Arbe Vacuum Pump - 3 CFM

Arbe Two-Stage Vacuum Pump – 3 CFM, 1/2 HP for Jewelry Casting

The Arbe Vacuum Pump is engineered to deliver exceptional performance for professional jewelry casting applications. Designed for reliability and deep vacuum draw, this two-stage, direct-drive vacuum pump features a powerful 1/2 HP motor and 3 CFM free air displacement, making it ideal for vacuuming RTV molds, urethanes, investment, invested flasks, and vacuum-casting small solid flasks.

Vacuuming is a critical step in the jewelry casting process—all RTV molds must be vacuumed to remove trapped air bubbles that can cause surface defects and casting failures. The Arbe Vacuum Pump provides a strong, consistent vacuum to ensure clean molds, dense investments, and high-quality cast results.

Powerful Two-Stage Performance

This pump delivers a deep vacuum draw of 29-1/2 inches of mercury (75 cm) at sea level, allowing air to be efficiently removed from molds and investments. The two-stage design ensures faster evacuation and higher ultimate vacuum levels than single-stage pumps, making it suitable for both mold preparation and small-scale vacuum casting.
