Used Alfa Laval AVNX-616B-31G Stainless Steel Solid Bowl Decanter Centrifuge

Manufacturer Information

Alfa Laval is a global manufacturer of industrial separation, heat transfer, and fluid handling equipment. Its decanter centrifuges are used in continuous solid-liquid separation processes across wastewater treatment, chemical processing, food processing, and other industrial applications. These machines use centrifugal force to separate solids from liquids, with an internal screw conveyor transporting concentrated solids toward the discharge.

Main Product Description

Used Alfa Laval Model AVNX-616B-31G 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 3,250 RPM and is equipped with an 11 kW (approximately 14.8 HP) main drive motor requiring 380 volts, 3-phase, 50 Hz electrical service. The internal single-lead screw conveyor features welded hardfacing for improved wear resistance during continuous solids transport and discharge. Moon-style liquid plate dams allow adjustment of liquid pond depth and discharge conditions, while a cake vibrator mounted on the casing assists with separated solids handling. Additional features include a 2.5 kNm torque-rated gearbox, feed pipe, supporting base, and centrifuge casing. Suitable for consideration in industrial wastewater treatment, municipal sludge dewatering, biological sludge thickening, chemical slurry separation, industrial effluent clarification, food processing wastewater treatment, mineral slurry dewatering, pigment processing, and other compatible solid-liquid separation applications.
