Ace BAC-6-150/200-SS Stainless Steel Pump Shaft – 5/8" Keyed

The Ace BAC-6-150/200-SS Stainless Steel Pump Shaft is a genuine Ace Pump replacement component designed for compatible FMC-150, FMC-200, and PTOC-150 centrifugal pump assemblies.

Manufactured from stainless steel, this 5/8" driven shaft transfers rotational power from the pump's drive system to the impeller, allowing the pump to generate flow and pressure.

The shaft features a keyed drive connection and a threaded impeller end, providing the necessary connections for compatible pump assemblies. Its stainless steel construction offers corrosion resistance for agricultural spraying and liquid-handling applications.

Over time, pump shafts can become damaged by bearing failure, corrosion, mechanical seal wear, or improper operation. A worn or damaged shaft may cause vibration, seal leakage, or reduced pump reliability.

Replacing the shaft during a pump rebuild can help restore proper mechanical operation and prevent premature wear of related components.

Whether repairing an existing centrifugal pump or rebuilding a pump for continued service, the Ace BAC-6-150/200-SS provides an OEM replacement solution for professional agricultural spraying equipment.
