How to Troubleshoot Common Peristaltic Pump Issues

How to Troubleshoot Common Peristaltic Pump Issues

Here's a breakdown of common issues with peristaltic pumps and how to address them:

1. No Response Upon Power-On

If the peristaltic pump doesn't respond when powered on, follow these steps:

  • Check circuit protection:Ensure the circuit breaker hasn't tripped.
  • Verify power source:Confirm that the power plug is inserted into a working outlet.
  • Inspect power cord:Check if the power cord is securely connected.
  • Examine fuse:Verify that the power supply fuse is intact. If the issue persists, consult the manufacturer.

2. Pump Powers On but Doesn't Operate

Inspect the coupling for damage. If it's undamaged, turn off the power, manually rotate the pump head, and try moving the rollers. If they don't move freely, there might be an issue.

3. Low or No Flow

First, ensure that the flow rate setting is not too low. For example, a setting of 0.1ml might result in minimal roller movement. Test with a higher setting. Additionally, check the following:

  • Supply:Verify that the supply is functioning correctly.
  • Tubing:Check for kinks or blockages in the tubing.
  • Valves: Ensure all valves are open.  
  • Tubing position:Confirm that the tubing is centered on the rollers.
  • Tubing condition:Inspect the tubing for cracks or damage.
  • Direction:Verify that the pump is running in the correct direction.
  • Rotor:Check if the pump head rotor can rotate freely.

4. External Control Issues

Regardless of whether you have a digital or LCD display, check if the external control icon is displayed. If it is, verify that the external control cable is correctly connected and that the signal source is configured appropriately.
