Diffstak 63/150C, 110-125V, 1-ph, 50/60Hz
Quantity
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 (ISO63 inlet) design has been proven over many years with thousands of pumps installed. The unvalved Diffstak's are for systems requiring the highest possible ultimate vacuum or for those which do not need a high vacuum valve.
This pump has an unvalved ISO collar inlet flange and is supplied with: NW10 elbow, NW10 centering-ring, NW10 clamp, water pipe couplings and ferrules, inlet ISO 63 Co-Seal.
* For maximum throughput
