Product Introduction The Series is the industry-standard centrifugal pump for high-temperature heat transfer systems. It is a proven and highly reliable solution, engineered for the demanding task of continuously circulating thermal oil and other heat transfer fluids. Its design is centered on a robust and effective air-cooling system that protects the pump’s critical components from extreme heat, ensuring a long and trouble-free service life. The pump is the trusted choice for countless industrial heating processes that depend on consistent and reliable performance.
Design Philosophy & Construction The pump is purpose-built for durability and longevity in continuous, high-temperature service.
- Advanced Air-Cooling Structure: The pump is designed with an extended distance piece between the hot pump casing and the bearing housing. This intermediate section is cast with large, deep cooling fins that maximize the surface area exposed to the air. This design allows heat to naturally radiate away from the shaft, seal, and bearings.
- Forced Convection Cooling: To enhance the cooling effect, many models incorporate a shaft-mounted fan. As the pump operates, this fan actively pulls ambient air across the cooling fins, creating a forced-air cooling system that is more effective than natural convection alone. This ensures the seal and bearings remain at a stable, safe operating temperature.
- High-Temperature Seal and Bearings: The pump is fitted with a specialized mechanical seal and heavy-duty ball bearings selected specifically for hot oil service. These components are designed to handle extreme temperatures and the low viscosity of thermal fluids, providing reliable sealing and support.
Key Features & Benefits
- Proven Industry Reliability: The pump design is a well-established and trusted solution with a long track record of reliable performance in heat transfer applications.
- Effective Air-Cooling: The finned structure, often enhanced with a cooling fan, provides excellent heat dissipation without the cost and complexity of external water cooling.
- Built for Continuous 24/7 Operation: The heavy-duty, long-coupled construction is designed to withstand the thermal and mechanical stresses of non-stop industrial heating processes.
- Enhanced Safety: By keeping the seal and bearings cool, the design minimizes the risk of seal failure, which is a primary safety concern when pumping hot, flammable oil.
- Low Maintenance Requirements: The simple, robust design with no required external utilities (like cooling water) results in a low-maintenance, “set-and-forget” operational experience.
Common Applications The pump is the workhorse for a vast range of industrial process heating tasks:
- Primary Circulation in Thermal Oil Heaters: Circulating heat transfer fluid from the main heater to the entire plant.
- Manufacturing Processes: Supplying process heat in the plastics, rubber, chemical, and textile industries.
- Food Production: Circulating hot edible oils for industrial ovens and deep fryers.
- Wood and Paper Mills: Providing heat for presses, dryers, and calendering rolls.
- Asphalt Plants and Roofing Material Production: Pumping hot bitumen, asphalt, and other high-viscosity materials.
