GRUNDFOS91867963
Mechanical seal assembly for Grundfos pumps. Self adjusting elastomer bellows compensate for abnormal shaft end play and primary face sealing wear. This seal's large single coil spring is much sturdier than a multiple spring construction design. The spring is non-clogging, self-cleaning and will not foul up due to fluid contact.
