The pipe system, also known as vacuum system, is placed underneath the shallow manure channels. Similar to a bathtub, the inlet nozzles of the system are closed by plugs. For discharging the manure out of the stable the plug has to be pulled up and the slurry will flow through the pipe directly into the receiving pit. The system is suitable for pure pig slurry.

Advantages

• Low building costs and a good stable climate due to the shallow manure channels
• Short construction times due to shallow channels
• Economic efficiency concerning investment and operation
• Considerable reduction of fly population and pollutant gases, therefore beneficial for animal health
• Wear-free and durable, made of plastics material without mechanical parts
• Fast and optimized draining
• Many customer references from Germany and abroad
• Pumps can be used for dry setup

Our product recommendations

• Submersible motor pump PTS (pig and cattle slurry)
• Thick matter pump DGP (cattle slurry)

Central discharge of manure with closing/opening valves

Below ground level underneath the channels, PVC pipes (200 mm) and specifically developed tees with different connection diameters are to be laid.
The pipe ends are delivered pre-cut – there is no need for cutting in situ.
The closing valve is equipped with a socket branch. The valve is located at the end of the channel. When closed, it holds back the liquid manure, whereby the manure channel is going to fill up with pig slurry.

The risk of formation of hydrogen sulfide when liquid manure is set in motion makes it essential to ensure that the storage of the slurry in the channel should not exceed 14 days.
After opening the valve by lifting an especially designed plastic ball inside, the liquid manure is conveyed by suction out of the channel into the manure pit until the channel is completely empty.
The opening of the valve should take place every 14 days because hydrogen sulfide may form after a period of about 17 days having a bad impact on animal health.

Due to years of experience, we surely know the exact lengths and widths to accomplish a fully operational manure channel, depending on the livestock species.

In most of the stables the manure does not flow by itself. Also, you do not know whether the system will work with reliability. In order to ensure operational safety, flushing lines are placed in each manure channel, starting from the receiving pit, which serve to flush the channels.

These circulation systems are also referred to as channel refilling.

Flushing lines improve hygiene, e.g. washing away fly larvae.

Our product recommendation

• Submersible motor pump PTS (pig and cattle slurry)
• Thick matter pump DGP (cattle slurry)
   

The term slalom system or meander system is used when all of the slurry channels underneath the stable are connected with each other, thus forming an endless system. With this, the entire quantity of liquid manure can be circulated by just one agitator.

In any case, electric agitators with timer are necessary to stir as often as needed to avoid floating layers.
Because: floating layers don’t go around the corner.

The installation kit (mixer tunnel) is available in stainless steel. There are no galvanized parts in the manure transition area.

The submersible agitators AT-Mix and TBM are equipped with large wings at low rotational speed. This increases efficiency especially when handling thick cattle slurry.

Lagoons are foil-lined ground basins. This type of manure storage is popular with large farms in Eastern Europe and Russia.

The investment costs are low depending on soil conditions and environmental regulations. In Germany, the restrictions vary in each federal state. They are continuously updated.

Increasing demands are made on agitation technology because lagoons, for the most part, cover an extensive area or show large footprints.

Due to the large surface, a great amount of rainwater is being collected and the emissions are rather high. Covering the lagoons with floating foils is possible.

The largest lagoon to be agitated, which we have been in charge of, was 70 meters wide, 120 meters long and 12 meters deep.

We do not offer the construction of lagoons.
