making it ideal for contractors, industrial maintenance professionals, and equipment manufacturers who demand exceptional performance and reliability.
With a belt-driven system running at 1,450 RPM, the P8 operates cooler, quieter, and longer than conventional direct-drive units. Its nickel-plated brass manifold, ceramic plungers, and external unloader provide the foundation for smooth operation, corrosion resistance, and extended service life. Whether you're cleaning commercial fleets, construction equipment, or large-scale industrial surfaces, the Centurion P8 is engineered to handle it with precision and strength.
The Centurion P8 (CTB1S) isn’t just powerful — it’s purpose-built. Its 4,000 PSI pressure output delivers enough cleaning force to strip paint, cut through grease, and remove hardened grime from the toughest surfaces. The 4.0 GPM flow rate provides excellent coverage and rinsing capability, striking a perfect balance between cleaning efficiency and controlled precision.
