Pumps manufacturer Ingersoll Rand will extend its capabilities in wastewater treatment with the acquisition of SSI Aeration and its subsidiaries.

SSI designs and manufactures wastewater treatment plant equipment with approximately $30 million in annual revenue. Its product portfolio is focused on “innovative and energy-efficient” engineered membrane diffusers including fine bubble diffusers, coarse bubble diffusers and aeration systems.

See MDM’s Investment Bank Directory for a rundown of the key investment banks and advisory firms in the distribution sector. 

The acquisition will enable Ingersoll Rand to combine several technologies like low pressure compressors with SSI’s aeration offerings to provide a comprehensive, end-to-end solution, company officials said in a Feb. 3 news release.

With manufacturing facilities in the United States, South Korea and India, SSI will join the Industrial Technologies and Services segment.

“Inorganic growth remains a key part of our company’s overall growth strategy in 2025,” Ingersoll Rand CEO and Chairman Vicente Reynal said. “We look at potential acquisitions through the lens of how they will help us optimize our solutions, and we look forward to growing our presence in the wastewater treatment market with the addition of SSI.”

In October 2024, Ingersoll Rand also made deals in the U.S. Italy and India.
