Why the magnetic pump is strictly prohibited idling

Magnetic pumps, as a special type of liquid transfer equipment, have operating specifications that are critical to equipment life and safety. This article will delve into why magnetic pumps need to avoid idling when in operation, revealing the reasons and implications.

Principle of operation

Magnetic pumps achieve liquid transfer by means of a magnetic drive, the key part of which consists of an external drive mechanism with an internal magnetic coupler. This design ensures that the pump operates without leakage.

Hazards of Idle Running: High Temperature Damage: In the absence of liquid cooling, the inside of a magnetic pump may heat up rapidly due to high speed rotation, causing critical components to exceed their temperature limits and damaging the equipment.

Bearing wear: idling will cause the pump bearing to run without liquid lubrication, accelerating bearing wear, reducing equipment life.

Magnetic transfer problems: Magnetic pumps without liquid conditions, the magnetic transfer between the inner and outer magnetic couplings may be unstable, affecting the normal operation of the pump.

Safety Recommendations: Starting under liquid conditions:Before starting the magnetic pump, make sure there is enough liquid in the pump to provide cooling and lubrication. Prevent prolonged idling:Avoid prolonged idling to prevent equipment damage due to increased temperatures.

Regularly check the fluid supply:Regularly check the fluid supply for proper functioning to ensure that the pump is always operating in proper working condition.

Strictly prohibiting idling of the magnetic pump is to ensure the stability, reliability and safety of the equipment. Operators should operate the magnetic pump reasonably in strict accordance with the instruction manual and safety regulations to maintain the normal operation and prolong the service life of the equipment.
