ELECTRIC SUBMERSIBLE PUMPS SEMISOM/50
TYPE OF THE ELECTRIC PUMP: SEMISOM 900/50 M
TECHNICAL CHARACTERISTICS
Shafts with grinded spots for ball bearings and mechanical seals (1).
Three-phase electric asyncronous rewindable motors with short-circuit rotor, coolant filled so to assure low working temperatures. Windings
with phase insulators to protect the motor from power peaks, as a guarantee of a highly-trustworthy product (2). Resin-insulated cable kit to
prevent penetration of water inside the motor (3).
Double sealing with oil chamber in-between. Silicon carbide and Alumina mechanical seal (4), external packing ring in rubber NBR (5).
High-efficiency impellers (6).
