TECHNICAL CHARACTERISTICS Shafts with grinded spots for ball bearings and mechanical seals (1). Thick external casing obtained from wiredrawn tubes, with brushed spots for the mechanical seals (2). 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 (3). Micro thermostat to protect the motor from high temperatures to be wired to the protection/control panel (4). Resin-insulated cable kit to prevent penetration of water inside the motor (5). Mechanical seal in the first chamber in graphite and alumina (7). Probe to detect water ingress in the oil chamber between the two mechanical seals to be wired to the protection/control panel (6). Silicon carbide and alumina external mechanical seal (8). Double-row lubricated and over-dimensioned ball bearings to grant a long life (9). High-efficiency impellers designed to be interchangeable with pumps of the same power (10). Volute with Flygt-compatible guide rail claw (11).
