Product Highlight
Düchting WRX W 150-660 HD
Diesel Skid Dewatering Pump Unit
High-head, high-volume mine dewatering — engineered in Germany, stocked in Indonesia
The WRX W 150-660 HD is a heavy-duty single-stage horizontal centrifugal pump, built by Düchting Pumpen in Hagen, Germany, and delivered as a turn-key diesel skid for open-pit mine dewatering by PT ODG, Düchting’s authorised distributor in Indonesia.
The unit is engineered as a direct bolt-on alternative for existing 400-class diesel-skid installations — same operating envelope, same footprint, in- country wet-end stock, and a 30–50% lifecycle cost advantage on abrasive coal-water and acidic process-water duties. Suited to coal, nickel laterite, copper-gold, quarrying, water transfer and emergency dewatering applications across Kalimantan, Sulawesi, Sumatra, Maluku and Nusa Tenggara.
