What Hidrostal Process Engineering does

Hidrostal Process Engineering AG is the Swiss engineering, consulting, and sales entity of the privately held, family-owned Hidrostal Group, headquartered in Urdorf, Switzerland and organized under Hidrostal Holding AG in Neunkirch. The company designs, manufactures, and services pumps based on its proprietary screw centrifugal (Schraubenzentrifugalpumpe) impeller technology, originally invented by founder Martin Stähle in 1957. The group operates three production facilities (Switzerland, China, Hungary) plus a Polish foundry, and serves customers in over 100 countries through approximately 20 wholly-owned subsidiaries providing direct sales, engineering, service, and rental.

The core product portfolio spans eight pump configurations (End Suction Volute, Compact, Submersible, Immersible, Bearing Frame, Axial Diffuser, Axial Column, Vertical Turbine), all built on the single-vane screw centrifugal impeller, with 800 standard hydraulics combinable with roughly 40 motors or 40 bearing frames. Adjacent systems include SuperBetsy mobile self-priming pump units, PreroClean and Prerostal self-cleaning pump sumps, HidroMix mixing systems, and Floating Pump Systems. Digital offerings include the HidroSelect configuration tool and the HidroSmart/HidroScope cloud monitoring platform offered on tiered multi-year subscriptions. The company generates revenue across five streams: pump and system sales, service and repair (including 24/7 support), rental, spare parts, and recurring digital subscriptions, delivered primarily through enterprise field sales with technical consulting.

Hidrostal targets municipal wastewater authorities as its primary segment, with secondary exposure to construction, food and beverage, pulp and paper, mining, marine/offshore, and oil and gas. Differentiation rests on the original screw centrifugal patent portfolio, the highest Free Passage Index in market for clog-free operation, pump efficiency up to 87%, vertical foundry integration, and a global subsidiary network providing local service. The company has remained self-financed since founding, completing targeted bolt-on acquisitions such as Bedford Pumps (UK, 2001), HidroCast (Poland, 2017), and Avonmouth Engineering Services (UK, 2020), and is currently led by CEO Rolf Schweizer (since spring 2022) and Chairman Dr. Daniel Häring (since summer 2022).
