The Abrasive Flow Solutions (AFS) group celebrated the company’s first 12 months of enterprise recently (March 2022) by hosting a two-day launch perform 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 a part of the Group’s strategy to broaden its fluid technology companies in Africa.
“The AFS team works closely with our sister firm BMG, to extend specialist providers, via the design, distribution, provide and assist 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 problem, which they set for themselves when the corporate was established – to enhance the standard of diaphragm valves, by extending service life and lowering the maintenance requirements of this vary. This objective was achieved by way of hard work and the implementation of advanced design applied sciences, supplies and coatings and is a great tribute to our team.
“Important milestones over the last 12 months embody the institution of a new rubber lining facility, with the set up of autoclaves which have capacities of up to 10 m in size. In the rubber business, autoclaves are used to vulcanise rubber products, which aren’t yet secure dimensionally, by elevating heat and pressure. An autoclave is much like a huge oven, with extraordinarily excessive temperature and strain ratings, that make rubber parts stable and stable in size and form.
“Another advancement is a brand new pinch valve sleeve manufacturing facility inside our new rubber lining and sleeve manufacturing facility.
“We are actually in a place to manufacture all pinch sleeves, together with high strain and pneumatic sleeves. AFS pinch sleeves are manufactured from the best high quality rubber products, which are supplied by Rema Tip Top. We have additionally made a significant funding to extend our hydraulic urgent facility and through our new design and process, we are able to manufacture high-pressure diaphragms able to pressures in extra of 20 Bar.
“AFS has enhanced the design and manufacturing of its slurry knife gate valve range, with dimensions ranging in diameter from a 50 mm unit to 1.5 m valves. The range includes flanged, wafer, lugged, urethane lined and high-pressure knife gate valves.
“BMG additionally distributes a locally manufactured vary of abrasion-resistant valves for Dual Products International. These products embody pinch valves, new water air launch valves, Resilient Seated Gate (RSV) valves and rotary disc sleeve valves. digital pressure gauge has lately manufactured and factory-tested some bigger DN seven hundred 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 allows the valve to cycle by way of heavy slurries without sticking. Wafer, flanged and high-pressure variants can be found.
“Our highly skilled staff has a thorough understanding of the processes where valves are installed and is in a position to specify the right valves required for each utility. We additionally assist customers in solving the issues of difficult installations and purposes.
“To guarantee optimum safety, effectivity and the prolonged service life of every system, the number of the correct industrial slurry valve is critical. Valve choice is predicated on various components, including the dimensions and form of particles, pressure, temperatures and chemical content material.”

This AFS portfolio is particularly well-suited to be used in harsh circumstances in numerous industries, together with mining, chemical and petrochemical, water and wastewater, power manufacturing and agri-food industries. Important installations recently, have been in mining slurry, tailings dams, and acid pumping purposes, which depend on plant availability and the protected operation of valves.
Another achievement for AFS is that ESG has just lately achieved recognition as a Level 2 contributor to Broad-Based Black Economic Empowerment (B-BBEE), which implies clients can claim BEE procurement recognition of one hundred twenty five % against all purchases.
