Graphite Metallizing Corporation is pleased to announce that GRAPHALLOY® Grade GM 695.3 Bearings have been granted Water Regulations Advisory Scheme (WRAS) approval. This follows the recent certification of NSF/ANSI grades as Graphite Metallizing continues to expand the GRAPHALLOY product line to meet drinking water regulations worldwide.
Through a stringent testing process, WRAS approval indicates that the GRAPHALLOY bearings comply with the high standards set out by the water regulations within the United Kingdom.
In addition, WRAS approval specifies that GRAPHALLOY GM 695.3 Bearings are “suitable for contact with wholesome water for domestic purposes” because it has met the requirements of BS 6920-1:2000 (“Suitability of non-metallic products for use in contact with water intended for human consumption with regard to their effect on the quality of water”).
Bushings made of WRAS approved GRAPHALLOY are used in municipal water system pumps. These bushings have been found to operate for more than 10 years in these services and to provide solutions that eliminate requirements for lubrication systems, including pre-lubrication.
