How to conduct regular inspections of stainless steel multi-stage pumps

Stainless steel multi-stage pumps require regular inspection to avoid affecting their performance. What is the regular inspection of stainless steel multi-stage pumps?
1. Daily inspection, i.e. in use inspection, as described above.
2. Monthly inspection, cleaning and minor repairs of the equipment surface without dismantling components, including inspection of bearing temperature, causes of shaft seal leakage, and motor insulation.
3. Regular maintenance includes replacing the lubricating oil of the shaft seal, checking the alignment of the centrifugal pump and motor, checking the wear of the shaft sleeve, checking the damage of the coupling rubber ring, cleaning the mechanical seal, coolant filter, and pump filter, checking the wear of sliding components, and checking the damage and corrosion of various components in contact with the liquid body.
