Discontinued model. Request documentation and help selecting a suitable alternative for your existing installation.
Top-entry process agitator
Flygt 4850 is a top-entry process agitator using a geared drive and vertical shaft. Its mounting arrangement differs from submersible-motor mixers. The published 50 Hz table lists 2.2–7.5 kW motor power and 1.5–2.5 m impeller diameters. The number and position of impellers are chosen for circulation in sludge storage, anaerobic treatment or biogas tanks. Tank support structure and shaft dimensions are important when assessing an existing installation.
Final performance and suitability are verified for the selected model and duty point.
UNDERSTAND THE APPLICATION
A solution for your application.
Application areas
Sludge digestion and storage tanks · Anoxic and anaerobic biological treatment · Agricultural biogas tanks
Selection considerations
Determine thrust and positioning from tank dimensions, liquid level and solids concentration. Motor power alone is insufficient for selection.
Share tank dimensions, liquid level, temperature and solids concentration with our technical team. We can assess thrust, mixing objectives and installation together.
