Our mechanical seal model 502 can replace AESSEAL B07S and CRANE 502 ,which is widely used for industrial pumps. BO seat and BP seat are usually used for 502 type. The normal material combination include resin carbon\/ceramic\/nbr\/ss304,resin carbon\/tc\/nbr\/ss304,sic\/sic\/nbr\/ss304 ,tc\/tc\/nbr\/ss304 and so on. we also can make changes as customers’requirement or totally design a new type of mechanical seal to meet clients’needs.<\/p>\n
