The Comet SW5540S is a high-capacity, hot-water-capable solid-shaft triplex pump designed for demanding cleaning systems that require serious power and reliability. With a rated flow of 5.5 GPM at 4,000 PSI, it’s engineered to deliver superior performance for commercial and industrial applications where consistent pressure and high throughput are essential.
Featuring a 24 mm solid shaft suitable for belt drives, gearboxes, or flex couplers, the SW5540S is built to last. Its robust build includes a die-cast aluminum crankcase, forged brass head, solid ceramic plungers, and generous oil capacity (37 fl oz) to manage heat and maintain smooth operation under heavy loads.
Whether you’re retrofitting existing equipment or building a new rig, this pump offers both power and longevity in a compact footprint.
