$8.57The Graco 15F947 Magnetic Shield is an engineered sealing component developed to reinforce the integrity of high-pressure fluid circuits. Crafted for use in demanding industrial environments, this magnetic barrier interfaces with pump housings and valve assemblies to reduce particulate ingress and fluid cross-contamination. Its compact form factor integrates seamlessly into airless sprayer systems, while its advanced magnetostatics offer reliable performance under extreme pressures and temperatures encountered during professional coatings application.
By establishing a passive, non-contact barrier, the 15F947 Magnetic Shield optimizes fluid filtering and enhances high-pressure filtration efficiency. Its integration reduces wear on dynamic seals, prolongs seal longevity, and contributes to overall pump efficiency improvements. Designed for retrofit in existing Graco pumps and compatible aftermarket modules, the shield delivers a straightforward upgrade path without altering core fluid pathways.
The internal architecture of the Graco 15F947 consists of a two-piece stainless steel housing welded to secure the neodymium magnet core. Tolerances are held to ±0.001" on the magnet-to-sleeve interface, ensuring concentric alignment and uniform radial clearance. A nitrile backup O-ring is captured within a precision groove, providing redundant sealing against the pressurized fluid. Finite element analysis informed the thickness distribution, balancing magnetic flux density against mechanical yield limits under 5,000 psi operation.
Extensive bench testing demonstrates that the magnetic shield maintains full sealing performance up to 5,000 psi and temperatures approaching 200°F. When paired with fine-mesh filter elements, it prevents sub-micron particulates from breaching the primary seal, reducing maintenance intervals by up to 30%. The design enhances pump efficiency by reducing internal leakage and pressure drop, delivering consistent flow rates critical for spray pattern uniformity in professional coatings environments.
Routine inspection involves verifying magnetic flux strength and O-ring integrity. The nonabrasive magnetic seal eliminates frictional wear, extending replacement cycles. With no grease or lubricant required, the shield remains maintenance-free in operation, minimizing downtime. In field trials, service life exceeded 1,000 operating hours under continuous high-cycle conditions, showcasing the shield’s robustness and contributing to lower lifecycle costs.
Constructed from 17-4 PH stainless steel, the outer sleeve benefits from electroless nickel plating that enhances hardness and delivers exceptional corrosion resistance in solvent-rich coatings environments. The neodymium magnet core is encapsulated to prevent direct fluid contact, preserving magnetic performance over time. Elastomer components can be specified in Viton or EPDM for chemical compatibility across a range of solvents and water-based fluids, ensuring reliable operation in diverse industrial settings.
For specialized applications, alternative magnet grades and diameter sizes are available to tailor the shield’s holding force and sealing clearance. Flange and threaded adapter options enable direct integration into existing manifolds or bespoke pump blocks. The simple push-fit installation requires no special tooling, allowing technicians to field-upgrade units in minutes. Custom engraving can be added for part traceability and inventory management in large-scale production lines.
When installed upstream of final pump stages, the 15F947 Magnetic Shield serves as a first-line defense against abrasive particulates generated during coating circulation. Its passive nature ensures failsafe operation even under power loss or sudden pressure spikes. By pairing the shield with high-efficiency filters and optimized pump circuits, engineers can achieve superior surface finish quality, reduce recoat times, and maintain consistent spray performance over long operating shifts.
