APPROVALS FOR PUMP
November 1st 2003 BOC Edwards has been awarded UL 3101 and CSA C22.2 1010 approvals for its XDS range of dry vacuum scroll pumps.
The approvals have been issued by the Canadian Safety Association as part of the National Registered Testing Laboratory scheme and are the equivalent of the Laboratory Safety standard EN61010 in Europe.
The dry pumping system used in the XDS provides a hermetically sealed pump with no bearings or lubrication products in the vacuum environment, eliminating the risk of contamination and removing the usual vacuum pump oil change requirement. Water vapour is not an issue for the XDS as it can handle large vapour loads without difficulty.
Other features such as the tip seal material and single-sided scroll are said to make servicing simple and fast, reduce wear, improve reliability and extend the pumps working life. More articles from Edwards Ltd: |
