$366.97The Graco 162633 plunger pump displacement unit is a precision-engineered component designed to deliver consistent flow in high-demand industrial applications. Manufactured with hardened stainless steel plungers and ceramic piston sleeves, it ensures minimal wear under corrosive and abrasive conditions. The compact design enables seamless integration within airless sprayer systems for professional coatings, providing a stable pressure profile and reduced pulsation during extended cycles. With a robust housing that withstands high temperature and chemical exposure, the assembly supports reliable fluid transmission and compatibility with both solvent- and water-based media.
The internal architecture of this pump emphasizes redundant sealing and corrosion resistance. Featuring multiple PTFE O-ring stacks around the ceramic piston, it mitigates leakage and extends service life under cyclic loading. The pump’s body is milled from aerospace-grade aluminum alloy, anodized for chemical passivation and surface hardness. Internal galleries are optimized for laminar flow, reducing turbulence and pressure loss. Moreover, the alignment bushings are crafted from wear-resistant bronze, ensuring stable plunger reciprocation. The robust end caps maintain structural integrity at peak pressures, while the exterior finish resists abrasion and chemical etchants. Bore tolerance is maintained at ±0.0002 in for optimal sealing and reduced friction.
Performance testing of the Plunger Pump demonstrates that this unit delivers a steady volumetric output of 0.5 gallons per minute at 2000 psi, with a peak capacity of 0.7 GPM at 3000 psi. The unit’s volumetric efficiency exceeds 92%, reducing wasted energy in idling strokes. Heat generation is managed through embedded cooling fins in the housing, allowing continuous operation without thermal runaway. Vibration dampers at mounting interfaces decrease mechanical resonance, enhancing pump efficiency and reducing noise. Flow coefficients remain stable across diverse fluid viscosities, from low-viscosity solvents to high-viscosity epoxies, with a CV held below 0.5%.
Advanced seal technology is central to this pump’s reliability. The multi-element PTFE U-cup design, coupled with energizing wave springs, maintains consistent contact pressure on the ceramic piston. Dynamic seal assessments under cyclic pressure ramps illustrate minimal volumetric loss after 10,000 cycles, reflecting superior performance of the Displ housing and reduced maintenance intervals. Friction coefficients for the PTFE seals remain below 0.1 µN·s, minimizing actuation torque and enhancing start-up reliability. The assembly supports integrated filtration screens to protect seals from particulate ingress. By combining secondary back-up rings, the design prevents extrusion and seal roll-over, significantly extending downtime intervals and overall service life.
The pump is ideally suited for fluid delivery in coatings lines, injection molding support, and adhesive dosing. Its compatibility with professional coatings such as two-component epoxies and polyurethanes ensures uniform film build and defect-free substrates. When paired with high-pressure filtration modules, it delivers contaminant-free output critical for precision spray applications. Engineers often select this unit for retrofit on robotic spray systems and batch production vessels, leveraging its modular interfaces and standardized mounting bolt pattern for rapid replacement and minimal system reconfiguration. It also handles abrasive slurries with solid content up to 15% by volume when equipped with appropriate filtration upgrades.
Routine diagnostics involve pressure decay tests and volumetric flow verification to detect early wear. Technicians should inspect the ceramic piston for scoring and verify O-ring integrity during scheduled maintenance windows. Flushing protocols recommend a compatible solvent flush to remove residual media, followed by a low-pressure fluid purge before shutdown. Filter elements placed upstream must be swapped regularly to maintain high-pressure filtration performance. The service kit includes pre-lubricated bearings and calibrated wave springs, ensuring rapid field replacement when required. Torque specifications for mounting fasteners and end cap retention bolts are documented in the service manual to prevent uneven seal compression.
Engineers demanding consistent performance and long-term reliability will find this plunger pump displacement unit excels in demanding environments. With its superior materials, advanced seal configuration, and optimized fluid pathways, the pump achieves unmatched seal longevity and pump efficiency. Digital pressure feedback options can be integrated for real-time monitoring and adaptive control. Ideal for airless sprayer platforms and professional coatings distribution, it represents a robust solution for precision fluid handling and high-pressure filtration applications across diverse industrial sectors.
