The Graco 17W996 lower pulley delivers reliable performance for maintenance on professional spray systems. Engineered from precision-machined steel, this replacement component ensures smooth operation under demanding conditions. Whether you’re servicing an airless sprayer to optimize paint flow or maintaining system efficiency, the robust design accommodates rigorous daily use and helps prevent costly downtime. With precise measurements of 3.95 inches in length and a height of 2.3 inches, it fits seamlessly into most Graco pump assemblies. The pulley’s 3.85-inch width provides balanced load distribution, enhancing durability during continuous operation.
Designed for compatibility with high-pressure filtration circuits, this pulley supports precise tension control to maintain consistent coating quality. Ideal for use with professional coatings, it offers exceptional wear resistance and corrosion protection to extend component lifespan. Easy to install and compatible with a range of spray pump configurations, the Graco 17W996 lower pulley is an essential upgrade for technicians demanding lasting reliability.
Industrial operators rely on precision-engineered components to maintain fluid-handling equipment at peak efficiency, and this lower pulley is no exception. Manufactured with high-grade aluminum alloy, it offers exceptional resistance to corrosion and mechanical wear. Careful attention to dimensional tolerances ensures smooth rotation under variable loads, making it a go-to choice for repair and maintenance professionals seeking reliable, long-lasting performance.
Precise machining of each groove maintains optimal belt tracking, preventing slippage and uneven wear during extended duty cycles. A sealed inner race keeps contaminants at bay, increasing service intervals and lowering downtime. Technicians appreciate how this pulley integrates seamlessly into existing pump assemblies, avoiding the need for costly adapters or modifications.
Featuring a 6061-T6 aluminum body, the pulley balances rigidity with weight savings. Finite element analysis guided the wall thickness distribution, ensuring structural integrity under radial loads up to 200 pounds. Anodized surface treatment not only improves corrosion resistance but also offers a uniform finish that stands up to chemical exposure common in industrial spray applications.
Installation requires only standard hand tools and basic mechanical skills. Alignment marks etched into the hub simplify belt tensioning, while a chamfered bore ensures a snug fit on shafts up to 0.750 inches in diameter. Periodic inspections of the bearing assembly and lubrication port will extend service life, especially in environments where particulate ingress is a concern.
Integration with other accessories is effortless, whether you’re extending hose reach or adding spray protection. Users often pair it with a graco spray hose upgrade to streamline fluid delivery. In conjunction with proper hose routing, this pulley supports stable flow rates and reduced pulsation for consistent application results.
Rotation efficiency remains high thanks to sealed roller bearings designed for high-speed operation. Keeping spray tips clear is critical in precision coating tasks, so incorporating a graco tip guard can further protect components from overspray and impact damage. This combined approach extends the life of critical parts throughout the system.
When operating in dusty or moist environments, filtration becomes paramount. Integrators often specify graco filters and strainers upstream of the pump to prevent clogging and preserve component longevity. By capturing debris before it reaches the pulley assembly, maintenance intervals lengthen and machine uptime improves.
Compatibility testing confirms that this pulley works flawlessly with both single- and dual-pump configurations. Users report smooth acceleration and consistent torque transfer even under fluctuating pressure demands. Its rugged construction stands up to the rigors of daily operation in paint booths, concrete sealing rigs, and industrial cleaning systems.
Proper alignment and belt tension are critical to avoid uneven wear. Service technicians should follow torque specifications when mounting the pulley, and always verify that the shaft key seats fully into the keyway. A small application of anti-seize compound on mounting surfaces can prevent galling without affecting runout tolerances.
End users benefit from a comprehensive warranty program that covers manufacturing defects and unexpected failures. Training classes available through authorized service centers ensure your team can perform installation and routine maintenance with confidence. For replacement parts or technical support, consult authorized distributors who stock genuine components and offer expert troubleshooting guidance.
Graco 17W996 Pulley, Lower stands out as a high-precision, durable solution for demanding fluid-handling installations.
