Tedima

What Tedima does

TEDIMA GmbH (legal name: Technische Dichtungen, Maschinen und Anlagen GmbH) is a privately held, family-owned German manufacturer of customized, high-precision industrial shaft seals, headquartered in Krefeld, Germany. Founded in 1983 by Kurt H. Kiparski after four decades at a global sealing-technology company, the business is now run in its second generation by his sons Kurt R. Kiparski and Ralf Kiparski. Its core products fall into five families: MultiSeal thermoelastic lip systems, RotaSeal chamber (KD) and housing (GD) seals, TEdiFLON Supra HP and TediFlex PTFE gaskets, the 3D-Logic-Seal digital gasket workflow, and the Advanced Hygienic Sealing Technology line for sterile applications. Supporting offerings include custom mechanical seals, TWB-2 shaft sleeves, and engineering/repair/maintenance services.

The technology stack rests on proprietary PTFE-based materials (TEDEX-B and TEDEX-W thermoelastic compounds, multidirectional TEdiFLON Supra HP variants) and a CAD/CNC-driven 3D-Logic-Seal process for patient-specific flange gaskets, all manufactured in-house on a Mazak/Unisign/Reckermann CNC machine park with 100% pre-shipment quality control. Performance envelopes documented across product lines include temperatures from -240°C to +600°C, pressures from high vacuum to 300 bar, pH 0–14 chemical resistance, TA-Luft leakage to 10^-7 mbar*l/s*m, and peripheral speeds up to 150 m/s. Certifications (ATEX, FDA, EU 1935/2004, EU 10/2011, TA-Luft/VDI 2440, TÜV, BAM, DVGW, EHEDG Aseptic/Hygienic CLASS I) anchor entry into chemical, pharmaceutical, food, environmental, mechanical-engineering, and mining verticals.

The business model is enterprise-direct, custom-engineered, and quote-based. All seals are designed and produced to customer-specific requirements; pricing is not publicly disclosed and contracts run on multi-year replacement cadences. TEDIMA generates revenue from one-time sales of custom-manufactured sealing solutions and from engineering, repair, and maintenance services. Go-to-market is a personalized field-sales motion supplemented by trade-fair presence (POWTECH Nuremberg 2025/2026, Cibus Tec Parma 2026) and a downloadable-catalog website; no distributor or reseller channels are referenced, and served markets are concentrated in the DACH region.

Products and services

• MultiSeal Standard Thermoelastic high-performance radial shaft seal with stainless steel housing (1.4571) and TEDEX seal lip. Available in single lip, double lip (back-to-back, tandem), and dust lip configurations. Used as an alternative to mechanical seals and braided packings for high pressure, high speed, high temperature, aggressive media, and dry running applications.
• MultiSeal Special Customizable single and double-lip seal solutions with dimensionally standardized configurations for special applications where MultiSeal Standard cannot be used. Available in various TEDEX material grades.
• MultiSeal Set of Lips Ready-to-install seal lip set consisting of TEDEX seal lip and static seal for installation situations where standard MultiSeal cannot fit. Used where installation conditions or construction reasons prevent standard product use.
• Universal Shaft Seal High-performance shaft seal produced without metal housing, consisting of fabric-reinforced elastomer, PTFE-modified seal lips, and stainless steel garter spring. Used in heavy machinery and shipbuilding applications such as rolling mills, power transmission, propeller shafts, and water turbines. Available in split and endless versions.
• RotaSeal GD-2 Split housing shaft seal with 3-piece radially cut seal rings. Suitable for fans, blowers, compressors, mixers, centrifuges, gears, and steam turbines. Operating range from high vacuum to 30 bar pressure, -190°C to 600°C, up to 150 m/s sliding speed. Available in low-pressure (ND) and high-pressure (HD) versions.
• RotaSeal GD-5 Sliding 3-piece carbon seal ring for blowers, agitators, dryers, mixers, and fermenters. Features adjustable seal rings with overlapping gastight joints, easy mounting/dismounting due to split housing, and low leakage even at different operating temperatures.
• RotaSeal KD-3 High-performance shaft seal with modular system design for small and medium-sized fans, blowers, compressors, and bearing seals. Chamber, barrier gas, grease chamber, and intermediate chamber elements assembled via axial screw connection. Multi-part radially cut seal elements held by garter spring.
• RotaSeal KD-4 HD Labyrinth seal with solid chambers and radially flexibly mounted multi-segment seal rings held by garter spring. Suitable for dry running turbines, compressors with subcritical and supercritical rotors. Reduces leakage values by up to 90% compared to rigid labyrinth seals.
• RotaSeal KD-8 HD

Quantifiable outcome

• Leakage reduction of up to 90% compared to rigid contact-free labyrinth seals with RotaSeal KD-4 HD and KD-8 HD chamber seals
