Magnetic drive pumps can meet 90% of all application areas of sealless pumps. This pump has complete technical specifications, economical price, short delivery time, convenient use, does not require electricians to participate in maintenance, and can be directly interchanged with ordinary sealed pumps. Canned motor pumps are complex in structure and expensive, and usually cannot meet conventional standards. In addition, the sealing components involve maintenance issues, multi-work installation issues, and long delivery times, which make canned motor pumps only be used in various edge applications where magnetic pumps cannot meet the requirements and are highly dangerous. It is easy to see that although these two pumps occupy the market at the same time, the stainless steel magnetic drive pump will occupy a larger market share and become the main equipment of various environmental protection and safety industries in the future.
