Two Stage Rotary Vane Vacuum Pumps

These rugged two-stage pumps include all the features needed — long life with minimal maintenance. A built-in anti-suckback valve isolates the pump from the process during power interruptions, and keeps oil out of your system. Gas ballast valves are incorporated for pumping water and other vapors that normally compress to saturation during the pumping process and contaminate the oil. These well ventilated, cool running pumps minimize oil backstreaming and thermal degradation, resulting in a lower cost of operation. The positive oil feed system affords optimal pump lubrication, allowing greater tolerance for oil level changes and the use of a variety of fluids to satisfy diverse applications. The design of the pump is well known, and the pumps can be maintained by pump repair organizations around the world.
