Faults and Solutions of Magnetic Pumps

1.Can't make liquid

Reason：There is air in the suction pipe; the suction pipe is leaking
Solution: Refill liquid or exhaust gas; check suction line

2.Insufficient Flow

Reason：Impeller damaged; insufficient speed
Solution: Replace the impeller; check the motor and power supply circuit

3.Too Much Power

Reason：The proportion of the transfer medium is too large
Solution: Decrease viscosity or increase filling pressure

4.Insufficient Head

Reason：There is air in the conveying medium; the impeller is damaged; the specific gravity of the medium is too large
Solution: Refill the liquid or exhaust the air; replace the impeller; reduce the viscosity or increase the filling pressure

4.Pump Unit Vibration

Reason：The error between the pump axis and the motor axis is too large; the suction height is too large, resulting in cavitation
Solution: Re-adjust; lower installation height

5.Shaft End Leakage and Seal Leakage

Reason：The clearance of the retaining ring at the shaft end is too large, and the retaining ring is loose; the suction height is too high, resulting in cavitation
Solution: Adjust the snap ring screw to reduce the installation height

The above is about the common problems in the installation and use of the magnetic pump. If you have any other questions, please contact us. DUBAO Industry will help you solve your current problems.
