About KLAAS Group
KLAAS Maschinenbau GmbH & Co. KG, headquartered in Wetter (NRW), was founded in 1975 and manufactures pipe swivel joints, rotary unions and swivel joint scissor links for the transfer of liquid and gaseous media, with pivoting and rotational movements of up to 360°. Through the sister company KLAAS Verladetechnik GmbH & Co. KG (KVT), loading arms, access solutions and hose loading systems have been produced for 20 years – over 750 standard and over 1000 individual loading arms. In addition to loading technology, the company offers contract manufacturing: CNC milling and turning, sheet metal processing, all welding processes as well as special expertise in the gear shaping of internal ring gears and hollow gears. Materials are steel, aluminium and stainless steel, manufactured from one-off production to series production. Customer industries include the chemical industry (also ATEX zones), oil and gas, food and beverages, pharmaceuticals, water management as well as transport and logistics. According to its own statements, over 9000 projects have been realized.
