AFS celebrates first year – launches manufacturing plant

THE Abrasive Flow Solutions (AFS) team celebrated the company’s first year of business recently (March 2022) with the official launch of 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 expand its fluid technology services in Africa. 

“The AFS team works closely with our sister company BMG, to extend specialist services, through the design, distribution, supply and support of a broad range of slurry-related valves, including Klep diaphragm and wedge gate valves,” says Donald Morrison, General Manager, AFS. “Our specialists successfully achieved their first challenge, which they set for themselves when the company was established – to improve the quality of diaphragm valves, by extending service life and reducing the maintenance requirements of this range. This goal was achieved through hard work and the implementation of advanced design technologies, materials and coatings and is a great tribute to our team.

“Important milestones over the last year include the establishment of a new rubber lining facility, with the installation of autoclaves that have capacities of up to 10m in length. 

“Another advancement is a new pinch valve sleeve manufacturing facility enabling the manufacture of all pinch sleeves, including high pressure and pneumatic sleeves. We have also made a significant investment to extend our hydraulic pressing facility and through our new design and process, we are able to manufacture high-pressure diaphragms capable of pressures in excess of 20 Bar.

“AFS has enhanced the design and production of its slurry knife gate valve range, with dimensions ranging in diameter from 50mm to 1,5m valves. The range includes flanged, wafer, lugged, urethane lined and high-pressure knife gate valves. 

“BMG also distributes a locally manufactured range 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 recently manufactured and factory-tested some larger DN 700 hydraulically operated 20 Bar valves for a customer in Europe.

“Recently launched Dual rotary disc sleeve valves comprise an advanced 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 through heavy slurries without sticking. Wafer, flanged and high-pressure variants are available.

This AFS portfolio is particularly well-suited for use in harsh conditions in diverse industries, including mining, chemical and petrochemical, water and wastewater, energy production and agri-food industries. Important installations recently, have been in mining slurry, tailings dams, and acid pumping applications, which rely on plant availability and the safe operation of valves.

Another achievement for AFS is that ESG has recently achieved recognition as a Level 2 contributor to Broad-Based Black Economic Empowerment (B-BBEE), which means customers can claim BEE procurement recognition of 125 % against all purchases.
