Grindex

The company that is Grindex today was founded in 1940 by engineers Kristensson and Grähs, who named the company after themselves. It was located in Ulvsunda, north-west of Stockholm. The first product line consisted of ignition mechanics for the Swedish navy. After WWII ended, production was refocused to brakes for carts and wagons.

In the mid 1940s the company developed a grinding machine for workshops. This paved the way for the next breakthough invention, a rock drill grinding machine called the Grindex Rockmaster. This machine first established Grindex’s presence in the construction and mining industries, and is the foundation for today’s Grindex.

When Börje Kristensson was out selling the grinding machine, he came across a new product on the market, a submersible drainage pump. The submersible pump concept was revolutionary. However, there were some drawbacks with the pumps at that time; they were heavy and could not run dry. Kristensson listened to the pump users, then set about developing a lightweight pump that could run dry, thanks to the patented air valve.
