Multistage Pumps Explained: Types, Applications, and How They Work
May 11, 2025
Hot oil pumps become indispensable in an era where hot oil systems power heavy-duty processes, ranging from chemical processing to food manufacturing. These heavy-duty mechanical wonders are designed to handle high-temperature fluids, as high as 300°C and above, without compromising performance or safety. As industries become more energy efficient and process-focused, the call for precision-crafted, reliable, and thermal-resistant hot oil pumps is climbing.
As an emerging hotspot of industrial innovation, India harbours some of the world’s most renowned hot oil pump manufacturers. In this blog post, we look at the top manufacturers in 2025, the varieties of pumps on offer, and how to decide when procuring a high-performance pump.
What Are Hot Oil Pumps?
Hot oil pumps are centrifugal or positive displacement pumps designed to transport thermal oils (heat transfer fluids) used in closed-loop heating systems. These systems are prevalent in:
- Chemical plants
- Plastic and rubber processing
- Oil refineries
- Pharmaceutical industries
- Food and beverage production units
The challenge lies not merely in withstanding extreme temperatures but with unwavering operational integrity and safety.

Important Points for Choosing the Correct Hot Oil Pump
Your system’s safety, efficiency, and longevity depend on selecting the correct pump. Keep the following points in mind:
- Operational Temperature: Ensure the pump is designed to handle constant exposure to hot fluids at 250–350°C.
- Fluid Viscosity: Heavy-viscosity fluids require positive displacement pumps; thinner oils are appropriate for centrifugal styles.
- Material Compatibility: Stainless steel or cast iron with thermal-resistant coatings is ideal.
- Mechanical Seal Arrangement: Select single or double mechanical seals depending on leakage tolerance.
- Serviceability & Spare Availability: Always prefer suppliers with local service facilities and parts available locally.
- Energy Efficiency: Select pumps with optimised hydraulics and minimum NPSH (Net Positive Suction Head) requirements.
