Axial-seal-free magnetic pumps are used to transport corrosive, flammable, explosive, and toxic chemical fluids; the safety, reliability, and service life of such chemical pumps are of great importance. If magnetic pump issues arise due to improper design or configuration, it will cause numerous problems and negative effects for the user, with both direct and indirect costs being difficult to estimate. Magnetic pump boasts excellent properties such as corrosion resistance, high strength, light weight, and a long service life. In recent years, magnetic pumps have been widely used in industries such as shipbuilding and rail vehicles. With the development of the machinery manufacturing sector, magnetic pumps are expected to have even broader application prospects. Due to its corrosion resistance, high-temperature tolerance, and wear resistance, stainless steel will play an even more active role in China’s key industries such as energy, petrochemicals, power generation, and mining. Today, magnetic pump applications are expanding into an increasing number of fields, with demand in the water treatment industry, construction and structural industries, environmental protection sector, and industrial facilities also rising year by year. 1. The structural design of shaftless magnetic pump: As a type of magnetic pump used for transporting chemical substances, when designing such a pump, the key factors to consider first are its reliability, safety, and service life. These key factors relate to whether a pump can operate for extended periods without or with minimal maintenance, as well as the costs associated with consumption and spare parts for the user, along with intangible aspects such as environmental and safety issues. Therefore, it is necessary to design and manufacture a magnetic pump that can maintain the stability of the dimensions of its various components under different temperature, pressure, and load conditions, thereby ensuring fault-free operation of the pump over the long term. This is the mindset and philosophy that a product designer should have. It is not appropriate to reduce the weight and quality of the products in order to cut down production costs, and to deliver magnetic pumps with low costs and low prices to end-users. 2. The arrangement of the friction components in magnetic pump systems: For chemical pumps, the vulnerable parts are those that are constantly in contact with and subject to friction within the liquid, such as sliding bearings, thrust bearings, and shaft sleeves. The wear resistance of these components directly affects the pump’s service life as well as the cost for users to replace them. Where corrosive conditions permit, tungsten carbide material with good bending strength and impact resistance can be chosen. Tungsten carbide has advantages over silicon carbide, such as better toughness and impact resistance. In the event of dry grinding of the pump, it will not break like silicon carbide does, which could lead to friction between the internal magnetic steel and components such as the isolation sleeve, thereby causing damage to the pump. The highest-grade configuration for the wear-prone parts of magnetic pumps uses silicon carbide and tungsten carbide, which enables the pump to operate for extended periods without requiring maintenance. Its service life is much longer than that of materials such as PTFE graphite, graphite, alumina, and silicon nitride. It can reduce the costs associated with the frequent replacement of wear-prone parts and other components over a short period of time, due to factors such as their poor wear resistance and low strength, as well as costs related to the environment and safety.
