The electric pump mod. MM 100/125 for 65 and 130 T/h with horizontal split casing consists of a pumping body of the centrifugal type and of two opposite impellers. The division of the body is on the horizontal plane in order to reduce the axial thrust to minimum and to simplify maintenance. The electric motor is an asynchronous three-phases type, connected to the pump by means of an elastic coupling mounted on a frame structure which is made of electro welded steel. The special balancing of the pump and the specific construction of the base determine the sturdiness of the unit which permits to reduce to a minimum the structural noise level transmitted to the hull. Normally, the base is fixed to the hull after having introduced four resilient blocks which filter the noise transmitted by high frequencies.

Testing carried out according to the standards shown in table UMM 1008, May 1984 edition, of Navalcostarmi: inspection and checking of integrity, test of hydrostatic pressure, test of voltage applied between electric phases, performance test, test of sealing and alignment, endurance test over 700 hours with more than 100 start-ups, test of operation in inclined position, detecting of self-induced vibrations and structural noise, impact and mechanical ambient vibration test, test of performances after impact and vibrations, disassembling and restoring. In particular these tests have been carried out according to the program transmitted by Mariperman from La Spezia, at which the delegates of Maripernam and Navalgenarmi of Turin attended.
