High-temperature oil pumps are positive displacement pumps that transfer media by utilizing the working volume change caused by the engagement of the main and driven gears. This design allows high-temperature oil pumps to operate stably in high-temperature environments while ensuring efficient transfer.

4. Application Fields: High-temperature oil pumps are widely used in industries such as petroleum, chemicals, metallurgy, plastics, rubber, pharmaceuticals, food, and energy. They are particularly suitable for systems requiring high-temperature heating and circulating mediums, such as high-power mold temperature machines, pipeline boosting, boiler return water systems, woodworking machinery, and wind energy technology auxiliary heating equipment.
