Edwards Diffusion Pumps

T

he Model EO50/60 is a compact, fast warm-up air-cooled

diffusion pump supplied complete with high integrity inlet

Co-seal, and flange clamping ring. The jet assembly is

removable 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 Agilent

MSD instruments. The pumps do not come with temperature sensors

but the holes to mount the sensor are available.
