Vapor Diffusion Pumps - Diffstak 160, Refurbished
The patented, compact water-cooled Diffstak pumps with an integral
cooled baffle offer exceptionally clean pumping with very low
backstreaming, reduced outgassing, and a reduction in the number of
elastomer seals required for installation. The Diffstak design has
been proven over many years with thousands of pumps installed.
The standard Diffstak pumps have integral high vacuum valves and
water-cooled baffles. The valves on this P-model pumps are
pneumatically operated where as the Diffstak M-model pumps have
manually operated valves.
When comparing pumping speeds, note that the speeds quoted for
valved Diffstaks are the speeds above the high vacuum valve, taking
full account of the valve's impedance.
