The Abrasive Flow Solutions (AFS) group celebrated the company’s first 12 months of business recently (March 2022) by internet hosting a two-day launch function at its manufacturing plant in Benoni, Gauteng.
AFS, which specialises in the design and manufacture of slurry-related valves, was established by the Engineering Solutions Group (ESG) of Invicta Holdings Limited, as part of the Group’s strategy to broaden its fluid know-how providers in Africa.
ไดอะแฟรม ซีล works carefully with our sister company BMG, to increase specialist companies, by way of the design, distribution, supply and support of a broad vary of slurry-related valves, including Klep diaphragm and wedge gate valves,” says Donald Morrison, General Manager, AFS. “Our specialists efficiently achieved their first challenge, which they set for themselves when the corporate was established – to improve the standard of diaphragm valves, by extending service life and decreasing the upkeep requirements of this range. This aim was achieved through hard work and the implementation of superior design applied sciences, materials and coatings and is a superb tribute to our staff.
“Important milestones during the last 12 months embrace the establishment of a model new rubber lining facility, with the set up of autoclaves that have capacities of up to 10 m in length. In the rubber business, autoclaves are used to vulcanise rubber products, which aren’t but stable dimensionally, by elevating heat and pressure. An autoclave is similar to a huge oven, with extremely high temperature and strain scores, that make rubber elements stable and strong in dimension and shape.
“Another development is a new pinch valve sleeve manufacturing facility within our new rubber lining and sleeve manufacturing facility.
“We are now in a place to manufacture all pinch sleeves, including high strain and pneumatic sleeves. AFS pinch sleeves are manufactured from the best high quality rubber products, that are provided by Rema Tip Top. We have also made a major investment to increase our hydraulic urgent facility and through our new design and process, we’re able to manufacture high-pressure diaphragms capable of pressures in extra of 20 Bar.
“AFS has enhanced the design and production of its slurry knife gate valve vary, with dimensions ranging in diameter from a 50 mm unit to 1.5 m valves. diaphragm seal contains flanged, wafer, lugged, urethane lined and high-pressure knife gate valves.
“BMG additionally distributes a regionally manufactured vary of abrasion-resistant valves for Dual Products International. These products include pinch valves, new water air release valves, Resilient Seated Gate (RSV) valves and rotary disc sleeve valves. AFS has just lately manufactured and factory-tested some bigger DN 700 hydraulically operated 20 Bar valves for a customer in Europe.
“Recently launched Dual rotary disc sleeve valves comprise a sophisticated rotating gate valve with sleeve design, developed specifically for heavy abrasive and corrosive slurries and water and wastewater installations. This patented design permits the valve to cycle through heavy slurries without sticking. Wafer, flanged and high-pressure variants can be found.
“Our highly expert staff has a radical understanding of the processes where valves are installed and is in a position to specify the correct valves required for every application. We also help customers in solving the problems of inauspicious installations and functions.
“To guarantee optimum safety, efficiency and the prolonged service life of every system, the number of the correct industrial slurry valve is critical. Valve selection relies on varied elements, including the scale and shape of particles, stress, temperatures and chemical content.”

This AFS portfolio is especially well-suited to be used in harsh situations in various industries, including mining, chemical and petrochemical, water and wastewater, power manufacturing and agri-food industries. Important installations lately, have been in mining slurry, tailings dams, and acid pumping functions, which rely on plant availability and the protected operation of valves.
Another achievement for AFS is that ESG has lately achieved recognition as a Level 2 contributor to Broad-Based Black Economic Empowerment (B-BBEE), which means clients can declare BEE procurement recognition of 125 percent towards all purchases.
