G272M2P1-G25AD1 7001180 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: lip seal NBR. Lower seal: mechanical, silicon carbide. Impellers are equipped of a special grinder system and are projected for waters and mud coming from agricultural drainages. Grinder system Stainless Steel. APPLICATION Submersible electric pumps with grinder are used prevalently for the lifting of waters and mud coming from agricultural drainages. 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.
