Description

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.
