What we offer as a Leading Agitators, Mixing Tanks and Vessels
An Agitator is a machine used in tanks or vessels for mixing various process media including, liquid, gases & solids (powders, granules, etc.). It is used for mixing / stirring the material as per process requirements. It works by rotating an impeller to impart energy to the media, which interact and mix.

Vessel or tank with Agitator
Vessels with Agitator is one of the most demanded products that we offer as per the requirements of our customers. We manufacture complete vessel assembly which includes structure, agitators and gear box assembly. These equipment are strong and sturdy in nature. They ensure longer functional life and offer high level of performance efficiency.
What are Agitators?
The components of an agitator, in general, are the motor & gearbox, shaft & impellers and a tank or vessel. Agitators are used in industries to process products in the chemical, food, pharmaceutical, and cosmetic industries for mixing liquids together to promote the reactions of chemical substances keeping homogeneous liquid bulk during storage to increase heat transfer (heating or cooling)
As a whole, the tank fits into the stand, which is generally a C type base. Then the material inside is stirred and mix into the tank by the agitator.
Construction and working principle of an Agitator mixing system
There are two major components of an agitator mixer.
The Agitator or Stirrer – It has three major components – a shaft with impellers, a mechanical seal, and a motor with a gearbox option. The mechanical seal has several options depending on the duty – single/double mechanical seal, dry or wet mechanical seal, gas lift-off mechanical seal related to the duty involved. An agitator shaft is connected to the drive unit (motor & gearbox) and where the impellers used for the mixing are welded or bolted onto. Generally, they are fitted on a stand with mechanised lifting and lowering systems.
The mixing Tank – The agitator or stirrer is mounted onto the tank, vessel or reactors which stores the material.
What is the use of a helical impeller?
Helical impellers can be used where very high viscosity (above 100,000 centipoise) is involved.
It’s important to select the right one in terms of numbers of flight, pitch and helix to suit the specific requirements of the process parameters. The Helical Impeller for high viscosity applications also promotes surface renewal and heat transfer.
How do we select Agitators?
The agitator’s choice depends on the phase(s) that needs to be mixed like liquids only, liquid and solid, liquid and gas, or liquid with solids and gas. Depending on the type of phase and viscosity of the bulk, the agitator can be named mixer, kneader, dough mixer, amongst others.
The agitators used in liquids can be placed on top of the tank in a vertical position, or horizontally (on the side of the tank), or less commonly, the agitator is located on the bottom of the tank.
Agitators can be simplified into Bottom Entry Agitator, Side Entry Agitator, and Top entry Agitator depending on the application’s duty & scale to be mixed.
In the chemical, pharmaceutical & water industries, most Agitators are a Top Entry Agitator. A Top Entry Agitator’s main advantages are handling a more considerable variance in viscosities and specific gravities and that the mechanical seal is not in the liquid.
Based on the material to be stirred and tank ability, the capacity of the agitator’s mixer is selected. In propeller type stirrers, the motor is mounted directly on the stand. The agitator shaft is coupled directly to the motor. The motor and stirrer rpm will be approx. 960 rpm or 1440 rpm.
The plate on the stand allows you to fix the motor quickly into the gearbox. The heavy-duty stand takes loads and balances the motor with the gearbox. The anchor/ paddle agitator is mounted on the gearbox shaft directly through flange coupling.
In this case, the tank/vessel is brought below the stand, and the agitator is lowered into the vessel for stirring. In anchor type stirrers/agitators, it is difficult to have a manual lowering and lifting system for high Hp motors. Hence pneumatic or hydraulic lifting and lowering systems are preferred.
