MOTOR CHARACTERISTICS:

4” high-yield rewindable oil filled submersible motors in AISI 304.

The use of high-quality materials highlights the electrical and mechanical properties of the motors.

The stator, 24-slot lamination made, has been thought to obtain maximum electrical performance and it is hermetically sealed.

The winding, asynchronous type, studied to work perfectly also with inverter “Inverter Resistant” type.

The external sleeve and bottom cover are in stainless steel AISI 304 to avoid the corrosion when these parts are in contact with the water.

The upper support, G25 cast iron with electrophoresis treatment and
protected by a stainless steel top cover.

The upper and lower ball bearings, duly oversized to assure long
life to the motors.

The rotor shaft, carbon-steel alloy in the rotor area. The protrusion is in stainless steel AISI 304 up to 3 hp; from 4 hp to 10 hp it is in stainless steel DUPLEX that guarantees an excellent mechanical resistance, which is absolutely necessary with very high starting torque.

The mechanical seal is in graphite/ceramic. The particular form of the lodging of the mechanical seal guarantees higher seal to the motor.

The cable (approved KTW, ACS, WRAS) is equipped with a special connection plug studied to avoid the climb of the oil along the cable during the operation, besides the connection plug allows an easier substitution of the cable in case a longer one is needed.

The oil inside the motor is food-tested and it is in compliance with the prescription of the Italian Pharmacopeia and approved from the Food and Drug Administration (U.S.A.).
