BM pumps -centrifugal console with a horizontal arrangement of the shaft and axial fluid supply. Designed for pumping paper and wood fiber masses with a solid particle concentration of up to 8%, a hydrogen pH from 2 to 13, with a working environment temperature to 100 ° C. BM pumps are used in the technological processes of pulp and paper production on pulp-paper and cardboard plants.
Work wheel BM pumps -a cast closed five-blade, with chipping blades on the rear disc. There are modifications BM pumps and with half-open wheels, i.e. Without the front disk. In this case, the efficiency of the pump decreases by 40%. Masny BM pumps with half-open wheels are more reliable in the work of high concentration fiber masses. The front seal of the wheel is slit. The drive BM pumps is carried out from the electric motor through the sleeve-jacket coupling with a spacer. Dismantling the pumps for replacing the wheel is carried out without disconnecting the suction and pressure pipelines from the pump and electric motor body from the frame.
The running part of BM pumps are made of stainless steel, resistant in sour and alkaline media. The pumping of the pump, the suction pipe and the front cover, form the pumping of the pump, form the pump housing, in the lower part of which there are paws for its fastening on the frame. A wide absorption pipe provides optimal values of the flow rate of the pumped environment at the entrance to the pump.
