1. Insufficient pump flow or pressure: a. Incorrect pump rotation—reverse the rotation b. Clogged inlet filter—clean the filter c. Impeller or wear ring wear—replace the impeller or wear ring d. Air trapped inside—ensure thorough venting

1. Insufficient pump flow or pressure:

a. Pump rotation is incorrect — change the rotation direction

b. Inlet filter clogged—clean the filter

c. Impeller or throat bushing wear — replace the impeller or throat bushing

d. Ensure that all air inside is completely vented.

2. High motor current:

a. Bearing damage—replace the bearing

b. Accumulation of impurities or material inside the pump—clean out the impurities or material completely.

c. Adjust flow rate if it is too high

3. Excessive noise and vibration:

a. Incorrect pump rotation—change the rotation direction.

b. If the coupling is misaligned, realign it according to the specified requirements.

c. The external magnetic cylinder is not properly secured to the drive shaft. Install the external magnetic cylinder in the correct position and tighten the set screw.

d. Replace the bearing if it is damaged.

e. If the base bolts are loose or pipeline-induced resonance occurs, tighten the bolts to eliminate the resonance defect.
