Disc Centrifuge Liquid Seal Break or Breakover | Causes, Detection, Fixes

What is Liquid Seal Break or Breakover in Disc Centrifuges? During the normal 3-phase separation process in a disc-stack centrifuge, the heavy phase (typically water) forms a liquid seal around the periphery of the bowl. Under certain conditions, the light phase pushes out the heavy phase and escapes through the heavy phase outlet. This operating […]

Disc Stack Centrifuge Troubleshooting | Bad Separation

Synopsis Disc Centrifuge separation results depend on internal (centrifuge specific) and external (process fluid-related) factors. In this article, we discuss the common reasons behind unsatisfactory separation by disc-stack centrifuges.  We will first discuss internal, i.e., centrifuge related causes of bad separation results. Following this, we will discuss external factors that often affect separation results. Disc […]

10 Causes & Easy Fixes for Disc Stack Centrifuge Vibration

Disc stack centrifuges contain a metal bowl that rotates at a high RPM. Any rotating mass that is not correctly balanced causes vibrations. Therefore all disc stack bowls generate vibrations to varying degrees in the centrifuge under normal conditions. Under certain conditions, the disc centrifuge may vibrate more than usual, which is a cause of […]
