Thermal Oil Circulation Hot Oil Pumps

The first generation of magnetic pump in China was born here. After nearly 40 years of continuousimprovement and upgrading, Tengyu brand magnetic pump has won high praise from domestic and foreign customers. We have always been committed to providing customers with safer, more reliable and more efficient products.
CQ magnetic drive pump is a seal-less centrifugal pump. It is the best selling and most popular product in Tengyu. CQ pump is very cost effective, easy to use and maintain. It has relatively simple structure, so it is very easy to repair or change wearing parts. There are various stainless steel type(321, 304, 316, 316L) can be chosen according to the different medium.

Product Features

1.  Adopt a world-class hydraulic model, optimized for thermal oil characteristics, reducing energy consumption by 20%-30% compared to competitors, aligning with energy-saving standards.

2.  Use high-energy rare earth permanent magnetic materials, ensuring stable magnetic torque even at 350℃, with transmission efficiency over 96% to avoid operational interruptions.

3.  Innovate low-eddy-current insulation sleeves made of high-temperature PPS composite material, cutting eddy current loss by 40% and preventing thermal oil leakage.

4.  Equip a dedicated high-temperature lubrication cooling system and automatic axial force balance mechanism, controlling pump temperature and extending service life by 35%+.

5.  Sliding bearings feature SiC-high-temperature alloy composite with advanced hydrodynamic lubrication, service life exceeding 12,000 hours, reducing maintenance needs.

6.  Intelligent dual-protection for liquid break and overload, cutting power within 0.2 seconds to avoid dry grinding and motor burnout.

7.  High-temperature and pressure resistance: -20℃ to 350℃ operating temperature, 2.5MPa maximum pressure, compatible with multiple thermal oil types.


Application Advantages

1.  Wide applicability: Suitable for thermal oil circulation systems in industries such as chemical, pharmaceutical, rubber, plastic, printing and dyeing, and food processing. It can be used for heating, cooling, and heat transfer processes, meeting diverse industrial temperature control needs.

2.  Stable temperature control: The high-efficiency hydraulic design and stable transmission performance ensure uniform flow and pressure of thermal oil, avoiding temperature fluctuations in production equipment. This improves product quality and production process stability.

3.  Low maintenance cost: The modular structure design, wear-resistant components, and intelligent protection system reduce failure rates and maintenance frequency. Daily maintenance only requires regular inspection of lubricants and filters, saving time and labor costs for enterprises.

4.  Environmental protection and safety: The seal-less magnetic drive design eliminates thermal oil leakage, avoiding environmental pollution and safety accidents such as fires. It complies with international environmental protection and safety standards, helping enterprises achieve green production.


FAQ

1. What temperature range can Thermal Oil Circulation Hot Oil Pumps handle?

These pumps are designed to operate reliably at continuous temperatures up to 350–400°C, depending on the selected model and system configuration.

2. How does the magnetic-drive structure improve safety?

The magnetic-drive eliminates mechanical seals, preventing leakage of thermal oil and ensuring stable, contamination-free, and maintenance-friendly operation.

3. What industries commonly use Thermal Oil Circulation Hot Oil Pumps?

They are widely used in chemical plants, petrochemical systems, textile mills, food processing, pharmaceutical heating, and industrial energy-saving heat transfer systems.

4. How do these pumps prevent damage during dry-running?

The built-in liquid break protection and overload shutdown system automatically stop the pump when abnormal conditions are detected, protecting internal components.

5. What are the maintenance requirements for this pump?

Thanks to a non-contact magnetic drive and hydrodynamic bearings, maintenance is minimal. Routine inspection of lubrication flow and temperature is typically sufficient.
