APPLICATION
1~230V - 3~400V versions: coolant filled, asynchronous, rewindable electric AC motor with short circuit rotor. Insulation Class F.
Windings with phase insulators to protect the motor from power peaks, as a guarantee of a highly-trustworthy product.
24V DC versions: with permanent magnets dry electric DC motor. Insulation Class F
Resin-insulated cable kit to prevent penetration of water inside the motor
Shafts machined on ball bearings and mechanical seals location
Double mechanical seal with oil-chamber in-between
