What is a Thermal Hot Oil Pump (Water-Cooled)?

A thermal hot oil pump (water-cooled) is an industrial centrifugal pump designed to handle high-temperature thermal fluids while maintaining safe operating conditions through a water-cooled bearing housing. MRP Pumps & Seals manufactures these pumps specifically for circulating thermic fluids, hot oils, and high-temperature liquids in demanding process industries.

These pumps feature a robust shaft sealing system and a dedicated water-cooling arrangement that regulates bearing temperatures during continuous high-heat operation. By isolating heat from critical components, they ensure reliable performance in chemical processing, petrochemical plants, textile units, and other industries requiring efficient and stable high-temperature fluid circulation.

How Thermal Hot Oil Pump (Water-Cooled) Works

Understanding the operating principles behind our high-performance water-cooled thermal oil pumps
  • Primary Impeller Operation: The main impeller circulates high-temperature thermal oil, generating the required flow and pressure for process heating systems.
  • Heat Isolation Design: The pump construction minimizes heat transfer from the hot fluid to critical components, protecting bearings and sealing areas.
  • Water-Cooled Bearing Housing: A dedicated cooling jacket circulates water around the bearing housing to effectively dissipate heat during operation.
  • Temperature Control: This system maintains stable bearing and seal temperatures, ensuring reliable performance and extended pump life under extreme thermal conditions.

Thermal Hot Oil Pump (Water-Cooled) Selection Guide
