Excessive sludge can potentially clog the bowl discs in a disc stack centrifuge. If the sludge enters the inter-disc space, it blocks the passage for fluid to pass between discs. This condition is known as a clogged disc stack, drastically affecting the centrifuge performance. Clogged bowl discs can also be a safety issue and should… Continue reading Disc Stack Centrifuge Troubleshooting | Clogged Bowl Discs

10 Reasons a Disc Centrifuge Cannot Reach Operating Speed
A disc stack centrifuge uses the centrifugal force it generates to separate the liquid from solid and liquid from liquid. The centrifugal force exerted is a direct function of the bowl’s rotating speed. A disc centrifuge cannot reach operating speed due to several reasons. In this article, we will explore the causes and relevant fixes… Continue reading 10 Reasons a Disc Centrifuge Cannot Reach Operating Speed
Disc Centrifuge Friction Clutch Maintenance: A complete guide
If you have an Alfa Laval disc stack centrifuge, it is crucial to know how to maintain the friction clutch to avoid centrifuge breakdowns and unplanned maintenance downtime. Also, a worn-out clutch causes a host of other issues for the centrifuge in the long run. This article discusses the maintenance and repair of the friction… Continue reading Disc Centrifuge Friction Clutch Maintenance: A complete guide
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… Continue reading Disc Centrifuge Liquid Seal Break or Breakover | Causes, Detection, Fixes
Disc Stack Centrifuge Troubleshooting | Paring Disc Block
Synopsis The paring disc (aka impeller) is the centripetal pump built into the disc stack centrifuge bowl. The dense phase (often water) paring disc gets blocked with solids (plugged) in high sludge applications. This article discusses the cause of this problem and possible solutions for Alfa Laval and similar disc-stack centrifuges. Water Paring Disc –… Continue reading Disc Stack Centrifuge Troubleshooting | Paring Disc Block
Disc Stack Centrifuge Troubleshooting | Bowl Leaking
Synopsis Disc stack centrifuge bowl leaking is a common occurrence. This troubleshooting article will discuss the various reasons for the bowl leaking and how to fix it. This article refers to some disc-stack centrifuge bowl parts which are unique to these types of machines. The reader can see a brief explanation of each of these… Continue reading Disc Stack Centrifuge Troubleshooting | Bowl Leaking
Disc Stack Centrifuge Troubleshooting | Bowl Opening / Closing
Synopsis A self-cleaning disc stack centrifuge ‘cleans’ itself by ejecting the separated sludge from the bowl. The centrifuge bowl has to ‘open’ and ‘close’ to facilitate this ejection step. Therefore, the opening and closing of the bowl are critical steps in the disc centrifuge operation. A bowl not opening or not closing is a common… Continue reading Disc Stack Centrifuge Troubleshooting | Bowl Opening / Closing
