Reliable 32V Bronze Centrifugal Pump Solution for Fluid Circulation Applications
The Oberdorfer Pumps 172B-A87 is a bronze centrifugal pump and motor assembly designed for dependable fluid circulation where corrosion resistance, compact construction, and consistent performance are required. This 32V DC pump features a rugged bronze pump body, a corrosion-resistant 316 stainless steel shaft, and a close-coupled 1/10 HP motor configuration.
With 3/4 inch NPT inlet and outlet ports, the Oberdorfer 172B-A87 provides efficient circulation performance with flow capability up to 13 GPM and a maximum pressure rating of 7 PSI. Its centrifugal impeller design supports reliable movement of water and compatible fluids in cooling, circulation, and equipment systems.
Although commonly used in marine environments, this pump design is also suitable for broader industrial and OEM applications where a compact 32V bronze centrifugal circulation pump is needed.

Frequently Asked Questions
Q: What type of fluids can the Oberdorfer 172B-A87 pump handle?
A: The pump is designed for water, cooling fluids, and other compatible non-abrasive liquids commonly used in circulation systems.
Q: Is the Oberdorfer 172B-A87 only intended for marine use?
A: No. While it is widely used in marine cooling and circulation systems, it can also be used in industrial, OEM, and equipment circulation applications.
Q: What makes the bronze construction beneficial?
A: Bronze provides strong corrosion resistance and durability, making it suitable for environments where exposure to moisture and demanding operating conditions is expected.
Q: What is the difference between a centrifugal pump and a gear pump?
A: A centrifugal pump uses an impeller to create fluid movement and is typically used for circulation and higher-flow applications, while gear pumps are positive displacement pumps designed for controlled flow and pressure applications.
Q: Does this pump include the motor assembly?
A: Yes. The 172B-A87 is supplied as a bronze centrifugal pump and motor unit with a 32V DC motor configuration.
