Stations engineered to the duty point
System curve, pump and motor selection, and redundancy. Several pumps in parallel follow demand and keep the station running while one is being serviced.

Pumping and irrigation in Benguela and Lobito
Water supply, industry and farming in a province where water has to be found, treated and moved a long way: pumping stations, borehole fields and irrigation systems.
Since 1968
The SILGAR name in pumping and irrigation.
Six leading brands
Caprari, Flygt, Lowara, Grundfos, KSB and Sulzer.
Hydraulic design
System curve, duty point and surge protection.
Commissioning support
On site or remote, agreed for each project.
What we supply
Borehole fields and submersible pumps
Submersible pumps and motors for deep boreholes, rising mains, cables and panels. From a single borehole to the borehole field of a town or a farm.
Surge and hydraulic protection
We assess the surge risk on long mains and specify protection: air valves, surge vessels and slow-closing non-return valves.
Head stations
Pumping, filtration, fertigation, valves and control in one engineered package. The head of the system is where irrigation gains or loses efficiency.
Filtration
Sand, disc, mesh and hydrocyclones, chosen for the water and the emitter. We work with LAMA, Azud, Amiad, Arkal and STF.
Automation and remote control
Controllers and farm-management platforms, so that a few people can run many sectors (Agrónic and VEGGA).
What shapes a project in Angola
Benguela province is coastal and arid. Water comes mainly from the Catumbela river and from boreholes, and near the coast it turns brackish. Lobito, with its port, concentrates industry and logistics, and the city of Benguela is growing at a pace that calls for new pumping stations. Irrigated farming exists in the Catumbela valley.
What we design for
- Brackish water near the coast: resistant materials
- Little rainfall: irrigation depends on the Catumbela river and boreholes
- Corrosion in a marine setting: coatings and materials
- Power: generator or hybrid solution
Typical applications
- Supply to Benguela, Lobito and Catumbela
- Industry and port logistics at Lobito
- Irrigation in the Catumbela valley and the coastal strip
- Boreholes in brackish-water zones near the coast
Brands we work with
We choose the brand for each duty — flow, head, water and climate — not the other way round.
Caprari
Borehole submersible pumps and high-flow pumps, of Italian origin.
Flygt
Submersible pumps and mixers for wastewater, drainage and process.
Lowara
Multistage pumps, pressure-boosting sets and submersible pumps.
Grundfos
Pumps with integrated drives, pressure-boosting sets and borehole pumps.
KSB
Large pumps for water, industry and supply.
Sulzer
High-flow pumps for water, wastewater and industry.
We also work with: Calpeda · DAB · Ebara · Pentax · Saer · Rovatti · LAMA · Azud · Amiad
The brands mentioned belong to their respective owners. NextGreen is not an official distributor of any of them: we supply equipment from several brands, chosen for each installation.
How a project runs
From first contact to commissioning, in five steps.
Brief
Flow, head, water source and quality, available power and site conditions.
Hydraulic design
System curve, pump selection and duty point, surge protection and control concept.
Proposal
Datasheets, curves and an equipment list, ready for your designer and your client.
Supply
Export packing and logistics. Delivery terms (Incoterms) are set out in the proposal.
Commissioning and support
Start-up support, on site or remote, and a spare-parts plan.
Our own installations, in Portugal
We do not show projects we have not done. These are NextGreen installations in Portugal.
Frequently asked questions
What size of project do you take on?
Stations with several pumps in parallel, variable speed and automatic control: from a town booster station to an irrigation scheme or an industrial water system. Send us the duty (flow and head) and we will tell you plainly whether we are the right supplier.
What do you need to prepare a proposal?
Flow and head (or the system curve), water source and quality, main length and diameter, available power, ambient temperature and project location. If a figure is missing, we help you estimate it.
What do you need to prepare a proposal?
Area and crop, water source and quality (an analysis, if there is one), available flow, elevation difference, available power, and a plan or location of the plots.
Which pump brands do you work with?
Mainly Caprari, Flygt, Lowara, Grundfos, KSB and Sulzer for the larger duties, and others for the smaller ones. We choose the brand for each duty. We are not an official distributor of any of them.
