Edwards Vacuum Pumps: EO50/60 Diffusion Pump
 
The Model EO50/60 is a compact,
fast warm-up air-cooled diffusion pump supplies complete with
high integrity inlet Co-seal, and flange clamping ring. The jet
assembly is removeable for easy cleaning. It meets the need for a
low-cost, high vacuum pump for use in desk top or mobile
scientific instruments, leak detectors, tube pumping systems and
general laboratory applications.
In many applications the rapid
warm-up capability will enable the EO50/60 to be used without an
isolation valve. However, the pump is not intended for use on
valveless systems where rapid cycling from atmospheric pressure
through the hot pump is required.
Models are available with and
without cooling fans. Models without fans are available as
replacement diffusion pumps for H.P. MSD instruments.
