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.

Large pumping stations in South Africa
Hydraulic design, supply and commissioning support for pumping stations with several pumps in parallel, variable speed and automatic control — for water supply, industry and irrigation.
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.
Variable speed and control
Drives, soft starters, electrical panels, pressure or level control and telemetry. The station follows demand instead of throttling the discharge.
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.
Wastewater and drainage
Submersible pumps and mixers for lift stations, stormwater and wastewater, with Flygt and Sulzer.
Spares, documentation and training
A recommended spare-parts list with the proposal, operating manuals and operator training, remote or on site.
What shapes a project in South Africa
South Africa has a highly professional irrigated agriculture (citrus, grapes, pecans, vegetables) in a semi-arid country with recurring drought and water restrictions. The grid faces scheduled outages, which weighs on pumping decisions: storage, solar and variable speed are part of the design. It is also a market with demanding technical standards and well-established local suppliers.
What we design for
- Power outages: storage, solar and soft start
- Demanding standards and technical documentation
- Abrasive water in mines: suitable materials
- Local suppliers: we complement, with engineering and specific equipment
Typical applications
- Transfer and booster stations for municipalities and industry
- Mining and mineral processing
- Stations with storage and solar support
- Boreholes for farms and supply
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
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.
Do you supply equipment only, or engineering as well?
Both. We size and select the pumps, motors, drives and control. Installation is normally carried out by a local contractor, with our technical support.
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.
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 about spare parts and service?
We recommend a spare-parts list with the proposal and ship it with the equipment. We support commissioning and operation on site or remotely, as agreed for the project.
