Side entry mixers, engineered and built in Pune, India +91 95035 00333sales@fluidmixtech.com

Side entry mixers, engineered for your tank

Also called side entry agitators, they mount on the tank wall, so the drive stays at ground level. Each one is sized for your tank and your process, and made to order in our Pune works.

Why a side entry mixer?

On a tank that is wide compared with its height, a side entry mixer usually does the job with less installed cost than a top entry agitator.

No roof structure

Nothing hangs from the roof, so floating roofs and light cone roofs need no bridge or reinforcement.

Short shaft

The shaft only reaches a short way into the tank, so it stays stiff, light and inexpensive.

Ground-level service

Motor, drive, bearings and seal are all outside the tank and reachable without cranes or roof access.

Whole-tank circulation

The jet along the floor sets the whole tank circulating, which blends it and limits settling.

Common questions

What is a side entry mixer?
A side entry mixer (or side entry agitator) is a mixer that enters a tank through a nozzle in the side wall near the bottom, instead of hanging from the roof. The motor and drive stay outside the tank at ground level. The impeller throws a jet across the floor that sets the whole tank circulating, which blends the contents and limits settling.
Where are side entry mixers used?
They are used where tanks are large and a top-entry agitator would need a long shaft and a heavy roof structure. FMT supplies them for oil and gas storage, FGD limestone slurry, milk storage, edible oil, pulp stock chests, water and wastewater, distillery tanks, and CBG and biogas digesters. Suitability depends on the actual tank and process.
How many side entry mixers does a tank need?
It depends on tank diameter, liquid height, product viscosity and what the mixer must achieve. Small tanks often need one unit; large crude oil tanks commonly use two to four mixers grouped on one side of the shell. We work this out from your tank data and tell you the number, size and motor power.
Can a side entry mixer be fitted to an existing tank?
Yes. It needs a flanged nozzle on the lower shell. If your tank does not have one, a nozzle can be added during a planned shutdown. We give you the nozzle size, elevation and orientation with our offer.
