Graco 17K690 Pump Repair Kit meticulously restores your equipment’s delivery power, addressing wear points and sealing failures that hinder smooth operation. Professionals relying on consistent pressure and flawless material feed will find this assortment indispensable for reducing downtime. Each component has undergone rigorous quality checks to match original OEM tolerances. Rapid response to kinetic stresses and precise friction control guarantee a return to optimal cycles within minutes. Ideal for heavy-duty applications, it safeguards against leaks and cavitation, helping avoid costly breakdowns and unreliable output when working with versatile coatings, sealants or adhesives.
Maintenance routines become more streamlined after installing this kit on a professional air paint spray gun. Replacement of key components prevents common issues such as uneven spray patterns, surging or pressure loss. Technicians will appreciate the logical grouping of small parts in color-coded trays, which accelerates identification and assembly. Whether performing bench repairs or field service, you can rely on seamless exchanges without sourcing multiple suppliers or improvising with mismatched elements. Quality gaskets and lip seals ensure lasting integrity under high volumetric throughput and elevated temperatures.
Kit includes directional components engineered for high-pressure environments: fluid section seals, back-up rings, packing cups and shaft bearings. A newly formulated elastomer compound resists swelling and deformation in solvent-based systems, while metallic retainer plates maintain structural rigidity. Complementary fasteners, washers and shims facilitate exact positional adjustment of the plunger assembly. Here you will also find a blueprint-style instruction sheet, guiding you through part numbering and torque specifications. Each element is grouped by function to eliminate confusion during service operations. Overall design matches factory specifications guaranteeing interchangeability and peak output. This graco pump repair kit becomes a one-stop solution for pump rejuvenation.
Prepare a clean workbench and gather required tools before beginning. First, depressurize the system and drain residual fluid. Next, detach inlet and outlet manifolds to expose the pumping chamber. Use a calibrated torque wrench to loosen existing fasteners, then extract the worn piston rod and seal assembly. Clean all mating surfaces with lint-free cloths and approved solvent, checking for scoring or corrosion. Slide in fresh packing cups and position new seals against the housing walls. Align the plunger with reference marks and tighten retaining hardware to specified Newton-meters. Finally, cycle fluid at low pressure to verify leak-free operation and full stroke movement.
Optimizing hydraulic flow and mechanical alignment leads to smoother impulse response and precise atomization. Flow rate stabilization prevents pulsation that can disrupt uniform application, ultimately boosting finish quality. With reduced friction losses, energy consumption drops and pump cycles become more predictable under varying load conditions. A precision-ground graco piston rod minimizes lateral play, extending seal longevity and preventing premature failure. Repeatable droplet size control and constant pattern integrity give operators greater confidence when applying coatings or primers in demanding industrial or automotive environments.
Engineered to fit multiple Graco pump families, this kit integrates smoothly with ProXchange, Pro XP and Mark series fluid sections without requiring custom adapters. Threaded connections comply with SAE and metric standards, enabling straightforward installation on different manifolds or retrofit assemblies. Guidance on fluid clearance settings, torque limits and alignment markers ensures correct plunger-to-seat engagement. Compatibility charts provide quick cross-references for model numbers and serial codes, helping technicians validate fitment prior to disassembly. This universality streamlines inventory management and reduces the need for specialized kits in mixed-equipment fleets.
Regular inspections following manufacturer guidelines help identify wear before it escalates into failure. Lubricate moving parts using approved greases to maintain smooth reciprocation and prevent metal-to-metal contact. Compatibility spans Graco’s entire pumping range, including pneumatic, electric and air-driven models. For best results, pair with recommended fluid filters and maintain proper fluid viscosity to reduce cavitation risk. Storing parts in climate-controlled areas safeguards elastomers from premature hardening. This proactive upkeep strategy reduces emergency repairs and extends intervals between major overhauls.
Pursuing excellence in equipment care has never been simpler thanks to dedicated technical service resources. Each purchase of this repair kit includes access to expert guidance, troubleshooting advice and genuine spare parts.
