Used Dorr-Oliver Merco 16L Stainless Steel Solid Bowl Decanter Centrifuge

Manufacturer Information

Dorr-Oliver is an established industrial process equipment name associated with solid-liquid separation, filtration, clarification, and dewatering technologies. The Dorr-Oliver / Merco designation is associated with centrifugal separation machinery used in industrial processing applications involving suspended solids, slurries, and liquid clarification.

Main Product Description

Used Dorr-Oliver / Merco Model 16L horizontal solid bowl decanter centrifuge with 316 stainless steel product-contact surfaces, designed for continuous solid-liquid separation, slurry clarification, solids concentration, and mechanical dewatering of compatible industrial process materials. This industrial decanter centrifuge features a maximum bowl operating speed of 4,000 RPM and is driven by a 30 HP main drive motor with an ECB backdrive for differential speed control between the rotating bowl and internal screw conveyor. The machine includes a 5" double-lead internal screw conveyor with welded hardfacing for additional wear resistance during solids transport and discharge. Auger-style solids discharge and plate dam liquid discharge arrangements provide separate outlets for processed solids and liquid. Additional components include the solid bowl assembly, supporting base, discharge chutes, bowl cover, and belt guard. This Dorr-Oliver / Merco 16L centrifuge is suitable for consideration in industrial wastewater treatment, municipal and industrial sludge dewatering, chemical slurry separation, liquid clarification, starch processing, mineral slurry dewatering, pigment processing, and other compatible industrial solid-liquid separation applications.
