Troubleshooting Guides
Browse our complete library of 14 centrifuge troubleshooting articles. Each guide is based on real-world repair experience from the Dolphin Centrifuge knowledge center, covering both disc stack centrifuges and decanter centrifuges.
Top 10 Mechanical Issues & Fixes
The most common mechanical problems found in disc stack centrifuges and their proven solutions — from bearing failures to seal leaks.
Cannot Reach Operating Speed
Diagnose why your disc centrifuge won't reach full RPM. Covers motor issues, clutch slip, bowl imbalance, and drive system faults.
Troubleshooting Bowl Leaking
Step-by-step guide to diagnosing and fixing bowl leaks — from worn O-rings and gaskets to hood/bottom cracks and spindle issues.
Bad Separation — 6 Common Causes
Why your centrifuge isn't separating properly. Six root causes including wrong gravity disc, temperature issues, and throughput problems.
Disc Stack Centrifuge Vibration
Causes and solutions for excessive vibration in disc stack centrifuges — bowl imbalance, bearing wear, foundation problems, and more.
Decanter Centrifuge Vibration
Troubleshoot vibration issues specific to decanter centrifuges — scroll wear, differential speed problems, and feed inconsistencies.
Clogged Bowl & Discs
How to prevent and fix clogged bowls and disc stacks. Covers sludge buildup, improper discharge timing, and cleaning procedures.
Liquid Seal Break
Understanding and preventing liquid seal breaks — causes include wrong gravity disc size, air ingestion, and operating water failure.
Paring Disc Block
Diagnose paring disc blockages that cause high backpressure, reduced throughput, and poor discharge quality.
Backpressure Guide
Understanding centrifuge backpressure — how it affects separation, proper measurement, and adjustment techniques.
Friction Clutch Problems
Diagnose friction clutch issues including slipping, overheating, and premature wear. Covers adjustment and replacement procedures.
Product Loss During Discharge
Why valuable product is lost during bowl discharge and how to minimize it through timing, water settings, and operating adjustments.
Troubleshoot Bowl Issues
Comprehensive guide to diagnosing disc centrifuge bowl problems — from assembly errors to worn components and cracked parts.

Frequently Asked Questions
+ What are the most common disc stack centrifuge problems?
The most common disc stack centrifuge problems are: (1) excessive vibration from bowl imbalance or bearing wear, (2) bad separation from wrong gravity disc, low temperature, or clogged discs, (3) cannot reach operating speed from motor, clutch, or drive problems, (4) bowl or hood leaking from worn O-rings or cracked components, and (5) liquid seal break from operating water failure or wrong gravity disc size.
+ Why is my disc stack centrifuge vibrating excessively?
Excessive vibration in a disc stack centrifuge typically indicates bowl imbalance, worn spindle bearings, an improperly assembled bowl after service, or foundation problems. Other causes include a solids-overloaded bowl that was not discharged properly, a cracked disc, or contamination between disc stack components. Our vibration troubleshooting guide covers each cause with a step-by-step diagnostic procedure.
+ Why is my centrifuge producing poor separation quality?
Poor separation is most often caused by: incorrect gravity disc size (wrong interface position), feed temperature too low (high viscosity), excessive feed rate, clogged disc stack, worn paring disc, or wrong centrifuge type for the application. Our bad separation guide covers 6 root causes with corrective actions for each.
+ What causes a liquid seal break in a disc stack centrifuge?
A liquid seal break occurs when the oil/water interface inside the bowl collapses, allowing one phase to contaminate the other outlet. Causes include: operating water pressure failure, wrong gravity disc size, air ingestion into the feed, sudden feed composition change, or excessive feed rate that overwhelms the interface. Our liquid seal break guide covers diagnosis and recovery procedures.
+ Does Dolphin Centrifuge offer live centrifuge troubleshooting support?
Yes. Dolphin Centrifuge provides free lifetime technical support to all customers. Call (248) 522-2573 or email sales@dolphincentrifuge.com for immediate troubleshooting assistance. Our engineers can diagnose most disc stack and decanter centrifuge problems by phone with detailed description of symptoms, operating conditions, and recent maintenance history.
