## 2.1 Material Selection

The high-temperature resistant performance of high-temperature magnetic pumps mainly relies on material selection. Generally, high-temperature magnetic pumps are manufactured from high-temperature resistant and corrosion-resistant materials including stainless steel, alloy steel and ceramics. These materials feature excellent thermal resistance and can maintain stable operation under high-temperature environments.

## 2.2 Design Features

The design of high-temperature magnetic pumps fully meets high-temperature resistance requirements. Firstly, an integrated structure is adopted for the pump casing and impeller to prevent leakage at joints caused by thermal expansion under high temperatures. Secondly, high-temperature resistant grease is used for bearings to mitigate the adverse impacts of high temperature on bearings. In addition, a special cooling system is equipped inside the pump chamber to effectively lower the temperature of the pump casing.

## 3.1 High-Temperature Resistant Materials

The selected high-temperature resistant materials for magnetic pumps possess high strength, high toughness and high wear resistance, enabling the pumps to resist deformation and aging in high-temperature environments.

## 3.2 Thermal Stability

Thermal stability is fully considered during the design and manufacturing of high-temperature magnetic pumps. For instance, the monolithic pump casing prevents leakage at connecting parts resulting from thermal expansion under high temperatures; high-temperature resistant bearing grease reduces high-temperature damage to bearings.

## 3.3 Corrosion Resistance

Materials adopted for high-temperature magnetic pumps have outstanding corrosion resistance, which effectively protects the pump casing from corrosion by high-temperature media and extends the service life of the pump.

## 3.4 Optimized Design

The design of high-temperature magnetic pumps fully follows hydrodynamic principles. During high-speed rotation, stable pressure is maintained inside the pump chamber, reducing deformation and aging triggered by pressure fluctuations.
