Product Overview

Product Overview

The High Temperature Oil Pump OH2 is a centerline-mounted, single-stage overhung centrifugal pump designed for thermal oil, heat transfer fluid and hot oil circulation services. Based on the API 610 OH2 configuration, the pump minimizes thermal deformation and maintains reliable hydraulic performance under continuous high-temperature operating conditions.

As part of our high temperature pump range, it is widely used in refinery heating systems, petrochemical plants, thermal oil boilers, chemical processing facilities and industrial heat transfer systems where stable operation and long service life are essential. For molten salt duties above 450°C, see our high temperature molten salt pumps.

  • Industrial Heating Media

Why Choose OH2 Design for High Temperature Service

Unlike conventional end-suction pumps, the OH2 design uses a centerline-mounted casing that allows the pump to expand evenly during temperature fluctuations. This significantly reduces shaft misalignment, vibration and seal failure risks when handling high-temperature fluids.

The robust bearing housing and heavy-duty shaft design further improve reliability in demanding thermal oil circulation systems. Learn more about our broader API OH2 process pump capabilities.

FAQ

Frequently Asked Questions

What Is a High Temperature Oil Pump?

A high temperature oil pump is a centrifugal pump specifically designed to transfer thermal oil and heat-transfer fluids under elevated temperatures.

What Is the Maximum Operating Temperature?

Depending on configuration and materials, temperatures can reach up to 450°C.

What Is the Difference Between an OH1 and OH2 Pump?

OH2 pumps use a centerline-mounted casing, making them more suitable for high-temperature applications than foot-mounted OH1 designs.

What Fluids Can Be Pumped?

Thermal oil, heat transfer fluid, synthetic oil and hot hydrocarbons.

Why Is OH2 Preferred for Thermal Oil Systems?

Because the centerline support design better accommodates thermal expansion and reduces vibration.

How Do I Select a Thermal Oil Pump?

Selection depends on temperature, flow rate, head, pressure and fluid characteristics. Tell us your project requirements and our engineers will recommend the most suitable OH2 solution. See technical specifications or contact us for support.
