Inquiry (采购产品): Graphie Vanes I am looking for a supplier of graphic vane material as replacement parts in rotary vacuum pump. Most pumps are oil lubricated but graphic vanes are used in pumps where oil vapor is unacceptable. The vanes wear down over time and need replacing. The graphite is self lubricating and also forms the seal in the cylinder. I have a sample of the original material and a dummy of the original size, which is what we need. Material needs to be hard enough to withstand wear and also able to handle heat build up from friction. **** Hidden Message ***** Richard Thomas 66220 Company: Envelope Equipment Sales E-mail: envelop_equipment@yahoo.com **** Hidden Message ***** envelop_equipment@yahoo.com
