Then and now

1965: Founding of Company

The starting roots of altek are founded upon the innovative spirit of two engineers and two operators from the company Rau, who didn´t want to resort on the competitor´s pumps for their field sprayers. So in 1965, in the garage of one of the company founders, the development and manufacturing of the first altek pumps took place.

1970: Construction of the first Operations Building

The quantities produced started growing in demand so they founded in 1970 the first altek operating building. A few years later the uprising market share the products had reached required the company to expand.

1992: Rau Group goes into Bankruptcy

During the 80s the market suffered a negative impact causing the majority of farmers to fall victims to the structural change.
