The Graco 15E887 Convert Clutch Housing is designed as a direct replacement for your Graco pump assembly, offering precision alignment and robust construction for demanding applications. Built to meet stringent industry standards, it ensures optimal clutch action even in harsh environments. It seamlessly integrates into your airless sprayer system, delivering smooth operation and reliable clutch engagement under continuous use. The precision fit guarantees leak-free performance and easy assembly. With enhanced sealing and corrosion-resistant materials, this component supports consistent performance while minimizing maintenance, even when paired with advanced high-pressure filtration units.
Ideal for contractors and industrial users applying professional coatings, this clutch housing enhances workflow efficiency and reduces downtime. Its improved torque transfer and resistance to wear ensure uniform spray patterns, making it an essential upgrade for those seeking dependable results in high-volume painting operations.
The Graco 15E887 Convert Clutch Housing is a critical component designed for rugged industrial use, integrating directly into high-performance airless pump assemblies. Machined from aerospace-grade 6061-T6 aluminum, this housing exhibits exceptional dimensional stability and corrosion resistance under cyclic loading. It features precision bore tolerances within ±0.002 mm and surface finishes down to Ra 0.4 µm, ensuring optimal shaft alignment and bearing retention. Internally, the clutch conversion mechanism maintains engagement torque control up to 45 Nm, allowing smooth ramp-up of rotational speed and mitigating shock loads on drive components. Its port configuration accommodates standard seal cartridges and pressure-G media passages with streamlined flow profiles to reduce turbulence.
The housing is optimized for integration with state-of-the-art airless sprayer pump systems, delivering consistent fluid displacement across a wide range of viscosities. Engineers report up to a 15 % improvement in volumetric efficiency due to the housing’s internal chamber geometry, which minimizes dead volume and backflow. In professional coatings applications, this translates into uniform atomization and reduced pulsation at the spray tip. High-pressure filtration cartridges can be mounted directly to the outer mounting flanges, providing a compact solution for filtering particulate contaminants before they reach the clutch mechanism. Moreover, the housing’s rigid construction reduces structural vibration and supports reliable torque transfer even during heavy-duty cyclic operation.
Designed for demanding industrial workflows, the Graco 15E887 housing includes machined grooves for O-ring seal retention, ensuring superior seal longevity and leak-free performance in fluid-handling circuits. The sealing surfaces are engineered to comply with ISO 3923 standards for dynamic elastomeric seals. When combined with nitrile or fluorocarbon seal materials, the housing resists chemical attack from solvent-based coatings and cleaning agents. Its anodized surface treatment further enhances abrasion resistance and mitigates fretting corrosion at mating interfaces. Maintenance intervals can exceed 2,000 operational hours when properly lubricated with synthetic pump gear lube, preserving the precision fit between the clutch plates and shaft hub.
The aluminum alloy body features strategically placed stiffening ribs to withstand internal pressures up to 1,200 psi without elastic deformation. Finite element analysis (FEA) confirms a safety factor of 2.5 for yield strength under maximum operating loads. Critical junctions between the gearbox interface and fluid passages are reinforced with cross-drilled tie rods, enhancing torsional rigidity while maintaining a compact envelope. Threaded ports follow UNF standards and are chamfered to optimize hose and fitting assembly. The housing’s modularity allows for quick reconfiguration from single-stage to two-stage clutch setups, supporting both low- and high-viscosity fluid applications.
Performance testing demonstrates that the 15E887 housing contributes to improved pump efficiency through reduced mechanical losses and enhanced thermal management. The integrated heat-dissipating fins channel heat away from the clutch engagement surfaces, maintaining consistent friction coefficients even under continuous duty cycles. Temperature differentials between the fluid inlet and outlet remain within 10 °C under typical conditions, preventing viscosity shifts that could disrupt flow rates. As part of an air-driven pump assembly, the housing’s optimized internal flow passages deliver smooth transition through high-pressure filtration elements, minimizing pressure drop while ensuring reliable particulate capture.
For assembly, align the clutch housing with the pump drive flange and secure using Grade 8 bolts torqued to 30 Nm. Apply a thin layer of high-temperature thread locker to prevent bolt loosening under vibration. Slide the clutch plates into the housing cavity, ensuring proper orientation of friction and drive discs. Verify shaft engagement by rotating the assembly manually before applying drive torque. When integrating filtration modules, follow recommended filter micron ratings (10 µm or finer) to protect the clutch surfaces from abrasive wear. Routine inspections every 500 operational hours should include seal integrity checks and lubrication of the internal bearings.
In professional coatings environments, this housing supports rapid changeover between different fluid formulations. The modular design allows cleaning and component swap-out without removing the entire pump assembly, reducing downtime and maintenance costs. Its compatibility with a variety of pump geometries makes it a versatile solution for automotive refinish, industrial coating, and specialty material dispensing. By combining robust construction, precise machining, and smart fluid-path design, the Graco 15E887 Convert Clutch Housing stands as a benchmark for engineering reliability in high-pressure fluid delivery applications supporting professional coatings industries worldwide.
