This stainless steel high-temperature heat transfer oil pump is designed for industrial thermal oil circulation and heating systems. It is suitable for processes that require stable heat transfer, reliable medium circulation, and simplified equipment operation.
The pump adopts a double-end ball bearing support structure. The front end is lubricated with lubricating oil, while the rear end is lubricated with grease. An oil guide pipe is installed between the bearing sections, allowing operators to observe the sealing condition and recover heat transfer oil during operation.
Instead of using a traditional water-cooling structure, this heat transfer oil pump adopts a self-cooling design. This helps simplify the pump structure, reduce overall size, and lower operating costs in supported thermal oil systems.
Features & Advantages
- Stainless Steel Construction: Designed for high-temperature heat transfer oil service where stainless steel pump construction is required.
- Double-End Ball Bearing Support: Helps improve operating stability and mechanical support during continuous circulation.
- Separate Lubrication Design: The front bearing uses oil lubrication, while the rear bearing uses grease lubrication.
- Seal Observation & Oil Recovery: The integrated oil guide pipe helps monitor sealing conditions and recover heat transfer oil.
- Self-Cooling Structure: Replaces traditional water cooling with a simplified heat dissipation design.
- Compact Equipment Layout: The simplified structure helps reduce pump size and operating complexity.

Startup & Operation Notes
Before starting the pump, all preparation work should be carefully checked. Operators should open the required instrument switches and confirm that the system is ready for operation.
During startup, the suction valve should be fully open. To prevent overload, the motor should be started only when the pump discharge valve is closed. However, the pump must not operate continuously for more than 3 minutes while the outlet pipeline valve remains closed.
After the pump reaches normal speed and the outlet pressure gauge shows the required pressure, the discharge valve should be opened and the flow adjusted to the working parameters. The suction valve must not be used to regulate pump flow, as this may cause cavitation.
During initial operation, when the medium temperature reaches 100–130°C, the pump should continue running at this temperature range. Slight vibration may occur during this dehydration stage. After dehydration is complete, the vibration should naturally disappear, and the system can then be heated to the required operating temperature.
Operators should continuously observe pump vibration during startup and operation. If abnormal vibration occurs, the pump should be stopped immediately for inspection. The pump vibration amplitude should not exceed 0.06 mm.
