About STORM
August Storm GmbH & Co. KG, headquartered in Spelle, is an OEM-independent service provider for combustion engines of all common makes in the power range of 100 to 7,000 kW. The company reconditions engines, engine components, crankshafts, engine blocks, main bearing seats, pumps and gearboxes for stationary energy systems, marine and mobile drives, construction machinery, locomotives, special vehicles and industrial plants. In its machining operations, crankshafts up to 8 m in length are ground, main bearing seats up to 11 m in length are line-bored, components from 8 to 700 mm in diameter are honed, and plain bearings and special parts are manufactured in-house; metal spray coating complements the reconditioning process. Further focal points are the maintenance of piston compressors for the chemical, refining and natural gas industries, service for injection pumps and injectors on Bosch-certified test benches, and the reconditioning of turbochargers. With more than 350 employees at 14 branches and service points in Germany, the Netherlands and Austria, as well as a 24/7 service hotline, the company ensures short response times and worldwide deployment. The company can look back on more than 80 years of experience in engine reconditioning and is certified as a member of the Quality Association of Engine Reconditioning Businesses in accordance with RAL-GZ 797.
