Hose pumps of the DULCO®flex DFDa series

The pump housing is filled with glycerine to reduce friction. A ball-bearing rotor ensures a high level of smoothness and long life. The DFDa delivers flow rates up to 17,500 l/h at backpressures up to 15 bar in tough industrial applications. For pumps of the series DFDa, the option vacuum device in the pump housing can support the restoration of the hose’s shape. This improves the suction behaviour and provides for a steady delivery of viscous media.
