In the fields of chemical engineering, medicine, and environmental protection, stainless steel self-priming magnetic pumps, as a new generation of leak-proof transportation equipment, have gradually become the preferred choice for enterprises due to their unique design and excellent performance.

Working Principle of Stainless Steel Self-priming Magnetic Pumps

The stainless steel self-priming magnetic pump replaces the traditional mechanical shaft seal with magnetic coupling transmission. The motor rotor and the impeller have no direct contact, avoiding the risk of medium leakage. The pump body is internally designed with a self-priming chamber, which can be filled with a certain amount of liquid before startup, and then uses the principle of gas-liquid mixture in the pump chamber to achieve automatic liquid intake without the need to install a bottom valve.

Main Advantages

Strong leak-proof performance: The magnetic drive design without shaft seals has completely solved the leakage problem in the transportation of chemical liquids.

Excellent corrosion resistance: Made of 304 or 316L stainless steel, it can withstand most acids, bases and organic solvents.

Self-priming capability is strong: Suitable for low liquid level conditions, simplifying the pipeline layout.

Low maintenance cost: Compact structure, no need to frequently replace seals, extends service life.

Application Fields

Chemical raw material transportation

Pharmaceutical industry solution transfer

Wastewater treatment and environmental protection projects

Fine chemicals and laboratory fluid transportation

Thanks to its safety, stability and economy, stainless steel self-priming magnetic pumps are gradually replacing traditional centrifugal pumps and becoming the ideal choice for leak-proof conditions.
