1. Insulation: Ensure that the pump and its surrounding facilities are at a suitable temperature to avoid freezing.
2. Draining or waterproofing: Pumps that are not in use should be drained of internal water, and those that are out of service for a long time should be properly waterproofed.
3. Seal inspection: Regularly check the seals to ensure they are intact and avoid leaks.
4. Operation monitoring: Ensure that the pump can still operate normally at low temperatures, monitoring flow, pressure, and other indicators.
5. Lubricating oil management: Check the condition of the lubricating oil and replace it in a timely manner.
6. Regular inspection: Regularly check the condition of the pump and address any issues promptly.

Maintenance of industrial pumps in winter is crucial to ensure safe operation and extend their service life.
