FB 10F-150BC/4 Motore sommerso 10'' 400V/690V - Bronze
10'' FB Rewindable water filled bronze-alluminium submersible motor - 10F150BC/4 - 150.0HP Y/D 400V/690V 220.0A 50Hz - Star / Delta Start PE2 + PA Winding - 4 Poles 1450Rpm
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.
CHARACTERISTICS OF THE PRODUCT:
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”.
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 45N-1.4462 which is highly resistant to corrosive attack and mechanical stresses caused by the pump body. 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 compensation for balancing the internalexternal pressure of the motor
The cable, elastomeric reticulated mixture, of EPR type for foodstuff use, certified KTW, WRAS and ACS 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, ensures
storage of the motor to -15°C.
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.
