Fristam pumps are relatively maintenance free, however, in the event that a problem does arise, the
troubleshooting chart below should help you with most of your pump related problems. If a motor
problem arises please contact your local motor repair representative.
This troubleshooting chart has been prepared assuming that the pump installed is suitable for the ap-
plication. Symptoms of cavitation can result when a pump is not properly applied. Examples of these
symptoms are noisy operation, insufficient discharge, and vibration. If these conditions are present,
check the system and re-evaluate the application. If you need assistance, contact Fristam Pumps at
1-800-841-5001 or 608-831-5001.
