About Hugo Lahme
Hugo Lahme GmbH was founded in 1945 in Ennepetal and is a medium-sized family business in its third generation with around 80 employees. The company produces castings from bronze, red brass, aluminium and stainless steel in its own foundry including core production, and machined to assembly-ready components. In addition to contract casting for customers, Hugo Lahme develops and produces its own products for swimming pool technology – pool hydraulics, underwater lighting, counter-current and massage systems – under the brands FitStar®, AllFit®, VitaLight® and SpringFit®. The value chain includes core shooting, machining, metal impregnation, leak testing, assembly of electronic controls and LED lighting, and quality inspection. Customers come from swimming pool technology, the fountain industry and general metal casting; references include, among others, Europa-Park Rust (Rulantica) and Aqualagon near Paris. Ennepetal is the sole production and sales location.
