Wernert-Pumpen

What Wernert-Pumpen does

Wernert-Pumpen (WERNERT-PUMPEN GMBH) is a fourth-generation family-owned German manufacturer of centrifugal and axial pumps constructed entirely from non-metallic materials, headquartered in Mülheim an der Ruhr. Founded in 1920 by engineer Karl Wernert, the company pioneered the world's first plastic centrifugal pump in 1927 and has specialized continuously in corrosive, abrasive, and toxic media handling since then. Its product portfolio is built around five core standardized series — NE (EN ISO 2858 chemical pump with mechanical seal), NM (magnetic coupling chemical pump), SP (high-flow process pump up to 2,500 m³/h for FGD applications), VKPF (vertical wet-immersion pump), and NKPF (vertical dry-installation tank pump) — supplemented by specialty variants including the TAIFUN hermetically double-sealed pump, RO elbow pump, FK close-coupled pump, and a patented grinding pump. Underlying technology rests on proprietary materials including WERNIT® armoured mineral cast, UHMW-PE, PVDF, and PTFE, along with patented bellows mechanical seals (since 1952) and magnetic coupling isolation shells; the entire range carries ATEX T3/T4 certification for explosive atmospheres and the company has held ISO 9001 certification uninterrupted since 1994.

The company's go-to-market is bifurcated by geography: a direct enterprise field sales force covering four German regions (NORD, WEST, SÜD, OST) with technical offices in Oberhausen, Augsburg, and Leipzig, staffed by trained mechanical engineers; internationally, it sells through a network of certified premium distribution partners covering more than 50 countries. Revenue is generated predominantly through hardware sales of custom-engineered and standardized pumps, supplemented by spare parts supply, in-house repair/overhaul services, and on-site field assembly. Pricing is project-based and not publicly disclosed. Target end markets are chemical processing, environmental protection and flue gas desulfurization, steel manufacturing, and surface treatment/plating — all vertical segments requiring safe handling of aggressive media where metal pumps are unsuitable.

Wernert operates as a traditional German Mittelstand company with no external investors, no venture capital, and no disclosed revenue or headcount. Its largest single recorded order was 61 pump units for the Amager Bakke waste incineration plant near Copenhagen (2014, via LAB SA), and it has supplied flue gas cleaning pumps for five coal-fired power plants. Manufacturing is concentrated at its Mülheim an der Ruhr headquarters, expanded in 2010 with a new assembly hall.

Recent moves3 records

Broad incumbents

• Flowserve Corporation: Large US-listed broad-line pump and valve manufacturer with chemical-process, FGD and slurry pumps that overlap Wernert's SP process pump offering. Competes via global service network rather than plastic-specialist expertise.
• Grundfos Holding A/S: Danish global pump manufacturer with industrial and chemical dosing pump lines overlapping Wernert's chemical and dosing applications at the higher-flow end of their industrial portfolio. Far broader product line and scale.
• Alfa Laval AB: Swedish broad-ingredient industrial equipment supplier with chemical-duty centrifugal pumps and hygienic/sterile process pumps. Overlaps with Wernert in chemical-industry verticals but offers a much wider equipment portfolio.
• Xylem Inc. Global water and process pump manufacturer with chemical/industrial offerings overlapping Wernert's end markets, though typically in metallic rather than plastic centrifugal pumps. Large-scale, post-acquisition consolidation play (Flygt, Wedeco, Evoqua) competing for the same chemical plant wallet.

Direct peers

• KSB SE & Co. KGaA: German-headquartered global pump manufacturer producing a broad range of centrifugal pumps, including chemical and process variants, with comparable geographic reach and customer overlap in European chemical/industrial markets. Most direct large competitor to Wernert on home turf.
• Richter Chemie-Technik GmbH: German specialist in lined and plastic centrifugal pumps for the chemical industry with directly overlapping product philosophy, EN ISO 2858-compliant standardised pumps, and similar customer base in European chemicals/FGD. Closest niche competitor.
• Sulzer Ltd. Swiss industrial group with a deep chemical-process pump portfolio that directly competes with Wernert's standardised chemical pump (NE/NM) and process pump (SP) families in corrosive-media and FGD duty worldwide.

Emerging players

• Speck Pumpen Vakuumtechnik: German industrial pump manufacturer adjacent in size and specialization, with plastic centrifugal and process pump options serving overlapping chemical and environmental customers in Europe.
• Verder Holding (Verder Liquids / Thomas / Watson-Marlow): Specialty pump group whose Watson-Marlow and other chemical/industrial pump brands serve overlapping aggressive-media and dosing-process applications in European chemical/environmental plants. Smaller end of comparable channel structure.
• IDEX Corporation (Viking Pump, Pulsafeeder): US-listed diversified industrial group including metering, chemical and specialty pump brands (Pulsafeeder, Viking) competing in the corrosion-resistant chemical-dosing and process-pump niche that intersects Wernert's NE/NM/FK family.
