Fristam pumps are relatively maintenance free; however, in the event that a problem arises, the following
troubleshooting chart will help you with most of your pump-related problems. If a motor or drive problem
arises, please contact your local motor repair representative.
This troubleshooting chart has been prepared assuming the installed pump is suitable for the applica-
tion. If you have questions about your application please contact your local pump distributor to check
the system and re-evaluate the application or contact Fristam Pumps, Inc. at 1-800-841-5001 or 608-
831-5001.
