Bucher Unipektin AG

Bucher Unipektin AG, headquartered in Niederweningen, Switzerland, is an industrial machinery manufacturer and part of the Bucher Industries group, serving the food, beverage, and environmental sectors. The company designs, builds, and commissions machines and complete processing lines — from customer consultation through basic engineering, plant construction, assembly, installation, and commissioning — with a global presence through seven subsidiaries spanning Switzerland, Poland, China, Czech Republic, Germany, Spain, and New Zealand. In the environmental sector, Bucher Unipektin focuses on sludge dewatering for municipal wastewater, industrial effluent, drinking water treatment, and textile industry filtration. Their core product line is the Bucher HPS (Hydraulic Press System) series of filter presses, which use a rotating cylinder-piston system with hydraulic drive to achieve high dry-solid content from sludge with 2–10% incoming solids. The HPS range includes four models — the HPS 3007, HPS 6007, HPS 7507, and HPS 12007 — offering throughputs from 100 to 800 kg dry residue per hour and filter areas from 18 to 82 m². The cyclic pressing process (70–120 minutes per cycle) repeatedly compresses and loosens the filter cake to maximize dewatering, and the system operates continuously without supervision. Beyond dewatering, Bucher Unipektin provides solid-liquid separation, grinding technology, adsorption and ion-exchange systems (via Bucher Alimentech in New Zealand), vacuum and freeze drying (lyophilization), brewing solutions (via Bucher Denwel), and citrus juice extraction (via Bucher Exzel). The company also operates test centers for process development and offers myBucherUnipektin customer portal and NetServicePlus remote machine access.
