Canned pump operating procedures
Thread Content
How does the canned pump operate normally? What issues should we pay attention to?
Because the motor rotor and the impeller are connected together in the canned pump, and it uses sliding bearings and uses the transported liquid medium as the lubricant of the bearing. For this reason, the gas in the pump must be evacuated and completely filled with liquid before use. Otherwise, there will be no liquid lubrication, and the bearing will soon be destroyed. Since the matching gap between the bearing and the shaft is small, and the bearing is generally made of reinforced graphite, which is relatively brittle, this type of pump is more sensitive to vibration. If the vibration is too large, the bearing may be damaged.

The canned pump is afraid of being evacuated. Before starting, the gas phase must be released from the pipes and the pump body.
The pump exhaust must be sufficient and empty, otherwise cavitation and other phenomena will occur. Secondly, listen to the sound of the pump running and measure the temperature of the pump body. Other canned pumps are easy to maintain.
