Highly efficient submersible agitators
from 1 to 18.5 kW


For more than 30 years, streisal GmbH has been working on the use of submersible agitators in process technology applications. The technical performance, reliability and energy efficiency of our agitators has always been at the centre of our thinking and actions.

The standard equipment of streisal submersible motor agitators includes the mechanical seal in highly wear-resistant silicon carbide that is protected against corrosion in a stainless steel holder, as well as temperature monitoring in the motor winding and a high-volume oil chamber with seal monitoring.

Installation can be on flexible lowering devices or fixed stand units. As a result, all kinds of tank geometries can be used at any time without difficulties.

Moreover, it is possible to adapt the design of the installation accessories to special installation situations.


A wide range of individual components (submersible motors, gearboxes, propellers, monitoring devices and accessories) allows an appropriate submersible agitator to be configured for any application. This increases the efficiency, ensures a long service life of the agitator and reduces energy costs.


TSR submersible agitators with step-down gear unit

The robust TSR submersible motor agitators are designed to be an efficient solution for a wide range of technical agitating tasks.


Hybrid submersible agitator TSRL

Perfectly suited for mixing and flow generation in biogas tanks with relatively high dry matter contents and substrate temperatures up to 60 °C.


Slow-running submersible agitators ATP/BTP with step-down gear unit

Slow-running streisal submersible motor agitators of the ATP/BTP type enable large quantities of fluids to be circulated gently. With large diameters and low speeds, these agitators generate maximum thrust with the smallest possible energy consumption.


Compact TRV submersible agitators with direct drive

Universally applicable submersible motor agitator featuring an extremely compact design and stainless steel housing to open up entirely new applications.
