The Graco QuikPak 17H839 Pump Repair Kit represents a paradigm shift in piston pump maintenance for high-performance airless sprayer platforms. Engineered for Ultra Max II and GMAX II Standard Series sprayers, this cartridge-based repack solution leverages modular pre-oiled packings designed to streamline servicing and ensure consistent volumetric displacement throughout intense coating cycles. At the heart of this design, the graco gun repair kit concept introduces a preconfigured assembly of precision-molded elastomeric rings and PTFE backup, optimizing both dynamic and static sealing surfaces. By integrating advanced composite materials with rigorous dimensional tolerances, the system dramatically elevates pump efficiency and minimizes wear, while supporting demanding professional coatings applications in industrial and commercial environments.
Maintenance schedules are simplified through a holistic design that addresses contaminant ingress and wear. By coupling the cartridge system with optimized inlet and outlet geometries, the assembly maintains laminar flow and reduces cavitation risk. The repair process benefits from standardized torque specifications and snap-fit retention grooves that eliminate the need for specialized tooling. Integrated high-pressure filtration upstream of the piston chamber works in concert with the packings to preserve surface finishes and extend reassembly intervals. Technicians can pair this system with calibrated graco paint sprayer filters to achieve superior particulate exclusion, safeguarding internal valve components and sustaining peak pump performance over repeated cycles.
Construction of the QuikPak cartridge emphasizes a balance between resilience and compliance. Elastomeric packings utilize a proprietary blend of hydrogenated nitrile butadiene rubber (HNBR) to resist chain degradation from solvent-based coatings, while PTFE backup rings provide a low-friction sliding interface. Each ring is laser-etched with size and orientation markers to prevent assembly errors. The steel retainer plate incorporates a corrosion-resistant electroless nickel coating, enhancing wear resistance and promoting seal longevity in abrasive or humidity-prone environments. This combination of materials supports operating pressures exceeding 3,000 psi without compromise, ensuring consistent spray patterns and minimal pulsation in demanding professional coatings applications.
Extensive bench testing validates the QuikPak cartridge across multiple parameters, including volumetric efficiency, leakage rate, and cycle life under simulated production loads. Pump efficiency gains of up to 8% have been recorded when replacing worn packings with the 17H839 kit, attributed to tighter tolerances and reduced frictional losses. Seal longevity tests under continuous operation reveal service intervals extending to 1,500 hours, a 50% improvement over legacy packings. Flow calibration at variable temperatures demonstrates stable displacement rates within ±2% of nominal, ensuring consistent output for intricate airless sprayer projects. These metrics underscore the system’s capability to deliver repeatable performance in high-pressure filtration scenarios and accelerate onsite maintenance workflows.
Designed for compatibility with Ultra Max II 1095/1595 and GMAX II 5900 Standard Series airless sprayer frames, the QuikPak 17H839 seamlessly integrates into existing maintenance protocols. Field technicians benefit from an ergonomic cartridge shape that aligns with factory port locations, reducing installation time to under ten minutes. After repacking, the pump immediately recovers optimal spray pressure, eliminating lengthy purge cycles. When combined with premium graco paint sprayer hoses, the system minimizes internal volumetric losses and prevents fluid hammer, ensuring even coating deposition across large panels and architectural structures. This synergy enhances the reliability of professional coatings operations, from large-scale automotive refinish to heavy industrial equipment maintenance.
The QuikPak 17H839 Pump Repair Kit embodies a methodical approach to piston pump revitalization, synthesizing state-of-the-art materials, fluid dynamics insights, and user-centric design. By focusing on precise cartridge alignment, robust seal compositions, and streamlined installation, Graco delivers a solution that advances pump efficiency, extends seal longevity, and bolsters the performance of airless sprayer systems in the most challenging professional coatings environments.
