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.

Features of the product in stainless steel AISI 316
The 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 and self-lubricating additives, fully ecological. The union between these materials withstands impacts and exceptional axial thrusts for greater efficiency and safety.
The supports, upper and lower are in stainless steel AISI 316 in compliance with W.Nr.1.4408 and ASTM a 351 CF8M rules, this material allows the motor to work properly even if it is dip in aggressive and corrosive waters.
The stator is covered by a sheet in stainless steel AISI 316 (W.Nr.1.4404) that withstands corrosive attack and stray currents.
The windings, of asynchronous type, are:
• for the “F” series in copper wire with insulation in PVC.
• for the “F…C” series in copper wire with insulation in PE2 + PA, suggested for high temperatures, surges in tension and “Inverter Resistant”.
The rotor shaft is particularly strong, guided by pilot bush anti- wear bearings in graphite. The terminal “ribbed” part of the shaft is in Duplex (W.Nr.1.4462) which is highly resistant to corrosive attack and mechanical stresses caused by the pump.
By grinding the entire shaft the rotor takes on a concentricity such as to ensure perfect linearity. With balancing, a shaft free from vibration is obtained.
The mechanical seal, fitted in series, “SIC-SIC” silicon-silicon carbide and ensures optimum sealing even with sandy water.
The membrane ensures the compensation for balancing the internal-external pressure of the motor.
The cable, elastomeric reticulated mixture, of EPR type for foodstuff use, certified WRAS, ACS and KTW for drinking water.
The filler liquid, clear water with addition of propylene glycol specifically studied to safeguard primary waters. It performs the function of cooling, antioxidant and antifreeze, it ensures storage of the motor to -15°C.
The bolts and screws, simple things but not to be underrated, these are in AISI 316 stainless steel, well worked so as to avoid detachments from corrosion in the long term.

6” REWINDABLE WATER FILLED BRONZE-ALUMINIUM SUBMERSIBLE MOTORS
A series of rewindable submersible water filled motors with high performance, oversized and extraordinarily simple to maintain.
The BRONZE-ALUMINIUM used in this range displays the highest resistance to corrosive attack and is thus indicated for seawater and brackish water. 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.
The supports, upper and lower, are in bronze-aluminium in compliance with ASTM B148 C958.00 rules, ensures resistance to corrosive attacks much greater than standard bronze.
The stator is covered by an AISI 316 stainless steel sheath that withstands corrosive attack and stray currents.
The windings of asynchronous type are:
• for the “F” series in copper wire with insulation in PVC
• for the “F..C” series in copper wire with insulation in PE2 + PA, suggested for high temperatures, surges in tension and “Inverter Resistant”.
