Serigstad has developed and delivered agricultural equipment since 1864, and been leading in digital ensiling equipment for forage conservation for over 25 years.
We understand the importance of successful conservation, in the aquaculture industry as well as in agriculture. We have flexible and reliable equipment, ensuring precise addition of additives with intelligent control and pumps with different capacity.
The daily collection of dead fish from fish farms reduces the potential of contagions in the pens and in nature and gives an overview of the general health of the penned fish. The result is better environment in the pens, and benefit both the farmed fish and the different types of cleaner fish.
Dead fish, fish trimmings and by-products from production is milled and the result is fish silage. To avoid disease, contamination and wild scavengers, it is important to conserve the fish immediately. By adding an ensiling agent, the bacterial growth in the silage is stopped, and the silage can be stored over time. The silage is circulated to ensure uniform pH and achieve the best possible quality.
The quality of the silage is the deciding factor in what happens next; good quality silage can be sold, while low or bad quality silage must be paid for and disposed of as special waste.
The daily addition of dead fish requires daily addition of ensiling agent to ensure a stable pH. A large quantity of bones neutralises the acid and leads to an increase in pH. It is therefore important to regularly measure the pH, as well as when transferring the silage to a storage tank.
If the pH rises above a certain threshold the silage will begin to rot and the quality of the silage will decrease; to counter this more ensiling agent will be required, as the rotting will increase the pH. On the other hand, too much ensiling agent can decrease the pH below the desired levels and be costly in the long run.
With ensiling products from Serigstad Agri, ensiling agent is easily added with a touch on the screen and desired amount can easily be adjusted. The solution has a digital flowmeter for precise dosing, and an electric shut-off valve to prevent dripping.
The diaphragm pumps can deliver from 3 liters/min to 12 or 17 liters/min respectively. They come equipped with a filter on the pump-side which removes small particles that could be in the ensiling agent. The pump is mounted with the flowmeter and shut-off valve in a stainless steel chassis, for a complete integrated solution. The riser is selected based on the type of container for the ensiling agent, either a 200 liter barrel or a 1000 liter IBC.
The gear-pumps have a flow from 0,5 liters/min and up to 5 or 8 liters/min, respectively. They have the unique ability to reverse the flow through the pump, allowing the unused ensiling agent to be returned to the container from the hose.

SmartFlow takes care of the ensiling and frees the user to focus on other tasks. Signals for starting and stopping the pump is obtained from the ISO-system in the tractor. SmartFlow regulates power to the pump to ensure correct amount every time. Integrated components and wireless communication simplifies installation and reliability.
The MP series are diaphragm pumps capable of high capacity and high pressure. It is suitable for use on big machinery, like self-propelled harvesters.
