Oberdorfer 4Ad45T Close Coupled Adaptor Kit — Genuine OEM Motor Mounting Solution
When you need to connect an Oberdorfer pump head to a standard NEMA-frame motor with precision and confidence, the 4Ad45T Close Coupled Adaptor Kit is exactly what the job calls for. Engineered by Oberdorfer — a brand with over a century of pump manufacturing experience — this kit gives you a direct, rigid connection between the pump and motor without the complications of misalignment or improvised hardware. It's a straightforward, purpose-built solution that saves installation time and protects both the pump and motor from the kind of wear that comes from poorly matched components.
What makes this kit stand out is that it's a genuine OEM part, meaning it's designed specifically to work with Oberdorfer's own pump lineup. Whether you're maintaining an industrial fluid transfer system, replacing a worn adapter on an aging installation, or building a new close-coupled pump assembly from scratch, the 4Ad45T gives you the correct fit the first time. The close-coupled design keeps the assembly compact and eliminates the need for flexible couplings or separate bearing housings, which translates to fewer points of failure and easier long-term maintenance.

Frequently Asked Questions
Q: What is the Oberdorfer 4Ad45T Close Coupled Adaptor Kit used for?
It is used to mount an Oberdorfer pump head directly to a NEMA-frame electric motor in a close-coupled configuration. This creates a rigid, compact pump-motor assembly without the need for flexible couplings or a separate bearing housing.
Q: Is the 4Ad45T an OEM Oberdorfer part or an aftermarket component?
The 4Ad45T is a genuine OEM part manufactured by Oberdorfer Pumps. Using the original manufacturer's adapter ensures proper fit, alignment tolerances, and compatibility with Oberdorfer's pump series.
Q: How does a close-coupled adapter kit differ from a flexible coupling or pedestal mount setup?
A close-coupled adapter attaches the pump head directly to the motor's face, eliminating the need for a separate shaft coupling, pedestal, or additional bearings. This results in a more compact assembly with fewer moving parts and reduced vibration risk.
Q: Can this adaptor kit be used with three-phase motors?
Close-coupled assemblies using this type of adapter can accommodate both single-phase and three-phase NEMA motors. When using a three-phase motor, the installer should verify correct rotation direction before full system startup, as reversing two leads will change motor rotation.
Q: Is this part suitable for replacement on an existing pump installation, or only for new builds?
The 4Ad45T is appropriate for both. It is commonly used as a direct replacement for a worn or damaged adapter on an existing Oberdorfer pump installation, as well as for new pump-to-motor assemblies where a close-coupled configuration is preferred.
