$210.91Engineered for demanding industrial applications, Graco 187705 Housing Pump brings together exceptional durability and precise fluid control in a compact package. Its robust housing structure excels under high-pressure scenarios, offering a reliable conduit for viscous materials such as coatings, adhesives, and sealants. Leveraging advanced manufacturing processes, each unit delivers repeatable performance while minimizing downtime associated with wear and tear. Professionals appreciate its resistance to abrasion and corrosion, enhancing service life and cutting replacement intervals. Versatile mounting options and standardized connection ports make integration into existing fluid delivery systems straightforward, setting a new standard for operational efficiency.
Aluminum alloys with panoramic machining deliver a weight-to-strength ratio ideal for continuous operation without compromising structural integrity. Tight tolerances in the internal fluid channels support consistent pressure transference, cutting pulsation and ensuring uniform spray patterns in downstream equipment. Integrated seals crafted from high-performance elastomers maintain leak-free operation at extreme temperatures. Designers have paid special attention to the housing’s geometry, reducing turbulence and minimizing dead zones where material buildup can occur. This meticulous engineering approach not only extends component longevity but also streamlines routine inspection tasks and part interchangeability.
Operators witness impressive flow stability when using this housing pump alongside popular systems. It excels at handling a wide range of viscosities, from light solvents to heavy latex formulations, without sacrificing consistency. Maintenance crews report swift priming cycles and reduced purge times, leading to faster job turnover on-site. Compatibility with proprietary tips and nozzles further enhances its versatility across finishing, foaming, and sealing tasks. For teams upgrading existing setups, seamless coupling with a magnum airless paint sprayer amplifies productivity by delivering uninterrupted fluid supply under challenging conditions.
Disassembly follows a logical sequence aided by hash-mark indicators and quick-release fasteners, allowing technicians to swap wear parts in minutes. Corrosion-resistant coatings on both internal and external surfaces simplify cleaning protocols, reducing solvent consumption and environmental impact. Users can source genuine replacement diaphragms, valves, and manifold sections without resorting to aftermarket substitutes. Periodic inspections using standard gauges ensure that clearances remain within factory specifications, promoting leak-free operation. OEM advocates praise the streamlined availability of graco quickshot parts for midstream repairs and bench-level rebuilds, maintaining uninterrupted workflow.
Pump dimensions measure 4.8 inches in diameter with a length of 7.2 inches, fitting standard mounting plates. Inlet and outlet ports utilize 3/8-inch NPT threads for secure hose attachment, and port alignments are optimized to reduce pressure drop. Maximum operating pressure reaches 3000 psi, while temperature tolerance spans -40°C to 80°C without seal degradation. Weight at 2.1 pounds ensures stability under high-cycle conditions. Installation requires only metric hex wrenches and a calibrated torque driver set to 25 Nm for housing bolts, granting repeatable assembly and eliminating common misalignment issues.
While many pumps target a narrow set of uses, this housing assembly integrates seamlessly with sprayers, proportioners, and mixing dispensers alike. Automotive refinish shops benefit from reduced color changeover times and cleaner cycles, cutting waste in high-turnover environments. In construction, joint sealant operations leverage its consistent output to lay bead profiles with exacting thicknesses. Even specialty markets, such as aerospace and marine coatings, appreciate stringent contamination control afforded by smooth cavity surfaces and minimal dead zones. Adapters available for robotic applicators further expand its utility, enabling programmable deposition in automated welding or sealing lines. Real-world tests confirm stable performance over multi-shift operations, reinforcing its suitability for teams demanding both precision and durability in dynamic workstreams.
Integration of Graco 187705 Housing Pump within industrial fluid systems reflects a commitment to robust performance and maintainability. Precision engineering and material selection combine to ensure this housing remains a cornerstone in high-demand environments. For service providers and production managers, investing in this component yields measurable gains in uptime and finish quality. Certified technicians can perform an overhaul or install a graco replacement pump with minimal lead time, supported by comprehensive documentation and expert training programs.
