This is the B3B Circulating Pump. It is part of our B series micro centrifugal pumps.  A brushless DC motor powers the B3B Circulating Pump. This pump is quiet, compact and lightweight.

It has a seal-less design to prevent leakage. The B3B has a wide range of working voltage. This provides a stable performance for the pump. It has a high temperature resistance and is made with food grade materials.

The B3B is designed for general applications and also commercial and industrial applications. These pumps are ideal for all circulation pump applications. Also, they will pump fresh water, seawater, and other liquids that are compatible with the pumps materials and that are of similar viscosity to water.
