Rotor mixer 4500

continuousfor liquidswater treatment

Overview
Flygt's mixer range includes the Flygt 4530 from the 4500 series, designed for mixing in activated sludge processes, sludge retention tanks and digesters. The 4530 is suited where a standard low-speed mixer's impeller diameter is too large but more space is available than for a compact mixer. Compared with direct-drive compact mixers, the Flygt 4530 can deliver over 50% energy savings at similar thrust.

Advantages

• Innovative rotor design: thin-section profile with oblique, strongly backward-curved, double-curvature blades for stiffness, high efficiency and reliability.
• Standard single guide rail installation: compatible with mounts used for mixers on single guide rails; no special pedestals required, facilitating replacement of compact mixers with the 4530.
• Proven drive unit: electric motor with impregnated stator (insulation class H) coupled to an appropriate gearbox, based on Flygt low-speed mixer design.

Applications

• Activated sludge processes
• Sludge retention tanks
• Digesters
