$8.81Graco 17W995 KeyWoodruff provides essential mechanical coupling within fluid dispensing equipment, ensuring accurate torque transfer and seating between components. Engineered to fit seamlessly into commercial and industrial pumps, this woodruff key accommodates high-pressure cycles and tight tolerances that characterize modern applications. Its precisely machined curvature conforms to shaft grooves, minimizing installation fuss while maintaining alignment in variable operating environments. Endorsed by technicians seeking dependable performance, it serves as a critical element in sustaining uninterrupted production and efficient maintenance workflows.
Consistency in design underpins the KeyWoodruff’s reliability, as manufacturers employ CNC machinery to maintain tight dimensional tolerances within microns. Heat treatment processes yield a Rockwell hardness between HRC45 and HRC55, balancing toughness and wear resistance. Shot peening adds a layer of compressive stress to eliminate surface microcracks, while phosphate or zinc plating further protects against environmental corrosion. Material selection and finishing are subjected to strict quality control protocols, ensuring each woodruff key performs consistently under high-cycle, high-pressure conditions without premature fatigue.
Installation requires minimal specialized tooling, allowing technicians to position the key in the shaft groove with standard pullers or lightweight presses. Compatible models include multiple Graco pump series, diaphragm pumps, and even select competitor units, reducing spare-part complexity. Recommended clearance guidelines ease seating, and use of a thin film lubricant prevents galling during initial runs. Calibration of torque settings after assembly ensures proper engagement. Its integration with air paint spray gun systems also underscores the key’s versatility across finishing and fluid dispensing applications.
Pump operation relies on precise coordination between rotating elements and reciprocating rods to maintain seal integrity and fluid delivery accuracy. This woodruff key sustains shaft-to-rod alignment, accommodating variations in viscosity and pressure without introducing lateral deflection. When applied with a compatible graco piston rod, sealing lip dance is minimized, preserving O-ring life and reducing the risk of leak paths. Dynamic balancing across the pump assembly benefits from consistent key seating, which in turn helps dampen vibration and noise during high-speed or high-frequency cycles.
Fatigue resistance is critical when parts undergo millions of cycles in demanding environments, and this component excels thanks to controlled grain structure and uniform microhardness. Corrosion testing in salt spray chambers confirms durability even under periodic wash-down or chemical exposure. By resisting wear and minimizing play, the key maintains tight clearances critical for volumetric consistency in fluid metering. Extended-life performance reduces maintenance visits and supports sustainable operation, contributing to lower total cost of ownership for long-term installations.
When wear bands appear or key seating shows deformation, prompt action averts more extensive damage such as shaft scoring or component jamming. Routine inspections should check for metal burrs, uneven surfaces, or groove widening. Service manuals often include diagnostic charts to correlate symptom patterns with wear stages. Replacement is straightforward with kits designed for quick field swaps, but proper removal tools and cleaning procedures must be observed. Keeping spares on hand expedites restoration and helps maintain process continuity under tight production schedules, often using a graco pump repair kit to simplify logistics.
Regular inspection intervals—aligned with pump maintenance schedules—are vital to verify seating integrity and confirm no displacement has occurred. Proper lubrication of shafts prevents fretting corrosion and eases future removal. Documenting key condition as part of service reports helps track wear trends and plan for proactive replacements. OEM replacement woodruff keys ensure compatibility, while detailed drawing references support precise ordering. For complex repairs, consult an authorized service center to access genuine parts, professional assessment, and expert pump repair service.
From automotive coatings to heavy equipment lubrication, this woodruff key supports an expansive range of sectors. Consistent performance under variable load and environmental conditions makes it ideal for manufacturing, construction, and mining operations.
Graco 17W995 KeyWoodruff combines precise engineering, robust materials, and proven application compatibility to deliver reliable performance in demanding fluid handling systems.
