When it comes to practical farming technology built for African conditions, PFS Power Factor Systems has quietly been doing something rather impressive.
Since setting up shop in Nelspruit, Mpumalanga back in 1998, the company has grown into a trusted name across the continent, serving farmers in countries ranging from South Africa and Zambia to Kenya, Angola and beyond.
At the heart of what PFS offers is the VSD Starter, a variable speed drive designed and built entirely in-house and purpose-made for irrigation systems. It is not a generic piece of kit adapted for farm use. Every feature on this machine was thought through with the farmer in mind, from the automatic priming function to the gradual pipe filling sequence that protects pipelines from sudden pressure surges.
Dry pump protection and current limiting come as standard, meaning the system constantly keeps an eye on motor performance and shuts things down before any costly damage can occur. A safety switch input adds another layer of control, and can be connected to external devices like a GSM modem for remote operation or a float ball to manage dam levels automatically.
What really sets the VSD Starter apart is its flexibility. Seven programmable pressure settings mean farmers can deliver precisely the right pressure to different fields without relying on mechanical pressure regulating valves. Pair that with seven auto-irrigate programmes and you have the ability to run up to 49 scheduled irrigation cycles every week, all managed through a clean and intuitive touch screen interface.
Electricity costs are a very real concern for farmers across the region, and the VSD Starter addresses this head on. Running at 97% efficiency and drawing only the power needed to maintain the selected pressure, most users see a full payback within 9 to 14 months. The Eskom tariff control feature allows the pump to run exclusively during off-peak periods, cutting costs even further.
A tamper-proof event history log records every action with a time and date stamp, giving farmers complete visibility over their irrigation activity and making any troubleshooting straightforward.
