SIPOS Aktorik

What SIPOS Aktorik does

SIPOS Aktorik GmbH is a German manufacturer of electric rotary, part-turn, double-motor, and nuclear-rated actuators for industrial valve automation, headquartered in Altdorf near Nuremberg. The company was established at the end of 1999 when Siemens AG's Electric Actuators subdivision was spun off as an independent entity, transferring all employees, know-how, documentation, and production facilities to the new company. The firm positions itself as a niche specialist claiming approximately 100 years of accumulated industry experience inherited from its Siemens heritage, and operates as part of the AUMA Group distribution ecosystem.

The company's product portfolio centers on electric actuators supporting OPEN-CLOSE, inching/positioning, modulating, and continuous duty operations, with specialized variants for pressurized water reactor (PWR) nuclear applications. Complementary offerings include actuator controls, industrial communication systems, and add-on components. SIPOS holds nuclear safety certifications (KTA 1401, KTA 3504) alongside ISO 9001, 14001, 45001, and 50001 management system certifications, plus EAC and SCC credentials, which collectively constitute meaningful regulatory and quality barriers in its target verticals: water/wastewater, power generation, nuclear energy, and oil and gas.

SIPOS generates revenue through hardware sales of actuators and related components, with an 80% export quota indicating heavy international orientation. Distribution is executed via direct enterprise field sales from German headquarters combined with the AUMA Group's global subsidiary and representative network covering approximately 97 countries. The company employs roughly 35 staff at its Altdorf headquarters (with total headcount reported in the 51-100 range), reflecting a lean manufacturer that leverages a parent group's channel infrastructure to reach enterprise customers worldwide. Pricing is quote-based and not publicly disclosed, consistent with engineered industrial equipment sold into project-driven specifications.
