Miniature Centrifugal Pumps
of the BMK series have been desined for clean water circuits of up to 320° F (160° C) fluid temperature and up to 100 psi (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 without wear poor.
