What KSB does

KSB SE & Co. KGaA is a German manufacturer of pumps, valves, and related aftermarket services, founded in 1871 and headquartered in Frankenthal. The company is publicly listed on the German SDAX exchange (ticker KSB3:GR) with operations spanning more than 150 countries across five continents, and employed 16,838 people as of 31 December 2025. Its portfolio is organised into three business segments: Pumps (€1,618M FY2025 sales revenue), Valves (€404M), and KSB SupremeServ aftermarket services (€1,013M); consolidated FY2025 sales revenue exceeded €3 billion for the first time at €3,035M with €252.1M in EBIT (8.3% margin) and €166M in net profit.

The core technology stack centres on hydraulic engineering, materials science, and additive manufacturing. Flagship products include the Eta standardised water pump series (introduced 1935–36, the company's identity-defining product), the new-generation Omega 2 dry-installed axially split casing pump, the AmaCan D submersible pump, the SEZ F fish-friendly tubular casing pump, and main reactor coolant pumps weighing 100+ tonnes with 8 MW power ratings for nuclear power plants. Manufacturing incorporates metal 3D printing at the Pegnitz facility, achieving 60%+ productivity gains and 40% build-time reductions per part. Digital capabilities are anchored in KSB Guard, an IoT sensor-to-cloud monitoring service, and a 47% controlling stake in ai-omatic solutions, a Hamburg-based AI start-up providing predictive maintenance analytics that extend monitoring from individual pumps to entire industrial plant fleets.

KSB operates an enterprise field sales go-to-market model through its own sales organisations, regional subsidiaries, and authorized service partners across water, energy, mining, petrochemicals, building services, and general industry verticals. Pricing is quote-based for custom engineered solutions, with multi-year contracts typical for large industrial and municipal customers. Service revenue is monetised through spare parts, installation, inspection, and recurring KSB Guard subscriptions tied to a 50+ year pump installed base. India is a key strategic market, where KSB holds a regulatory monopoly as the only approved domestic manufacturer of main nuclear pumps for the country's Indigenous Pressurized Heavy Water Reactor programme, supported by the 2023 acquisition of Bharat Pumps.
