AX-65 Diffusion Pump
The AX-65 diffusion pump is a high-performance, air-cooled pump designed with bench-top analytical instruments in mind. Its vertical finned boiler and high power provide stable pumping and high helium pumping speed. This pump can be ordered with a cold cap or a dense baffle. The pump includes a fluid-level sight glass that indicates the fluid level at all times.
Product details
Features
- High performance specifications means higher, cleaner vacuum levels
- Fluid-level sight glass provides quick indication of pump fluid status at all times
- The wide range of available pump configuration and flange combinations optimizes pump performance and fit for your application
- Compact design makes integration into space-limited equipment easy
- Full thermal protection guards against all over-temperature conditions
- “Pump-ready” thermal switch sends a signal when pump is operational
- Finned, vertical boiler promotes stable pumping, especially of light gases
- Three-stage fractionating jet with ejector stage purifies pumping fluid, giving higher forepressure tolerance
