Horizontal agitator Flygt 4650 LSPM

electrically-powered

Rated motor power range of 5 – 8.2 kW and thrust range of 900 – 2400 N Propeller diameter of 0.580 m (22.8 in) Compact, robust direct-drive motor Line-start permanent magnet (LSPM) motor Active Seal™ for zero leakage Non-clogging, fiber-handling hydraulics Low-cost installation Designed for high reliability and low energy costs Flygt compact mixer components have not only been engineered for reliable operation and efficient mixing, but to reduce energy costs as well. Xylem's Flygt squirrel-cage induction motor is manufactured for durability and dependability. Stator windings are trickle impregnated in resin and rated at Class H 180 degrees C (355 degrees F) for excellent resistance to overheating. The line-start permanent magnet (LSPM) motor combines the efficiency of a synchronous permanent magnet motor with the direct on-line starting of an induction motor. This saves on current-related costs, such as for cables and power supplies, and up to 20% on energy compared to conventional induction motors. The Flygt plug-in seal features the Active Seal system for zero leakage into the stator housing. Laser-cut grooves on the inner seal faces act as a micro-pump to force any liquid present on the drive-unit back to the buffer fluid side. The seal housing with the barrier fluid helps lubricate and cool the seal, ensuring efficient heat transfer even when running dry.
