HERMETIC-Pumpen

What HERMETIC-Pumpen does

HERMETIC-Pumpen GmbH is a privately-held, family-owned German manufacturer of hermetically sealed pump technologies, headquartered in Gundelfingen, with roots tracing to the 1866 founding of the LEDERLE mechanical workshops and the 1956 launch of the HERMETIC canned-motor-pump product line. The company designs and manufactures canned motor pumps (Spaltrohrmotorpumpen), magnetically coupled pumps, liquid ring vacuum pumps, and hermetically sealed submersible pumps, organized into a pre-configured V-Line and an engineered-to-order E-Line. Its proprietary ZART® (Zero Axial and Radial Thrust) design philosophy and magnetic support bearing technology underpin a product envelope spanning fluid temperatures of -160°C to +480°C, system pressures up to 120 MPa, and motor outputs from 1 kW to 690 kW — the broadest range of canned motor pumps in the market per the company's claims.

The company sells engineered-to-order hardware to large industrial operators across chemical, petrochemical, oil & gas, refrigeration/HVAC, railway, power generation, and food & beverage verticals, with specialized offerings for CO2/LCO2 and CCUS applications (CAMh refrigerant pumps, EC 1935/2004 food-grade compliance) and a new push into the civil nuclear market via an October 2025 technology partnership with KSB SE & Co. KGaA. Revenue is generated primarily through custom-quoted new-equipment sales complemented by recurring streams from original spare parts (12-month warranty), maintenance and service contracts, repair and overhaul, and 24-hour hotline support. Distribution is conducted via a global subsidiary network (China, USA, France, Czech Republic, Poland, Singapore, Spain) and authorized service partners spanning 43+ countries, with no public revenue disclosure.

With approximately 400-440 employees at the German headquarters and a wider global footprint, HERMETIC holds ISO 9001 (since 1994) and ISO 14001 certifications, API 685 and ATEX compliance for hazardous areas, and consecutive Great Place to Work certifications across four country operations. The business is managed by the Krämer family with Nicolaus Krämer as Managing Partner and Sebastian Dahlke as Managing Director, with no external investors, parent company, or public listing evident in the data.
