We have a 10m Della Toffola NF series DE filter circa 1994. The shaft seal on the pump has begun to leak. When I dismantled it to have a look I found that the seal is a type that I'm not familiar with. It is a shiny metallic material which is bonded on one side directly the the stainless backplate of the pump housing and the other side is bonded to a stainless ring. The moving surfaces of the seal are on the outside of the pump housing and are lubricated with a water sprayer when the pump is operating. Apparently it would cost over $1000 to replace the parts. My questions are: what is this type of seal called and could anyone recommend a company that could resurface our old parts so we wouldn't have to pay so much just to replace a seal?
BTW - there is no ID plate on the pump
