Mixing Agitators

Bio-Gen Solutions supply agitators and mixers, specifically designed for biogas plants, agriculture, liquid manure tanks, waste water treatment plants or lagoons. We supply market leading agitation systems from leading European suppliers to ensure we supply best mixing system for particular solutions been delivering agitation solutions for nearly 60 years in the biogas, manure and waste water industry.

Mixing agitator

Our Knowledge and exclusive technology combined with our field-related expertise makes SUMA able to optimize and deliver custom solutions for your business. With SUMA, your results will be efficient liquid manure management and reliable biogas yields.

With a wide range of products for and install we are able to provide the most efficient solutions for your tanking and mixing requirements.

Variety of tanking solutions diagram


The agitator which is vertically or horizontally adjustable up to +/- 30°. There are several models aligned to a variety of requirements allowing custom designed agitation.

Giantmix agitator


The Giantmix has been specially designed to optimize the biological process in digester and after fermenters with almost constant substrate levels, which can be inclined horizontally and vertically.

Installation depth:

Because of the unique SUMA-sealing system, the installation depth of 8 m beneath substrate level but full swivel range is possible.

Sealing system:

The flexible tube feed through gets sealed with 2 EPDM sealing membranes (inside and outside) and a special sealing system of SUMA.

Easy maintenance:

One advantage of the design of the Giantmix is that almost all of maintenance duties can be carried out from the outside, which means that opening the digester or dismounting the unit is not necessary. The drive side with the electric motor and transmission is accessible from the outside; only the shaft tube and propeller are within the fermenter and in an optimal position for thorough mixing.


Submersible, directional agitation, along with high powered flow rates, optional propeller steel, with variety of case options depending on PH levels of liquid.

Optimix agitator


For optimized submersible agitation, across a range of liquids and PH Levels and teperatures. Optimix agitators are available with 4 / 9 and 15 kW allowing for range of rotational speeds of the propeller.

Because of the unique modular design motor performances, gears, propeller and mast sizes can be combined for an customised agitation solution.

Galvanical isolation:

The SUMA-guide mast support with 4 rollers and POM-slide rails guarantee a perfect sliding on the mast and furthermore a galvanical isolation between the mast and the agitator.

Optimum stirring result:

The 3 separated oil chambers for motor, gear and bearing housing ensure a proper stirring. Long life oil with a longer oil changing interval is used for the gear and the bearing housing. The sealing is made through the mechanical seal SiC/SiC within the bearing housing.

Control box:

There are delta-star-operating-switches for a manually operation or time-controlled -soft start control available. All agitators can be managed over an external frequency converter.

Gastight Mast

Height adjusted, agitator guide mast, with innovative cable guidance and cable clips to relieve strain relief.

Gastight mast agitator system


The guide mast with base frame is suitable for tanks with a depths of 12 m. The gas tight ceiling lead through is a developed product optimised for biogas tanks with concrete top or big lagoons with concrete bridge.


The vertically adjustment is made through the external handwheel. The easy adjustment of the horizontal rotation direction is a unique advantage of the GDD.

Cable guidance:

The cable guidance is behind the mast on a Ø 30 mm ss316 guide tube through cable clips.

Long service life:

The MGD is completely manufactured of ss304 and within the gas area of ss316. The GDD is manufactured completely in ss316 (V4A) and is suitable for guide masts of 100 to 150 mm.

High gas-tightness:

The space of the rope lead through a grease cartridge out of POM and special grease. For a gas tightness of nearly 100 % a new seal bushing for the rope lead through was developed which is lubricated with special grease at the installation point, including gas tightness of the service box.

Delivery scope:

Wall support inside and outside the tank, gastight cable- and rope lead throughs, external rope winch with a Ø 8 mm ss316 rope and a handwheel for the vertically adjustment of the agitator. The robust device is delivered with a wideness of 60 cm to the mast (steel tank) or 120 cm to the mast (concrete tank).

Mixing Agitation

Bio-Gen Solutions supply Mixing agitation, across Australia and being Australian Channel partners for Global tanking company CST we chose to supply high quality European agitation systems that work seamlessly within our tanks.

Wastewater treatment

Bio-Gen Solutions supply tank mixing agitators for water and wastewater treatment, concentrating on maximizing flow rate while running with reliable energy output, in order to optimize the mixing process. Using a high torque, low horsepower/kilowatt approach, the energy input is put through our purpose built gearboxes and transmitted to the ideal impeller that is sized specifically for each installation.


Bio-Gen Solutions agitators are especially designed for CST tank digestors, fermenters, secondary fermenters, lagoons and end storage facilities. We can provide specifically designed agitators for a variety of applications, allowing for optimal distribution of liquid substrate maintaining temperature and nutrients within your tank. All mixing is aligned to manageable power output, fully customized height and directional flow rates.


Bio-Gen Solutions supply agitators for agriculture, providing solutions to efficiently mix slurry before application in the field. As manure agitator we offer optimized solutions and as well PTO driven agitators. Find your perfect fitting product. Wether slalom channel, bolted tank, concrete tank or lagoons - we supply products for all applications.
