What Sigma Group does

Sigma Group is a Czech industrial pump manufacturer headquartered in Lutín, Czech Republic, operating under SPL Holding a.s. Founded in 1868 (with its current legal entity formed in 1994 and the holding structure established in 1997), it is the largest pump manufacturer in the Czech Republic. The group operates 10+ subsidiaries across markets including Poland, the broader EU, and selected international territories, with products deployed in 60–76 countries through more than 70 product lines.

Its core offering consists of custom-engineered centrifugal pumps organized into three categories — medium, heavy, and unique — serving capital-intensive process industries where flow reliability and qualification are critical. The portfolio serves nuclear energy (ČEZ nuclear fleet at Temelín and Dukovany), conventional power generation, water management, mining, metallurgy, chemical and petrochemical processing, agriculture, and rescue services. Manufacturing is supported by substantial R&D infrastructure, including what the company describes as the largest cavitation tunnel in the Czech Republic, a 12 MW hydraulic testing laboratory, and a hot testing laboratory under construction. R&D headcount exceeds 70 staff.

The business model is project-based and turnkey, combining engineering, manufacturing, installation, and aftermarket service. Customers are predominantly large state-owned utilities, energy companies, and heavy industrial operators (ČEZ, EDF, ŠKODA PRAHA, Dalkia, PKN ORLEN, ALSTOM, U.S. Steel, Mittal Steel), and qualification-driven sales are supported by an extensive certification stack — ISO 9001 (since 1994), ISO 14001, ISO 45001, ISO 3834-2, AQAP 2110 (NATO), and ISO 19443 (nuclear, achieved in 2021 as the first Czech manufacturer). Revenue is not publicly disclosed, and the group is privately held with no external PE/VC backing identified in the input data.
