Always ready

for action

Whether its a production run of millions or just a single item: Grahneis GmbH production is always done using reproducible parameters. This guarantees consistently high quality and efficient production.

For Grahneis, every production series starts with a single item. On a day-to-day basis, it is not important how many of each article are produced, rather the quality of each individual one counts. This is why each individual article is treated as if it were unique – whether it is a pump diaphragm that weighs barely a gram or the check valve for piping systems which is 100,000 times heavier.

Well-grounded technical expertise on the composition and processing of materials as well as the usage of today's machines and methods ensure that even small batch sizes result in profitably produced end products – and ensure that these products are able to pass a critical inspection at any time. And according to international standards. The Grahneis GmbH is certified according to the ISO 9001 quality standard.
