The single impeller centrifugal pumps series DS are composed of a impeller support shaft, to allow the activation of the pumps coaxial way or through straps with electric motors, diesel or gas engine, of power from 13HP to 85HP.
The pumps of the series DS are characterized by flow rates ranging from 350 to 2500 liters/minute and with head from 5 to 80 meters.
The multiple impeller centrifugal pumps series E are composed of two or three impellers and the considerable number of models available allow to individualize the type of pump that more can meet to the required operating conditions.
The pumps series E are composed of a high endurance cast iron base and of a rotating shaft in steel at chrome-nickel treated with hard-chrome coated socket.
The pump shaft is driven by double-balls bearings, oil lubricated, suitable for bears radial and axial efforts. The hydraulic group that guarantees an elevated performance, is composed of various dynamically balanced radial impellers with special shapings of the blades and diffusers, contained by a flange with aspirant opening on which is housed the auto lubricated bronze bushing of support of the shaft.
