It withstands demanding high-pressure filtration cycles and is simple to install, making maintenance fast and straightforward.
When paired with the right pump, the 114699 Thrust Washer enhances output consistency when applying professional coatings by stabilizing fluid flow and minimizing back pressure. This durable accessory is crafted from high-strength materials to resist abrasion and corrosion, extending equipment service intervals and cutting downtime. Ideal for contractors and facility maintenance teams, it supports the delivery of flawless finishes across residential, commercial, and industrial spray tasks. With its precise tolerances and robust construction, it ensures uninterrupted operation even under prolonged high-demand conditions.
$6.3The Graco 114699 Thrust Washer is engineered for rigorous use in high-performance pump assemblies within professional coatings equipment. Designed to manage axial loads and maintain stable shaft positioning, this component plays a critical role in controlling friction surfaces and extending the service life of downstream seals. Its integration into the platen and bearing stack ensures optimal and supports consistent flow rates. Ideal for airless sprayer systems, the washer enhances overall pump efficiency while resisting abrasive wear under high-pressure filtration regimes.
Precision machining to ISO 286 h7 tolerances ensures concentricity within ±0.005 mm, eliminating wobble in rotating elements. The flange thickness of 2.8 mm is selected to absorb transient pressure spikes while retaining flatness over extended duty cycles. Surface treatments contribute to exceptional corrosion and wear resistance, preserving even in aggressive solvent-based coating formulations. Compact and low-profile, the washer demands minimal installation space yet delivers reliable performance at pressures up to 4,000 psi.
The 114699 Thrust Washer is fabricated from a specially alloyed steel optimized for fatigue strength and thermal stability. Through a dual-stage heat treatment involving quenching and plasma nitriding, the part achieves surface hardness up to 1,000 HV and core toughness to 40 HRC. A precision microfinish grinding operation yields a uniform contact surface that distributes axial loads evenly across the bearing face. The washer’s beveled edges are ground at 15° to match the mating thrust collar, reducing edge stress concentration. Specialized phosphating offers supplementary lubricant retention for extended seal longevity under repeated pump cycles.
Laboratory testing under cyclical load profiles shows less than 3% dimensional change after 100 million revolutions at 2,500 psi back pressure. In bench trials with high-viscosity epoxies and urethane coatings, the component maintained frictional coefficients below 0.12, supporting smooth stroke transitions. Test rigs incorporating high-pressure filtration modules confirmed negligible particle embedment on the washer surface. When installed in an airless sprayer configuration, users observed consistent flow stability and improved diaphragm life by 30%. These metrics underscore the washer’s value in demanding coating operations.
Routine inspection of the thrust washer should coincide with pump overhaul intervals every 1,000 operating hours or following abrasive fluid exposure. Visual checks for surface glazing, spalling, or edge chipping can identify early wear. Clean the part with mild solvents, avoiding ultrasonic baths that may induce microcracks. If radial runout exceeds 0.01 mm or frictional drag increases by over 15%, replacement is advised. Maintaining proper torque on the housing clamp and verifying gasket compression angles will further enhance and contribute to system reliability.
Incorporation of the 114699 thrust washer within Graco Ultra Max piston pumps yields immediate gains in cycle stability and volumetric output. When paired with precision-engineered drive couplings, the washer mitigates axial runout that can compromise diaphragm seals and packing sets. Its compatibility with professional coatings—including epoxies, acrylics, and polyurethanes—makes it a versatile choice for both commercial and industrial spray applications. Field technicians report smoother pressure build-up and reduced maintenance downtime when high-pressure filtration units are installed upstream.
Whether servicing contractor-grade spray rigs or factory production lines, the Graco 114699 Thrust Washer provides a robust solution for axial thrust control. Its advanced materials, tight tolerances, and proven performance metrics ensure that pump efficiency remains high and seal longevity is maximized. Ideal for demanding environments where consistent spray quality and minimal downtime are paramount.
