200QJ submersible pump

The electrical submersible pump series 150QJ,200QJ,250QJ,300QJ,350QJ to 800QJ are semi-axial hydrodynamic impeller and of the diffuser. This configuration enables pumps, with a small diametrical overall dimention, to give high deliverswith medium working heads. The peculiar profiling of the hydraulic pipelines makes these pumps particularly resisting to abrasion made by slightly sandy water. In the constructive version of the standard production, they are suitable to draw water which is chemically and mechanically not aggressive for the component materials. The particular compact and not too much bulky construction, without any seal member on the shaft, offers a reliable operation that doesn`t require any particular maintenances, as the bearings of the pump are lubricated by the pumped liquid.
