Series AG-350 Top-Entry Agitator
VQ-AG350
Flange-mounted top-entry agitator with a helical bevel gear unit and a hydrofoil impeller set, for blending, suspension and heat transfer duty in vessels from 1 to 40 m³.
- POWER
- 0.37 to 45 kW
- VESSELS
- 1 to 40 m³
- SPEED
- 30 to 400 rpm
- MOUNTING
- DN150 to DN300
Why it is specified
Sized on the process result rather than on the motor: blend time, solids suspension or heat transfer, whichever the duty actually is. The shaft and impellers are selected together so the critical speed sits clear of the running speed, which is the calculation that gets skipped and then breaks shafts.
Typical applications
- Blending and homogenising
- Crystalliser agitation
- Neutralisation tanks
- Solids suspension
- Storage tank roll-over
Options and executions
- ATEX zone 1 execution
- Double mechanical seal with a barrier fluid pot
- Folding impeller for installation through a manway
- Mixing calculation issued with the quotation
- Steady bearing at the vessel floor
- Variable speed drive with a process speed set point
