G209T3C2-L30AA0 7003208 Faggiolati Pumps Pump

Shafts grided down in ball bearings and mechanical seals seats, over-dimensioned respect to standard parameters of use. Motor asynchronous threephase squirrel cage type, insulation class H(180°C). Dry motor, cooled by surrounding liquid. Protection degree IP 68. The motor is projected for continuous or intermittent operation, with a maximum of 15 starts per hour at regular intervals. The motor is projected for working with 5% maximum voltage unbalance between phases. Ball bearings overdimensioned, life lubricated, maintenance free. Oil chamber oil lubricates and cools the seals and emulsifies eventual water infiltrations. This electric pump has two types of seals for a perfect insulation between the electric motor and the pumped liquid. Upper seal: Ceramic/Graphite. Lower seal: mechanical, silicon carbide. Impellers are projected in order to guarantee and assure an high hydraulic efficiency and low power consumption, they have big inter-blades and diffuser free passages, minimum blades number, special blades design, especially diffusers’ water-cutter blades designed to avoid filamentous materials catching. APPLICATION Submersible electric pumps with channels are used prevalently for the lifting of non corrosive dirty waters also with solid bodies in suspension. In particular for screened waste water and drainage of places subject to flooding, crude and activated sludge. CONSTRUCTION DATA Submersible electric pumps, robust in construction, watertight electric motors accommodated in compartment, connected, by shafts of reduced lengths, to the impellers situated at the pump casing by the interposition of oil chamber between the hydraulic side and the electric motor.
