Mechanical Rotary Piston Vacuum Pump Popular Sold in European
**DESCRIPTION:**
The Rotary Piston Vacuum Pump is a versatile device that can operate independently or serve as a backing pump when used in conjunction with Roots Vacuum Pumps, Oil Boater Pumps, or Oil Diffusion Pumps. It is essential to equip the pump with appropriate accessories if the gas being pumped is corrosive to ferrous metals, reactive with vacuum pump oil, or contains significant vapor and dust.
**PARAMETERS:**
