The Duoseal low rpm vacuum pump is perfect for demanding applications requiring low temperature operation and quiet performance. Its all-metal internal construction and 2-stage rotary valve design provide long-lasting durability, while the 1/3 hp motor delivers up to 0.9 cfm of displacement. With an ultimate pressure of 1 x 10^-4 torr and a 3/4 inch NPT inlet, this vacuum pump is ideal for applications such as medical devices, analytical equipment, laboratories, and automation systems that require precise control over pressures and flow rates. By operating up to 20F cooler than high-rpm direct-drive pumps, the Duoseal low rpm vacuum pump offers a unique advantage in maintaining consistent performance even under demanding conditions.
