Product Description
The Alfa Laval DSNX 4555 Solid Bowl Decanter Centrifuge is a durable, industrial-grade separation system designed for continuous solid-liquid separation in demanding environments. Constructed with 316 stainless steel in all product contact areas, this unit offers excellent corrosion resistance and long-term reliability, particularly in wastewater and chemical processing applications.
With a maximum bowl speed of 3250 rpm and a 20-degree bowl angle, the centrifuge delivers efficient phase separation and high solids capture. The system features a single lead conveyor, lined cake discharge ports, and moon-type liquid plate dams to optimize separation performance and throughput.
Powered by a 55 kW ABB main drive motor and equipped with a 6 KNM gearbox, this decanter is built for heavy-duty industrial use. The unit is mounted on four legs and includes a control panel for operational management. Previously used in a wastewater treatment setting, this centrifuge remains a dependable solution for dewatering and clarification processes.
