How does the agitator work?

Tecnapur high-speed submergible agitator

The Tecnapur high-speed submergible agitator homogenises the slurry from the cesspools for pumping to the separator, thus guaranteeing a uniform rate of input flow for optimal solid-liquid separation.  

The Tecnapur high-speed submergible agitator is quick and easy to assemble compared to other models on the market. It is also cheaper, because it does not require expensive building work, external transmission, or concrete supports for the motor. And if farmers spread the slurry from their cesspools onto the fields, the AG-01 prevents the formation of scale on the surface and lifts the solids accumulated at the bottom. So the right mixture of liquid and solid fractions is obtained before being loaded into the tank for spreading in the field as fertiliser.

The Tecnapur high-speed agitator generates a flow of liquid that lifts the solids that have settled at the bottom of cesspools and mixes them until the slurry is properly homogenised for spreading in the field or being pumped to the Separator for solid-liquid separation.


Unlike dry-fitted motors, submergible agitators are highly flexible in terms of position, and can easily be redirected to ensure that the generated flow covers a large distance and adapts to the shape of the container. This optimises the flow produced by the agitator and ensures quick and efficient slurry homogenisation.


The different materials used in the manufacture of the agitator, and its design with self-cleaning blades, guarantee durability and efficiency, even in extreme conditions.
