Vapor Diffusion Pumps - Diffstak 63, 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. 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.
