Adaptation to needs
Each region has its own particularities in terms of water table, soil type and sunshine. It is our job to identify the solutions adapted to each site, in order to ensure the proper functioning and longevity of our solutions.
Systèmes intégrés
We do not leave you alone when it comes to choosing the right product range for your needs. With the help of our approved and certified experts, we advise you to provide the best response to your operational challenges, at a lower cost and for a maximized lifespan.
Civil engineering
In all our offers, we support you in terms of civil engineering and your hydraulic structure. In the case where your pump must be installed in a borehole, we will ask you for the drilling section (protocol) before providing you with a detailed offer. In the same way, we can advise you on the construction or renovation of your wells and/or water tower.
Logistics & after-sales service
Research & Development
We travel all over Senegal to install our customers' solar systems and provide the necessary training sessions. With a general warranty period of 2 years, our customers know that they can count on us and that we are there for them.
Technical data sheets
The (nominal) power of our pumps currently ranges from 0.15 kW to 37 kW, which allows us to achieve maximum pumping heights of 350 m and flow rates of 500 m3/h max.
Our technical department can provide you with information and present all of our products on request.
SEV SARL est constamment en train d'étudier de nouvelles solutions, et d'innover afin de développer et de perfectionner les systèmes pour nos clients.
Performance
Performance
Our way of looking at performance is not limited to simple calculations of litres/hour or m3/day. Indeed, for us this means listening to our customers first and foremost in order to be able to offer them, from a wide range of pumps, the one best suited to their individual situation, the climatic conditions and their needs, depending on their hydraulic structure and the type of crop and irrigation desired.
Why a solar pump?
Why a solar pump?
Our submersible pump systems are used, for example, to supply populations with drinking water , or for irrigation in agriculture . Submerged in a well or borehole, the pump receives power from the solar panels to operate from morning to night.
"No batteries, so no problems!" Indeed, batteries could reduce the overall lifespan of the system! The average lifespan of our pumps is 5 to 10 years! Duration varies depending on several parameters: Water quality, hydraulic structure, preventive maintenance, etc. Do not hesitate to contact us to ask for a quote or a study!
Surface pump systems are mainly used as circulation/filtration pumps in swimming pools , ponds or natural ponds. In some areas such as the river valley, surface pumps can also be used for agriculture, particularly in pivot irrigation .
