DESCRIPTION: The Rotary Piston Vacuum Pump is a versatile device that can operate independently or serve as a backing pump when combined with other vacuum pumps such as Roots, Oil Boater, and Oil Diffusion Pumps. It is essential to use appropriate accessories if the exhaust gas is corrosive to ferrous metals, reactive with vacuum pump oil, or contains significant vapor and dust. PARAMETERS:
