the advantages of magnetic pump
When a pump operates at a lower pressure and draws higher amps, it usually means it's running further out on the curve. If this continues to a higher flow, then the motor will naturally trip out if size does not cover the run out condition of the pump. It is possible that the new impellers are larger or different hydraulic than the older ones. Unfortunately, you don't provide enough information to be absolutely certain.
Plastic magnetic pumps have many advantages
(1) shaft seal into enclosed by the moving static seal, completely avoid media leaks. Drag the drive into a synchronized by the coupling, there is no contact and friction.
(2) power consumption, high efficiency, and has a damping effect, reducing the impact of motor vibration on pumps and pump cavitation effects of vibration on the motor.
(3) No separate lubrication and cooling water, reducing energy consumption.
(4) overload, the inner and outer magnetic rotor relative slip of the motor, the pump has a protective effect.
when the Magnetic actuator driven components running in case of overload or stuck rotor, the magnetic clutch master and slave unit will automatically slip to protect the pump. At this point magnetic drive permanent magnet on the rotor in the active role of the alternating magnetic field, will generate eddy loss, magnetic loss, resulting in permanent magnet temperature, magnetic clutch slip failure.
