Horizontal agitator Flygt 4660

electrically-powered

Rated motor power range of 7.5 – 11.2 kW and thrust range of 800 – 3100 N Propeller diameter of 0.580 m (22.8 in) Compact, robust direct-drive 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 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. Engineered to generate maximum thrust with minimal use of energy, the propeller blades, with their backswept design, allow highly fibrous material to pass through, while the wide-hub design deflects fibrous material. It is possible to increase mixer efficiency by up to 15% in water, and even higher in viscous liquids, with the optional jet ring, while further reducing energy consumption.
