Overview
The 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 Edwards Diffstak 100 (ISO100 inlet) design has been proven over many years with thousands of pumps installed.
This pump has a manually operated high vacuum isolation valve and is supplied with: NW25 elbow, NW25 centering-ring, NW25 clamp, water pipe couplings and ferrules, inlet ISO 100 Co-Seal.
