This the B1 Circulating Pump. It is part of our B series micro centrifugal pumps. This pump has only one moving part. Because of its brushless DC motor, the B1 Circulating pump is very quiet. It is also compact and lightweight.  The B Series Pumps include a seal-less design to prevent leakage.  They also have a wide range of working voltage providing stable performance. The B1 is made with food grade materials. Furthermore, it is resistant to high  temperatures.

The B1 Circulating pump is designed for general, commercial and industrial applications. These pumps are perfect for all circulation pump applications. Furthermore, the B Series pumps will pump fresh water, seawater, and other liquids. These other liquids need to be compatible with the pumps materials. Also, they should be of similar viscosity to water.
