Miniature Centrifugal Pumps
BMK3...BMK4

Peripheral impellers

Miniature Centrifugal Pumps
of the BMK series have been desined for clean water circuits of up to 160 degree C fluid temperature and up to 7 bar of system pressure.
The pumps are equipped with a magnetic coupling. The pumps can be mounted vertically or horizontally. The specific design allows the pumps to operate wear poor.
