Oberdorfer 820B-07W25 Bronze Centrifugal Pump – 2HP High-Flow Industrial Unit
The Oberdorfer 820B-07W25 is a high-performance bronze centrifugal pump engineered for demanding industrial and commercial fluid transfer applications. Built with corrosion-resistant bronze construction and a stainless steel shaft, this pump delivers reliable operation in environments handling water, oils, and compatible chemicals. Its close-coupled design with a 2HP motor ensures efficient power transmission and compact installation.
Designed for continuous-duty service, the 820B-07W25 provides flow rates up to approximately 97 GPM, making it ideal for circulation, transfer, and process systems. The mechanical seal design enhances durability while reducing maintenance, and the pump operates quietly with minimal vibration. This model is well-suited for systems requiring consistent, high-volume flow without the need for self-priming functionality.
