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 160 (ISO160 inlet) design has been proven over many years with thousands of pumps installed.
This pump is unvalved and has a copper compression gasket flange (ConFlat®).
