Common Centrifuge Repair Issues and How to Fix Them

Understanding Centrifuges

Centrifuges are widely used in several industries, including chemical, pharmaceuticals, food processing, and research laboratories, among others. They are commonly used for separating different materials from a liquid or a solution based on the difference in density. The basic principle behind a centrifuge’s operation is the application of a centrifugal force that can separate the materials based on their mass and density.

The Common Centrifuge Repair Issues

Although a centrifuge is an essential equipment in many industries, it is prone to some technical hitches that require repairs. Below are some of the most common repair issues:

  • Off-balance rotor
  • Excessive noise
  • Oil leaks
  • Overheating
  • Electrical faults
  • Off-balance Rotor

    An off-balance rotor is one of the most common issues that many centrifuge users face. It can occur due to a buildup of dirt, a lose rotor bolt, or improper lid closure. The solution to this problem is ensuring routine rotor maintenance, such as cleaning and proper installation, ensures the rotor is well balanced. If the off-balance issue persists, the next step is to contact a professional to provide technical help.

    Excessive Noise

    Noise is an indication that something isn’t functioning properly within the centrifuge. The source of noise can be the rotor, damaged bearings, or misaligned drive belts, among other reasons. Make sure to check for worn-out parts in the machine and replace them as soon as possible. Also, ensure to lubricate any moving parts regularly, keeping the machine clean, and aligning the drive belts correctly. If you can’t troubleshoot the problem, then contact a professional to help you with the repairs.

    Oil Leaks

    An oil leak can occur from several points in the centrifuge, including the seal, piping, and strainer. To solve a leak issue, inspect the centrifuge for any signs of wear or damage to the hydraulic lines or the seal. Replace any worn-out parts, bolt on the piping to avoid gas leak or use sealant in place of the leak seal if the issue persists, then contact an expert.


    Overheating is another common problem in centrifuges that could be caused by various reasons, including clogging, buildup, and poor ventilation. If the centrifuge gets too hot, it can damage the motor or warp the rotor. There are various remedies to overheating, including cleaning regularly and ensuring proper ventilation by leaving enough space between the equipment for air to circulate, or investing in a stronger cooling system. However, continuous overheating issues may require professional assistance.

    Electrical Issues

    In most cases, a centrifuge’s electrical issues are caused by frayed wires or a blown capacitor. If it’s a wiring problem, the machine will show signs such as the inability to turn on or off. If a capacitor is blown, the centrifuge will make a humming sound and fail to run. For minor electrical issues, a technician can swap out the wires or capacitor rather inexpensively. However, for more complex issues, contact an expert to diagnose and repair.


    Proper maintenance and troubleshooting are essential for any machinery, and your centrifuge is no exception. Always ensure your centrifuge is cleaned regularly, parts are well-oiled, and the machine is free from dirt, or debris. We hope this guide has helped provide a better understanding of the common centrifuge repair issues and how to solve them. If you cannot solve some of the issues mentioned above, it may be ideal to call an expert and avoid doing further damage to the equipment.
