Starting from the 90s, the Group pursued growth beyond the piston pumps, through the acquisition of several leading companies manufacturing professional and industrial cleaning machines, and electric motors.
In 1996, Interpump Group was listed at the Milan Stock Exchange (Borsa Italiana).

Between 1997 and 1999, the Interpump Group entered the hydraulic components sector through the acquisition of several companies, becoming the world’s largest producer of power take-offs (PTO). In a move to reposition the Group focusing on applications with the highest added value, companies in the cleaning machinery and electric motor divisions were subsequently dismissed (respectively in 2005 and 2011).

With the same strategy, the Group went on with an acquisition campaign of leading companies in both divisions:
- In Water-Jetting, reinforcing the absolute leadership in high/very-high-pressure piston pumps, where higher and higher performances and product innovations dramatically increased the possibilities for applications. Starting in 2015, the horizon in this sector was expanded with the addition of high pressure homogenizers, agitators, many different types of pumps and components for flow handling in the food, cosmetic and pharmaceutical industries.
- In Hydraulics, several producers of cylinders were acquired in 2007-2008; the years between 2013 and 2015 saw the creation of the Valves and DCV sub-division and the beginning of activities in Hoses and Fittings, which was expanded in the following years with flexible metal hoses, rigid shaped pipes, and complex piping systems.

Starting from 2019 activity in power transmission is extended from power take-offs to an increasingly extensive range of reduction gears.

All acquired companies become part of the Group while preserving their brands, organizational structure, and all their success factors, minimizing integration costs and contributing to the economic results of the Group since day one.
