Mechanical Seal for Booster Pumps

This Viton mechanical seal fits Flint & Walling booster pumps and matches Grainger part numbers 22W727 through 22W737. It is a direct replacement component for maintaining pump sealing performance in industrial plumbing systems. The seal is supplied new and ready for installation.

Viton Material and 5/8 Inch Diameter

The seal uses Viton elastomer for chemical resistance and high-temperature durability in demanding fluid-handling applications. Its 5/8 inch diameter matches the shaft size on compatible Flint & Walling pump models. The construction supports reliable sealing under continuous booster-pump operation.

Replaces Worn Seals in Listed Pump Series

This part replaces failed seals in Flint & Walling booster pumps referenced by Grainger numbers 2PC42 to 2PC48, 4YC09 to 4YC12, and PB series models including PB0512S051, PB0712S071, PB0712S073, PB1014S101, PB1014S103, PB1016S151, PB1016S153, PB2711S201, PB2711S203, PB2714S301, and PB2714S303. The upgrade is worth it when leakage appears or during scheduled rebuilds. Buyers needing a different shaft diameter or elastomer should verify specifications before ordering.

What shaft diameter does the 5/8 in seal require?

Which way does the Viton seal face during assembly?

Install the carbon face toward the impeller and the stationary seat toward the motor; reversing them causes immediate leakage.
