Launch of special variant to range of Scroll Pumps for more aggressive Chemical Applications
Jul 30 2013
Edwards Group Ltd has launched a special variant to its nXDS range of dry scroll vacuum pumps which uses a Chemraz® exhaust valve and stainless steel inlet and outlet fittings, for use in more aggressive applications.
The nXDS-C features the Chemraz® exhaust valve which is used for applications involving pumping organic solvents or other materials that may attack the standard pumps’ fluroelastomer exhaust valve, causing it to deteriorate rapidly. In response to customer demand the nXDS-C variant has been introduced which includes the special exhaust valve pre-fitted as standard. The nXDS will still be readily available, and the previously available upgrade kit will remain as an aftermarket option to give customers the widest choice to suit their individual needs.
The nXDS-C dry scroll pump provides an alternative to oil sealed rotary vane pumps and other dry technologies. It is lubricant free and hermetically sealed so it provides a totally clean and dry vacuum to prevent cross contamination. Unlike other scroll pumps, the bearings are isolated by the bellows, so that any aggressive chemicals involved in the process will not attack them.
It is based on the technology of the well proven nXDS and XDS scroll vacuum pumps, and is ideal for use in wet chemical laboratories, freeze drying, rotary evaporation and distillation.
