📄 Product Description

This used Dorr-Oliver H-30 Merco Nozzle Centrifuge is a high-capacity, continuous solids separation unit designed for robust industrial performance. It operates at a maximum bowl speed of 3,300 RPM, with a flow rate capacity ranging between 100 to 500 GPM.

Equipped with a powerful 125 HP motor, this centrifuge provides consistent throughput in demanding applications. The 316 stainless steel bowl and wetted parts provide excellent corrosion resistance, especially suited for chemical and food-grade operations. Also included is a rotary strainer, enhancing feed pre-filtration and improving solids load control.

This model is ideal for starch recovery, bioethanol processing, protein separation, industrial slurries, and other high-throughput clarification tasks.
