The Wacker Neuson Motor Frame is a genuine OEM component designed for PST3 750 and PSTF3 750 series submersible pumps. As a direct factory replacement, this part is manufactured to the same specifications as the original, ensuring a proper fit within the pump's motor housing assembly. Wacker Neuson OEM parts are engineered to work together as a system, making this Motor Frame the correct choice when servicing PST3 and PSTF3 series units across multiple voltage configurations.
Key Features
- OEM-Grade Structural Integrity — Manufactured to original tolerances, maintaining the correct alignment and rigidity needed to house and protect the motor internals under continuous submersible operation.
- Drop-In Replacement — Matches the original mounting points and housing dimensions of the PST3 750 and PSTF3 750 motor assemblies, reinstalling exactly as the factory component did.
- Broad PST3 / PSTF3 Coverage — Confirmed fitment across multiple PST3 750 and PSTF3 750 configurations, including 110V and 220V/60Hz variants.
- Protects Motor Longevity — A sound Motor Frame keeps internal motor components correctly positioned and shielded from water intrusion and vibration; a cracked or warped frame can allow moisture ingress and lead to premature motor failure.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number 5000176940 used by authorized service centers worldwide.
The Motor Frame forms the structural shell surrounding the electric motor in Wacker Neuson PST3 and PSTF3 submersible pump units. It holds the motor stator, rotor, and associated components in precise alignment while providing a sealed barrier against the surrounding water environment. When the Motor Frame becomes cracked, corroded, or physically damaged, the motor loses its structural support and moisture protection — leading to misalignment, electrical failure, and ultimately pump shutdown. Replacing a damaged Motor Frame with a genuine OEM part restores the housing to its original condition and safeguards the motor assembly for continued reliable operation.
