Ace BAC-7-75V Mechanical Seal – 5/8" Viton, Carbon & Ceramic

The Ace BAC-7-75V Mechanical Seal is a genuine Ace Pump replacement seal designed for compatible GE-75 and FMC-75 centrifugal pumps. Featuring a 5/8" shaft size and Viton-type elastomer with carbon and ceramic sealing faces, this mechanical seal helps prevent liquid from leaking along the pump shaft during operation.

Mechanical seals are critical components in centrifugal pumps. They create a seal between the rotating shaft and stationary pump housing, allowing the pump to operate while containing the liquid being transferred.

Over time, mechanical seals can wear from normal operation, abrasive materials, chemical exposure, or running a pump dry. A failing seal may result in liquid leaking from behind the pump housing and can eventually damage surrounding components.

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

Whether you're repairing a leaking sprayer pump or performing preventative maintenance, the Ace BAC-7-75V provides an OEM replacement solution for compatible agricultural spraying equipment.
