1 to prevent particles from entering (1) does not allow ferromagnetic impurities, particles into the magnetic clutch and bearing friction.

(3) In the case of the outlet valve is closed, the pump continuous operation time shall not exceed 2min, to prevent the magnetic actuator from overheating failure. 3. Not available in stressed systems 3. Prevent demagnetization (1) Magnetic moment can not be designed too small. (2) It should be run under the specified temperature, the medium temperature is strictly not allowed. A platinum resistance temperature sensor can be installed on the outer surface of the magnetic pump isolation sleeve to detect the temperature rise in the annulus area so as to alarm or stop when the temperature exceeds the limit.
