What is the gap between domestic pump manufacturers and foreign ones? Aspects such as design, manufacturing, efficiency, and equipment stability
It’s a good topic; looking forward to seeing results. ;P What are the advantages and disadvantages of using a vacuum pump directly to pump water, as well as using a vacuum pump in combination with water intake equipment?
