Used Dorr-Oliver Merco 16L Stainless Steel Decanter Centrifuge – 30 HP

Manufacturer Information

Dorr-Oliver is an established name in industrial separation and processing equipment, including centrifuges, filtration systems, and solid-liquid separation machinery. The Dorr-Oliver / Merco name is associated with industrial centrifugal separation equipment used in applications involving slurry processing, solids concentration, liquid clarification, and mechanical dewatering.

Main Product Description

Used Dorr-Oliver / Merco Model 16L horizontal solid bowl decanter centrifuge with 316 stainless steel product-contact construction, designed for continuous solid-liquid separation, slurry clarification, solids concentration, and mechanical dewatering of compatible industrial process materials. This decanter centrifuge features a 30 HP main drive motor, maximum bowl operating speed of 4,000 RPM, and an ECB backdrive for controlling differential speed between the rotating bowl and internal screw conveyor. The unit includes a 5" double-lead screw conveyor with welded hardfacing for increased wear resistance during solids transport and discharge. Auger-style solids discharge ports support separated solids removal, while plate dam liquid discharge provides a dedicated liquid outlet arrangement. Additional components include a supporting base, discharge chutes, bowl cover, and belt guard. Suitable for consideration in industrial wastewater treatment, municipal sludge dewatering, chemical slurry separation, industrial sludge thickening, mineral slurry processing, starch and food processing waste separation, and other compatible solid-liquid separation applications.
