| 摘要 | This invention relates to a Dry Running Flexible Impeller Pump and Method of Manufacture that is specifically designed to provide a flexible impeller pump that is capable of being run dry for extended periods of time without damaging the impeller. The pump's housing and end plates are coated with a low friction industrial coating to limit the heat of friction created by the flexible impeller while in use. Additionally the flexible impeller is cast from a pre- molding silicone substrate that contains no mold release and is cast in a mold that is treated with a low friction industrial coating and is cast without mold release. Once the flexible impeller is removed from the mold it is cleaned with alcohol, baked in a vacuum at a temperature of at least 1000C, and then coated with a Paralene N coating by vacuum deposition. | ||||||
