However, since the pump housing and the motor of the magnetic pump are fixed by bolts, the sealing of the connection is poor, which may cause liquid leakage. In addition, the magnetic pump does not have a heat preservation function, resulting in the inability to maintain the required temperature of the liquid during the transportation process, which is quite inconvenient.
