HyVac HyperVac 3000 Vacuum Pump Model 90904-001

The HyVac HyperVac 3000 is a high-performance direct drive vacuum pump designed for demanding laboratory and industrial applications, such as vacuum distillation, freeze drying, semiconductor processing, and analytical instrumentation. This model, 90904-001, features a two-stage rotary vane design that delivers reliable high vacuum levels with minimal maintenance compared to belt-driven alternatives. Key advantages include quiet operation, robust construction for longevity, and efficient gas ballast for handling condensable vapors. However, it requires regular oil changes and specific HyVac Direct Drive Oil to prevent performance degradation. Equipped with a 1 HP Marathon electric motor, it offers powerful and consistent operation. The unit appears used but in good condition based on visual analysis, with no significant wear, scratches, or damage visible on the housing, fins, or connections. It includes an oil sight glass showing fluid level, power cord, and accompanying bottle of HyVac Direct Drive Oil and documentation (likely installation diagram or manual). Serial number 03358120417 is noted on the faceplate. Compared to similar pumps like those from Welch or Edwards, it provides competitive vacuum depth at a lower cost, though it may consume more power under heavy load. Estimated dimensions and weight are based on visual comparison to standard models; exact data unavailable from manufacturer sources. For resources, refer to HyVac's official site (hyvac.com) for general vacuum pump manuals; specific datasheet for 90904-001 not found, but similar HyperVac series brochure available at hyvac.com/products/direct-drive-pumps.pdf (summarizes features like anti-suckback protection and thermal overload). Model decoder indicates 90904-001 as a 4 CFM direct drive unit with standard KF connections.
