Manufacturer Information

Alfa Laval

Alfa Laval manufactures industrial separation, heat-transfer, and fluid-handling equipment for food, beverage, chemical, wastewater, environmental, and other processing industries. Its solid-bowl decanter centrifuges are designed for continuous separation of suspended solids from compatible liquid process streams.

This Alfa Laval NX-418 features 316 stainless steel product-contact areas, a maximum bowl speed of 4,000 RPM, and a gearbox with back drive.

Description

Available for sale is a used Alfa Laval NX-418 solid bowl decanter centrifuge designed for continuous centrifugal separation of compatible liquid/solid mixtures.

Product-contact areas are constructed of 316 stainless steel. The centrifuge has a stated maximum bowl speed of 4,000 RPM and features 110 mm spacing between the scroll flights.

The solids discharge configuration includes a double row of lined cake discharge ports, which provides wear protection at a high-abrasion area of the centrifuge. The liquid discharge incorporates moon-style liquid plate dams.

A gearbox with back drive is included for controlling the differential relationship between the bowl and internal scroll. The complete centrifuge is mounted on a support frame with legs.

This NX-418 may be considered for compatible applications involving dewatering, clarification, solids recovery, sludge thickening, and continuous liquid/solid separation.
