Pump selection – stuck in confusion, seeking expert advice
Thread Content
Flow rate required for the insulated magnetic pump: 50 m3/h. Head: 30 m. Material: 304 is not suitable, 316L is also not suitable; titanium has not been tried yet. Hastelloy is currently under consideration as the material for the insulation layer. The medium used is heat transfer oil, with a temperature of 260 degrees. Properties of the material: It operates at around 250 degrees. When the temperature drops below 100 degrees, the material becomes clumped and hard; at 200 degrees, it takes on an oily consistency. The main chemical component in this material is sacubitril benzene. The primary processing step is distillation in a tower. Before distillation, the concentration is 85%, while after distillation it drops to between 8% and 10%. At a concentration of 6%, the material is a viscous liquid at high temperatures, but turns into a solid at room temperature, similar to asphalt.

Screw pumps are absolutely not suitable; 316L is also not good enough
You can send the requirements and technical specifications for your pump to several large manufacturers of magnetic pumps; they will provide you with reasonable suggestions for selecting a suitable model based on your needs.
In the case of heat transfer oil, 316 is perfectly suitable; however, if acidic substances are present, a high-nickel alloy must be used. You can check www.shunda163.cn for more information
