- LlramosAug 16, 2025
If your Johnson Pump Water Pump experiences no flow, it might not be primed. Ensure the pump is properly primed to resolve this issue.
What to do if my Johnson Pump Top Wing Water Pump has no flow?
If your Johnson Pump Water Pump experiences no flow, it might not be primed. Ensure the pump is properly primed to resolve this issue.
Why does my Johnson Pump Water Pump overheat?
If your Johnson Pump Water Pump overheats, it could be due to the product temperature being too high. Try reducing the product temperature.
Why does my Johnson Pump Top Wing have low capacity?
If the Johnson Pump Water Pump has low capacity, there might be gas in the suction line. Check for and eliminate any gas present in the suction line.
How to fix a Johnson Pump Water Pump that stalls on start up?
If the Johnson Pump Water Pump is stalling on start up, the direction of rotation might be incorrect. Make sure that the rotation is set correctly.
What to do if my Johnson Pump Top Wing Water Pump has irregular flow?
If your Johnson Pump Water Pump demonstrates irregular flow, it may be caused by air entering the suction line. Inspect the suction line and eliminate any air leaks.
Why is the motor of my Johnson Pump Top Wing overheating?
If the motor of your Johnson Pump Water Pump overheats, it could be because the pump speed is too low. Try increasing the pump speed.
What to do if my Johnson Pump Top Wing Water Pump experiences seizure?
If your Johnson Pump Water Pump is seizing, it might not be primed. Ensure the pump is properly primed.
Why does my Johnson Pump Water Pump have excessive rotor wear?
If your Johnson Pump Water Pump is excessively wearing the rotor, it could be because the product viscosity is too high. Reduce the product viscosity.
Why is my Johnson Pump Water Pump making noise and vibrating?
If your Johnson Pump Water Pump is producing unusual noise or vibrations, it may be due to product vaporizing in the suction line. Address the vaporization issue in the suction line.
Why does my Johnson Pump Top Wing have excessive seal wear?
If your Johnson Pump Water Pump has excessive seal wear, the discharge pressure might be too high. Reduce the discharge pressure.
