⚙️ Description
This Used Hiller DP 45-422 Solid Bowl Decanter Centrifuge is a robust, continuous-duty separation system engineered for sludge thickening and dewatering in municipal and industrial wastewater operations. Constructed with Alloy 2304 (EN 1.4362) duplex stainless steel on product-contact parts, the machine delivers excellent corrosion resistance and mechanical strength.
The centrifuge operates at a working bowl speed of ~3,500 RPM (with a maximum of 3,800 RPM) and features a single-lead conveyor with lined cake discharge ports and wear liners for extended service life. Driven by an approximately 30 kW (45 HP) main motor, the unit includes the frame/casing, control panel, and ancillary infrastructure, mounted on four legs for stable installation. Ideal for wastewater, biosolids, and industrial slurry separation.
