In many critical industrial processes, the ability to move heat transfer fluids safely and reliably is a core requirement. This is where high temperature oil pumpsplay a vital role — designed to operate under extreme thermal conditions while maintaining consistent pressure and flow. From thermal oil systems in chemical plants to hot oil circulation in textile machinery, these pumps are central to the efficiency and safety of countless operations.

One company that has been meeting this high-performance demand with confidence is Shanghai Lanhai Pumps, a trusted manufacturer known for engineering durable, thermally resilient pumping solutions tailored to complex industrial environments.

Where High Temperature Oil Pumps Matter Most

Unlike standard oil pumps, high temperature variants are specially built to handle thermal transfer fluids like synthetic oils or mineral-based heat transfer mediums at temperatures ranging from 150°C to over 350°C. These pumps are engineered to resist heat distortion, prevent seal failure, and minimize thermal expansion — all while delivering precise, uninterrupted circulation.

Here are key industries that rely on high temperature oil pumps:

1. Chemical and Petrochemical Processing
Reactors and distillation units often require precise temperature control through thermal fluid heating. High temperature oil pumps are responsible for circulating heat transfer oils within jacketed vessels, maintaining thermal stability even in continuous 24/7 operations.

2. Plastics and Rubber Manufacturing
Processes such as injection molding, extrusion, and calendaring depend on hot oil systems to ensure mold and roller temperature stability. Pumps must withstand rapid temperature fluctuations and provide smooth flow to avoid quality defects in the final products.

3. Food and Beverage Industry
In applications like frying, baking, or high-temperature sterilization, thermal oil circuits provide indirect heating. Here, high temperature oil pumps ensure food-safe operations by preventing hot spots, oil degradation, or flow interruptions.

4. Textile and Dyeing Plants
Machines like stenter frames or heat-setting dryers use thermal oil for consistent heating. Pumps in this environment must deliver high reliability, as downtime can significantly impact production schedules and quality.
