Sonnek Engineering

What Sonnek Engineering does

Sonnek Engineering GmbH, headquartered in Vienna and founded in 1930, is a privately held Austrian industrial engineering firm that designs, manufactures, and integrates pump and fluid-handling systems for industrial customers. The company operates through three pillars: (1) Sonnek Anlagenbau (plant construction) encompassing modular Plug & Pump skid/container systems for Enhanced Oil Recovery and produced water injection, water treatment (reverse osmosis with permeate output up to 20 m³/h and yields up to 92%), sludge drying via HARTER heat-pump and DORSET waste-heat technologies, railway toilet water systems, and RoadPump mobile solutions; (2) the VANA sub-brand for food and hygiene solutions including melting plants, chocolate fountains, pigging systems, process and storage tanks, and mixing technology; and (3) Metallbau for pipe, prototype, ventilation, and steel construction. The portfolio is completed by SONNEK Pumpen-Service, a manufacturer-independent repair, maintenance, and reconditioning operation across all pump brands.

The business model is overwhelmingly industrial B2B and project-based, with revenue generated from hardware sales of pumps and modular systems, one-off turnkey integration contracts (design, manufacture, commissioning), and recurring service via pump maintenance plus Operation & Maintenance (O&M) and Build-Operate-Transfer (BOT) models for wastewater plants. Pricing is quote-based rather than published. Go-to-market is enterprise field sales executed through regional offices in Austria (Vienna HQ, Ternitz production), Czech Republic (Prague), Romania (Bucharest and Sibiu production), and Hungary (Budaörs), backed by a partner network of 23+ pump manufacturers and exclusive regional representation for HARTER and DORSET sludge technologies. The company has delivered referenced projects in oil & gas (Pakistan Zamzama, Kazakhstan Tasbulat, Gabon Remboue, Austria Gänserndorf) and railway (ÖBB toilet systems, 2005-2020).

Sonnek serves seven primary customer verticals — oil & gas exploration/refining, food & beverage, wastewater treatment, pharmaceutical & cosmetics, chemical & petrochemical, railway, and fire protection — using a vertical segmentation approach. Manufacturing is anchored in Ternitz (Austria), which received EU EFRE funding for a new Plug & Pump production hall inaugurated in 2024, and Sibiu (Romania), with reported headcount of more than 180 employees and an operational footprint spanning more than 50 countries. CEO Werner Wieseneder leads the firm, which maintains subsidiaries including VANA (food processing) and SWS Engineering & Consulting in Romania.
