Ideal solution in stuffing boxes with limited space, where Style 550 could not fit.
Style 551 conforms with the EN 12765 L1K lenght requirements, which enables it to be easily installed in all pumps manufactured to this standard.
Will replace most seals without the need of any modification.
It is a balanced seal with a wave spring instead of multiple springs, not in contact with the product, suitable for all appllications, particularly where dense fluids, slurries and abrasive require the use of a heavy duty reliable seal.
