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.

4” high-yield, water filled canned submersible motors, totally made of stainless steel AISI 304 (for the parts in contact with the water). The use of high-quality materials highlights the electrical and mechanical properties of the motors. The stator, 24-slot lamination made, hermetically sealed and resin filled by means of a vacuum process. This procedure guarantees: - great mechanical strength, in case the motor is dipped in deep wells; - maximum electrical isolation; - excellent heat exchange; - the motor to work perfectly with inverter “Inverter Resistant”.

A series of rewindable submersible standard water lubricated motors with high performance, over sized and extraordinarily simple to maintain. Completely “MADE IN ITALY”, NEMA standard and made to meet environmental provisions. Thrust bearing, the real heart of the submersible motor, is of “Michell” bidirectional type with pads in treated steel and supported by a disk in resin compound fibres and self-lubricating additives, fully ecological. The union between these materials withstands impacts and exceptional axial thrusts for greater efficiency and safety.

4 submersible electropumps, series FB4, are for clean water for 4” wells DN100. The extraordinary simplicity in the construction, the performances given from the anti wear floating impellers and the easy installation guarantee a high quality product, long-lasting in the time.

6 pumps range FB6R, are for clean water for 6” wells DN 150. The suction support and the delivery bowl are in micro-cast stainless steel AISI 304. To assure greater safety to the pump, even in the deep wells (more than 40 bar) a new system has been projected to lighten the pressure on the impellers: a single pump becomes a group of two pumps in series, named FB6R.../...D.

The stator, 24-slot lamination made, has been thought to obtain maximum electrical performance and it is hermetically sealed. 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 winding, asynchronous type, studied to work perfectly also with inverter “Inverter Resistant” type. 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 stator, 24-slot lamination made, hermetically sealed and resin filled by means of a vacuum process. This procedure guarantees: great mechanical strength, in case the motor is dipped in deep wells; maximum electrical isolation; excellent heat exchange; the motor to work perfectly with inverter “Inverter Resistant”.

6” Rewindable Water Filled Stainless Steel AISI 316 and Duplex Submersible Motors. A series of high-yield rewindable water filled stainless steel AISI 316 and DUPLEX submersible motors, oversized and extraordinarily simple to maintain. They are completely “Made in Italy”, NEMA standard and made to meet environmental provisions.

4” submersible pumps, range FB4, are for clean water for 4” wells DN 100. The extraordinary simplicity in the construction, the performances given from anti wear oating impellers and the easy installation guarantee a high quality product, long-lasting in the time.

6” pumps mixed-flow type, range FB6S, are for clean water for 6” wells DN 150. This pumps have mixed-flow impellers with diffusers combined on each stage. They may be chosen when high capacity and medium-low head are needed.
