$7.51The Graco 114962 Internal Retaining Ring is a precision-engineered component designed to secure rotary and reciprocating pump assemblies within fluid handling systems. Manufactured to tight tolerances, this retaining ring maintains axial positioning under dynamic loads and protects critical seals against axial displacement. Its robust design integrates seamlessly into various Graco pump modules, ensuring consistent performance in demanding industrial environments. When paired with specialized packings and O-ring assemblies, the 114962 ring enhances system stability and reduces maintenance frequency in high-cycle operations. Ideal for use with an airless sprayer platform, this internal ring contributes to optimized flow paths and reduced pulsation in high-pressure paint delivery setups.
In the context of system integration, the Graco 114962 ring serves as a critical retention element that counters axial thrust and disperses mechanical loads across the pump housing interface. Engineered with precision-ground edges and a contoured profile, the ring delivers uniform contact and minimizes stress concentrations at high cycle rates. Its geometry accommodates differential thermal expansion and secures seal cartridges without inducing radial distortion. This specialized retaining ring is endorsed for use in professional coatings equipment, where consistent retention force is essential to prevent seal migration and ensure uninterrupted fluid metering under pressure.
The internal retaining ring features an internal groove diameter precisely machined to 2.125 inches, with a radial cross-section optimized for uniform load transfer. Finite element analysis guided the contour design to align with pump housing tolerances and to mitigate stress risers under cyclic pressure conditions. Surface roughness specifications are held to Ra 0.8 μm to improve seating accuracy and to minimize micro-crevice formation. Additionally, the groove incorporates a lubricant channel to facilitate assembly lubrication and to support high-pressure seal pack compression in high-pressure filtration modules, where ring stability directly influences filtration element integrity. Design variations include optional chamfered edges and beveled transitions to streamline installation and to reduce interference during ring seating, expanding compatibility across multiple Graco pump series.
Constructed from premium grade 17-4 PH stainless steel or hardened alloy steel, the Graco 114962 ring undergoes controlled heat treatment to achieve a tensile strength exceeding 150 ksi and a Rockwell hardness of HRC 42–45. The corrosion-resistant stainless variant is passivated to resist chemical attack in solvent-based fluid systems, whereas the alloy steel version is phosphate coated to enhance corrosion resistance and to provide a consistent friction profile during installation. This material selection strategy directly impacts pump efficiency and contributes to extended seal longevity by maintaining dimensional stability under fluctuating thermal and pressure cycles.
Laboratory testing confirms that the Graco 114962 ring sustains axial retention forces above 1,200 lbf without permanent deformation and endures over one million reciprocating cycles at 5,000 psi. The ring’s fatigue performance supports continuous operation in heavy-duty industrial environments, including abrasive and viscous media handling. Dimensional inspections post-testing reveal negligible wear development, ensuring repeatable engagement force during maintenance intervals. Its pressure rating aligns with typical airless sprayer and high-volume pump applications, delivering consistent fluid delivery rates and minimizing downtime associated with ring failure or displacement.
Installation best practices recommend the use of precision assembly tools to seat the ring evenly in the housing groove, avoiding localized stress points. Pre-lubrication of the groove and ring surface with compatible grease or fluid ensures smooth deployment and mitigates dry-run wear. Torque specifications for adjacent mating components should be strictly followed to prevent over-compression of the ring and premature distortion. Periodic inspection using borescope or visual gauge validation should be scheduled in accordance with OEM maintenance cycles to verify ring alignment and to detect early signs of groove deformation.
In conclusion, the Graco 114962 Internal Retaining Ring exemplifies advanced manufacturing and design engineering tailored for high-pressure fluid conveyance systems. Its precision geometry, robust material selection, and rigorous performance metrics deliver predictable retention force and long service life in demanding industrial applications. When integrated into Graco pump assemblies, this retaining ring contributes to enhanced pump efficiency, improved seal longevity, and reliable performance with professional coatings and solvent systems. Routine adherence to installation and inspection guidelines ensures maximum operational uptime and safeguards against unplanned maintenance events.
