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 63 (ISO 63 inlet) design has been proven over many years with thousands of pumps installed.
This pump has a pneumatically actuated high vacuum isolation valve and is supplied with: NW10 elbow, NW10 centering-ring, NW10 clamp, water pipe couplings and ferrules, inlet ISO 63 Co-Seal.
