Overview

The BH series canned pump is a wet-rotor silent pump with a shielded (canned) motor: sealless, leak-free and quiet. The pump is of vertical inline construction - inlet and outlet have the same diameter on the same centre line, so it can be installed directly in the pipework like a valve. For industrial and municipal water supply and drainage, high-rise building pressure boosting, garden irrigation and HVAC circulation, conveying clear water and liquids similar to water.
