Edwards Unvalved Diffstak 100/300F Vapour Diffusion Vacuum Pump - NEW

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 (ISO-100 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 is unvalved and has a copper compression gasket flange (ConFlat®).
