$887.4The Graco 15R588 Rod Displacement component represents a critical element in modern pump systems utilized across demanding industrial and commercial sectors. Engineered by Graco, this main material rod displacement part delivers precision control within airless sprayer design frameworks. Fabricated to stringent tolerances, the component ensures dimensional accuracy and reliable cycle consistency under repetitive load conditions. Its robust profile supports extended operational lifetimes. The device has an MPN code of 15R588 and shipping dimensions optimized for compact integration.
At the heart of the Graco 15R588 is a precision-machined rod that delivers consistent volumetric displacement to maintain accurate fluid metering. Its high-strength steel alloy construction resists bending and deformation under cyclical loads, while a polished surface finish reduces friction and wear within the piston bore. With a shipping weight of 10.7 lbs and a shipping length of 20.4 inches, the displacement rod balances strength and manageable mass, offering ease of assembly. Engineers can integrate this rod displacement component seamlessly into existing modules, enhancing both pump efficiency and overall throughput performance.
The Graco 15R588 rod features a proprietary high-grade stainless steel blend formulated to resist corrosion under aggressive coating chemistries. A chemical passivation treatment enhances surface resilience against abrasive additives and solvent exposure. The material selection process prioritizes yield strength and fatigue resistance to support millions of actuation cycles. Combined with advanced machining techniques, the resulting microstructure delivers uniform hardness profiles, minimizing localized stress risers and extending service intervals for even the most demanding professional coatings applications.
Engineers achieve fine control over volumetric displacement through tight tolerances within 0.001 inches on critical diameter surfaces. The rod’s displacement accuracy ensures repeatable stroke volumes, which is essential for high-viscosity fluids and complex multi-stage pumping sequences. Adjustments to rod travel length allow calibration for diverse fluid properties. Performance data indicates deviation of less than 0.5% over extended cycles, contributing to stable output pressure profiles and reduced variance in spray patterns. This level of control underpins consistent deposition rates in precision metering systems.
Extensive bench testing of the 15R588 rod displacement assembly demonstrates sustained pump pressures up to 3000 psi with minimal wear rates. Endurance tests simulate over one million cycles, verifying the rod’s resistance to micro-cracking and fatigue failure. The component’s surface finish and dimensional integrity contribute to improved pump efficiency by reducing friction losses. Test reports also cover thermal expansion behavior under 100°F to 200°F operating ranges, ensuring predictable displacement across temperature fluctuations and safeguarding against performance drift.
The Graco 15R588 rod is backward-compatible with legacy Graco pump modules as well as new-generation fluid delivery systems. Its universal fit design conforms to standard piston bore dimensions, enabling drop-in replacement without modification. Install technicians can quickly verify alignment using reference markings etched into the rod shaft. Compatibility extends across both solvent-based and waterborne formulations, maintaining seal integrity and promoting consistent fluid delivery when paired with high-performance seals and packing sets. Proper installation ensures enhanced seal longevity in demanding pump cycles.
Routine inspection of the displacement rod surface and seal interfaces is crucial to maximizing service life and preventing pump downtime. Graco recommends scheduled disassembly for cleaning and lubrication with compatible grease formulations, reducing abrasive wear. Replacement intervals align with fluid type and operating pressure, generally between 500,000 to one million cycles. Maintenance crews can monitor performance flags through differential pressure readings and adjust service schedules accordingly. Adhering to these protocols helps sustain top-tier output rates and operational consistency.
Under high-pressure loads, the Graco 15R588 rod demonstrates stable dynamic response, with minimal deflection and reliable alignment within the piston bore. Vibration analyses confirm resonance frequencies remain outside operational ranges, preventing fatigue accumulation. The rod’s geometry also facilitates integration with high-pressure filtration systems, preserving fluid purity under extreme conditions. Combined with balanced mass distribution, the rod maintains consistent stroke centerlines, reducing side load stresses on packing glands and enabling smoother pressure ramp-up cycles.
Designed specifically for incorporation into Graco airless sprayer assemblies, the 15R588 rod displacement unit enhances spray atomization consistency. Its precise displacement ensures uniform fluid feed rates, critical when applying viscous architectural coatings and industrial paints. The robust steel core withstands mechanical shocks common in field operations. When coupled with modern spray tips and hoses, the assembly delivers smooth, defect-free finishes in demanding professional coatings environments.
For optimal operation, engineers should pair the 15R588 rod with matched pistons and housings sourced from certified Graco OEM suppliers. Tightening sequences and torque specifications must follow manufacturer guidelines to preserve seal integrity and avoid preload distortions. When pumping abrasive or particulate-laden fluids, incorporating a pre-filter upstream of the pump can prolong rod service life. Regular calibration of flow rates and pressure monitoring helps maintain peak performance and prevents unplanned maintenance intervals.
