en.Wedoany.com Reported - Sandvik has signed an agreement to acquire Diemme Filtration, a manufacturer of high-performance filter presses. Diemme will be reported as a separate new division—the Filtration Division—under Sandvik's Rock Processing business area.

Through this acquisition, Sandvik enters the filtration and dewatering sector, thereby enhancing the supply capabilities of its Rock Processing business across the entire mining value chain. The total addressable market for this business is estimated at over $2 billion. Filtration is a key process step in downstream mining, and Diemme's solid-liquid separation solutions help improve productivity, water recovery rates, and tailings management.
In addition to engineered-to-order filtration systems, Diemme also has a substantial aftermarket business with significant growth potential. The company also offers proprietary software for remote monitoring and predictive maintenance, which complements the digital offerings of the Rock Processing business.
Stefan Widing, President and CEO of Sandvik, stated that this acquisition fully aligns with the company's strategy to grow in attractive niche areas of downstream mining. He noted that through Diemme, the company adds a profitable and rapidly growing mineral processing niche to its core product portfolio, which strengthens its position among key mining customer groups and brings an attractive aftermarket business.
Demand in the filtration sector is driven by several strong trends, and the market is expected to grow at a low double-digit rate. Declining ore grades lead to increased slurry volumes at mine sites, substantially boosting the need for filtration capacity. Additionally, stricter water and tailings regulations are driving demand for water conservation solutions and denser tailings.
Richard Harris, President of Sandvik Rock Processing, stated that Diemme's products are highly complementary to the Rock Processing business, positioning the company strongly in a critical area of mining customers' future processes. He added that this directly supports the company's strategy for eco-efficient rock processing and brings opportunities to increase aftermarket penetration by leveraging Sandvik's global service network.
Diemme is headquartered in Lugo, Italy, with advanced manufacturing facilities and R&D capabilities. The company employs approximately 200 people and had estimated revenue of around $110 million in 2026. The transaction is expected to close in the third quarter of 2026.
