1. Temperature Range and Operating Conditions Requirements:

　　o Actual Temperature:This is the most critical element. 300°C, 400°C, and 500°C+ represent entirely different design requirements and material grades. The higher the temperature, the stricter the demands on material heat resistance, sealing structure, and cooling systems, with costs skyrocketing.

　　o Heating Medium Properties:The inherent properties of the thermal oil (viscosity, lubricity, thermal stability, oxidizing, and corrosive nature) affect material selection and pump design.

　　o Pressure Requirements:The higher the system pressure, the greater the strength requirements for the pump housing and shafting, resulting in higher prices.

　　o Stability Requirement:Do you require continuous 24/7 operation, or intermittent short-term runs? The requirements for reliability and redundancy differ.
