South African businesses face a range of water treatment challenges that often require problem-solving. Allmech, leading South African manufacturer of boilers and supplier of water treatment equipment and chemicals, has announced a series of product updates for 2026 aimed at improving reliability, efficiency and system simplicity in high-volume and high-hardness water environments.
According to Allmech managing director, Lionel Maasdorp, the most significant development for the local market is the introduction of Runxin’s new F153 ceramic disc filter and softener valve. With a capacity of up to 70 m3 per hour, it is the largest valve in Runxin’s range to date.
“Many industrial and agricultural applications require very high flow rates,” Maasdorp says. “Until now, we often had to place multiple valves in parallel to achieve the required volumes. A single high-flow valve simplifies system design, reduces the number of vessels and components and improves overall reliability.”
The move to ceramic disc technology is also a deliberate response to performance challenges experienced with piston-operated valves in demanding conditions. Factory testing has shown that the disc configuration offers improved durability, and Runxin has indicated that existing piston valves will be converted to disc valves as part of a broader focus on long-term reliability.
Maasdorp says that another key addition is the F118 multi-functional flow control valve, designed for areas with high groundwater hardness. The valve allows operators to choose between up-flow or down-flow regeneration, as well as regeneration using hard or softened water. This flexibility is particularly valuable in regions with high calcium concentrations, such as parts of the Northern Cape, Limpopo and Mpumalanga.
“Being able to regenerate with soft water helps ensure full resin capacity, while up-flow regeneration can reduce salt usage,” Maasdorp explains. “These are practical advantages for customers operating in challenging water conditions.”
Beyond valves, Runxin has also introduced updates to valve control systems, including printed circuit boards that enable feedback via an RS-485 port. This opens the door to improved monitoring and system management, particularly for larger installations. A new range of low-pressure irrigation valves, pressure-reducing valves and high-flow refill solutions is also available.
In parallel, Allmech is expanding its value-added offering to include flowmeters, vessels, non-return valves, pressure-reducing valves and consumables. “Our goal is to give customers access to a reliable, well-matched range from a single supplier,” Maasdorp says. “This reduces complexity, shortens lead times and supports better system performance. These developments reflect Runxin’s ongoing innovation and our shared focus on practical, affordable water treatment solutions. For our customers, it means simpler systems, improved reliability and more options for solving real-world water problems.”
Allmech was founded in 1995 and has grown over two decades to become one of South Africa’s leading boiler manufacturers and suppliers to the water treatment industry. The company offers a comprehensive range of electrical, gas and oil-fired boilers with corresponding water treatment solutions.
With a customer base stretching from its head office in Benoni, Gauteng, throughout southern Africa and beyond, Allmech has become recognised as an experienced end-to-end provider for clients requiring boiler plants, steam supply of all types, cooling towers, water treatment equipment and associated chemical programmes. Aside from sales to direct and distributor clients, the company’s services include technical support, repairs and maintenance, and spares sales.
Allmech is also the only authorised South African agent for Runxin valves, produced by Wenzhou Runxin Manufacturing Machine Co. headquartered in China.
