McLanahan Corp. said it has signed an agreement to acquire Diefenbach, a manufacturer of filter presses and thickeners based in Medolago, Italy. The two companies, which have been working together on projects since 2013, expect the acquisition to close during the second quarter of 2023.

Diefenbach has been a leader in liquid-solid separation using filter presses since its founding in 1907, when the company was focused on producing presses for the olive oil industry. In the 1950s, Diefenbach expanded into the recycling and filtration of industrial wastewater. Today, Diefenbach has sold thousands of machines and has extensive experience in selling and manufacturing this equipment for the mining and aggregates industries, as well as for chemical manufacturing, food and beverage processing, battery recycling, wastewater treatment and more.

As the focus on a circular economy and recycling water from industrial processes becomes more and more prominent on a global scale, Hollidaysburg, Pennsylvania-based McLanahan was looking for a partner to continue expanding its offerings in this space. This will allow the company to ensure it is able to offer a more comprehensive solution to customers and industries around the world in support of these changing requirements for processing.

“As we look toward the future, we see a growing need for wastewater and tailings management in a variety of industries as part of the circular economy,” said Cory Jenson, executive vice president for sales and business development for McLanahan. “Every industry is being challenged to use less and less water and to recycle the water they are using. This acquisition offers significant synergies to McLanahan’s existing tailings solutions in mining and aggregates, which continue to remain a critical part of McLanahan’s product offerings.”

McLanahan said Diefenbach will continue to operate as an independent brand in the marketplace, focusing on its core industries and markets around the world.
