What Erich Stallkamp ESTA does

Erich Stallkamp ESTA GmbH is a privately held German manufacturer founded in 1973 by Dipl.-Ing. Erich Stallkamp and headquartered in Dinklage, Lower Saxony. The company designs, manufactures, and distributes stainless steel equipment — tanks, pumps, agitators, and separators — for four end markets: agriculture (slurry and manure handling), biogas plants (fermenters, digestate storage, mixing and separation), industrial and process wastewater (paper mills, beverage companies, chemical plants, food production), and municipal wastewater treatment. Stallkamp pioneered stainless steel tanks for agricultural liquid manure storage in 1984 and stainless steel biogas fermenters in 1999, and has expanded its product portfolio into Continuous Stirred Tank Reactor (CSTR) digesters up to 15m in diameter and 20m in height using duplex stainless steel.

The company operates from a 46,000 m² production facility in Dinklage with approximately 200 employees and is DIN EN ISO 9001:2015 certified. Its technology stack centers on stainless steel fabrication, corrosion-resistant engineering (including duplex steel 1.4462), and mechanical innovation such as the award-winning Cutting System (2019 Biogas Innovation Prize) and press screw separators. Stallkamp distributes through direct sales from headquarters, 40+ national dealers in Germany including BayWa AG, and 40+ international distributors covering 70+ countries across Europe, Asia, the Americas, and Oceania. The wholly-owned Polish subsidiary (Erich Stallkamp Polska Sp.z.o.o., founded 1998) supports Eastern European markets; a prior Chinese subsidiary (ESTA Machinery Manufacturing Tianjin) was dissolved in 2011 and production consolidated back to Germany.

Revenue is generated primarily through one-time hardware sales across the four product lines, supplemented by paid diagnostic, repair, and maintenance services (EUR 250 diagnosis fee, EUR 150 cleaning fee, 20% restocking fee, 12-month warranty). Pricing is quote-based and EXW, with net payment terms of 14 days and pass-through clauses for cost increases on contracts longer than 3-6 months. Stallkamp co-founded WELtec Bio Power (2001) with WEDA for turnkey biogas plant delivery and acquired the Nock GmbH separator division in 2017. The company remains founder-controlled, with Erich Stallkamp and Christoph Heseding as co-managing directors, and has no disclosed external investors or public listing.
