Welcome to Rinku Engineers, a premier manufacturer and supplier of high-temperature fluid handling systems. Our specialized range of Thermic Fluid Pumps and Hot Oil Centrifugal Pumps is engineered to manage the circulation of heat-transfer oils and high-temperature liquids with absolute safety and efficiency. Designed to operate under extreme thermal conditions without the need for external cooling, our pumps are the cornerstone of modern industrial heating systems.
Our Specialized Pump Range
Thermic Fluid Pump
The Thermic Fluid Pump is the industry standard for closed-loop heating systems. It is designed specifically to circulate synthetic or mineral heat-transfer oils. By utilizing a “back pull-out” design, maintenance is simplified, allowing for quick inspection of the rotating parts without disturbing the hot oil pipelines.
Hot Oil Centrifugal Pump
Our Hot Oil Centrifugal Pump is engineered for versatility in high-temperature applications. Whether it is for frying oil in food processing or chemical heating, these pumps offer superior thermal stability. As a premier supplier, we ensure these units are tested for zero-leakage and consistent flow at elevated temperatures.
Industries We Serve
Our thermic and hot oil range provides reliable circulation for:
-
Textile Processing: Circulating hot oil for stenters, drying, and finishing machines.
-
Chemical & Pharma: Heating reactors and distillation units via thermal fluid circuits.
-
Food Processing: Reliable pumping of hot frying oils and thermal heating for industrial ovens.
-
Plywood & Laminates: Supplying consistent heat to hot presses and resin kettles.
-
Rubber & Plastics: Temperature control for injection molding and extrusion processes.
High-Temperature Solutions for Thermal Fluid Circulation
In industrial heating processes, managing hot oil at temperatures exceeding 300°C requires specialized engineering to prevent leakage and mechanical failure. As a leading manufacturer and supplier, we address these critical thermal challenges:
-
Problem: Seal failure and oil leakage due to extreme heat.
-
Solution: Our Hot Oil Centrifugal Pump features a unique heat-dissipating “cooling fin” design on the bearing housing. This naturally lowers the temperature near the mechanical seal, ensuring a leak-proof operation without requiring an external water-cooling system.
-
-
Problem: Bearing seizure and shaft misalignment caused by thermal expansion.
-
Solution: The Thermic Fluid Pump is built with high-quality, heat-treated bearings and a robust shaft assembly that can accommodate thermal expansion, maintaining perfect alignment even at peak operating temperatures.
-
-
Problem: High energy loss in heat-transfer systems.
-
Solution: Our precision-cast impellers are hydraulically optimized to ensure maximum circulation velocity with minimal power intake, keeping your thermal oil heaters running efficiently.
-
Technical Specifications & Features
-
Air-Cooled Design: Eliminates the complexity and cost of external water cooling for seals and bearings.
-
High-Grade Metallurgy: Constructed from S.G. Iron or Cast Steel to withstand thermal stress and pressure.
-
Back Pull-Out Construction: Simplifies maintenance by allowing the motor and rotating assembly to be removed while the casing remains in the line.
-
High Thermal Capacity: Capable of handling organic heat-transfer oils up to 350°C safely.
-
Dynamic Balancing: All impellers are precision-balanced to ensure noise-free and smooth operation at high velocities.

Frequently Asked Questions
Does a Thermic Fluid Pump require water cooling for the bearings?
No. Our Thermic Fluid Pumps are specifically designed for air-cooling. The specialized finned housing dissipates heat into the air, protecting the bearings and seals without the need for a separate water line.
What type of mechanical seal is used in Hot Oil Centrifugal Pumps?
We use high-grade, heat-resistant mechanical seals (often with specialized faces like Carbon vs. Silicon Carbide) that are specifically rated for high-temperature oil to prevent vapor leakage and oil seepage.
Can these pumps be used for frying oil in the food industry?
Yes. Our Hot Oil Centrifugal Pumps are widely used in the food industry for circulating edible oils at high temperatures, provided the materials of construction meet food-grade safety standards.
How often should the oil in the bearing housing be checked?
Regular maintenance is key. We recommend checking the bearing lubrication weekly, especially in 24/7 operations, to ensure the high-temperature bearings are properly protected.
