425763 Mechanical Seal for Grundfos Pumps, 16mm Shaft

• IN STOCK •

Replacement mechanical pump shaft seal for Grundfos pumps. A bellows type seal with a separate rotary unit and stationary seat. This type of seal allows torque transmission across the spring and around the bellows. Therefore it is not designed for hard material pairings in applications with poor lubrication. Due to the bellows, the seal does not wear the shaft and axial movement is not prevented by deposits or seizure on the shaft.

Made in the United States by U.S. Seal Manufacturing.

U.S. Seal is the industry standard for quality aftermarket pump seals. For over 60 years, they have been manufacturing seals that are more reliable than OEM pump seals at a fraction of the cost.
