Causes of a Peristaltic Pump Motor Not Rotating

There are several possible reasons why a peristaltic pump motor may not rotate, including damaged pump head rollers, clogged tubing, worn profile components, or motor failure. Timely identification and resolution of these issues is crucial to ensure normal equipment operation. Some common causes are:

Damaged Pump Head Rollers

Cause: During prolonged use, the pump head rollers may become damaged due to mechanical wear or accidental impact, preventing the motor from operating properly.

Solution: Check the condition of the pump head rollers. If damage or jamming is detected, it is recommended to replace the rollers immediately to restore normal pump function.

Clogged Tubing

Cause: If the medium is too viscous or contains particles, or if foreign objects are present in the tubing, blockages can occur, causing the motor to stop.

Solution: Inspect the tubing, remove any blockages, and ensure smooth fluid flow. Regular cleaning and timely replacement of hoses can help prevent this issue.

Worn Profile Components

Cause: Over time, the internal rubber profile components of the peristaltic pump may wear down, reducing pump efficiency or even stopping the motor.

Solution: Check the wear of the profile components. Replace worn rubber profiles as needed to ensure normal pump operation.

Motor Malfunction

Cause: Motor aging, poor electrical connections, or internal circuit issues can lead to motor failure and prevent rotation.

Solution: First, check all electrical connections to ensure they are secure. If the problem persists, replace the motor or contact a professional technician for further inspection.
