Ace 21-1.250-V60 Type 21 Mechanical Seal – 1.25" Viton

The Ace 21-1.250-V60 Mechanical Seal is a genuine Ace Pump replacement shaft seal designed for compatible centrifugal pumps, including the Ace GE-860 Series. Featuring a 1.25" shaft size and Viton elastomer, this Type 21 mechanical seal helps prevent liquid from leaking around the rotating pump shaft during operation.

Mechanical seals are essential components in centrifugal pumps. They create a sealing interface between rotating and stationary pump components, allowing the shaft to turn while keeping liquid contained within the pump housing.

Over time, mechanical seals can wear or become damaged from normal operation, abrasive materials, chemical exposure, or running the pump dry. A failing seal may cause liquid to leak from behind the pump housing and can eventually lead to damage to surrounding components.

The 21-1.250-V60 features a Type 21 design with a 1-1/16" working height and Viton elastomer for chemical resistance in compatible agricultural spraying applications.

Replacing a worn or leaking mechanical seal can help restore proper pump operation and extend the service life of an existing centrifugal pump without replacing the complete assembly.

Whether you're repairing a leaking pump or performing preventative maintenance, the Ace 21-1.250-V60 provides an OEM replacement solution to keep your spraying equipment operating reliably.
