Description
These premier Welch-manufacturered pumps are high capacity, high-vacuum, and are built for chemical-duty. These PTFE dry vacuum pumps provide either 1.5 torr ultimate pressure (with a 65L/minute flow) or 6 torr ultimate pressure (with a 100L/minute flow).
Both pumps rate for vacuum ovens and laboratory applications. With PTFE (polytetrafluoroethylene) heads, perfluoroelastomer valves, and PTFE-coated molded diaphragms, these pumps are highly resistant to harsh chemical vapors. The intake threads are NW 16 - 1/4" NPT.
Pumps evacuate an enclosed area and move fluid or gas from one location to another. Pump choices are guided by the specific application and required substance compatibility.
