What is the temperature range of the working medium for IR centrifugal hot water pumps?
Thread Content
Dear HaiChuan team, I have a question I’d like to ask you. Regarding IR centrifugal pumps, some online sources state that the operating temperature for the medium should be below 120°C, while others mention 150°C; Baidu Baike says it should be below 180°C. Which of these figures is correct? Or do different manufacturers have different technical requirements? ? ?
IR: Used for transporting hot water or liquids with physical and chemical properties similar to those of water, with a medium temperature of ≤150°C. Structural features: This series is designed for horizontal installation, with suction occurring in the horizontal direction and the discharge outlet facing vertically upward. (For IY-type pumps, viewed from the suction side, the discharge outlet can face to the right, to the left, or upward.) During maintenance, it is not necessary to remove the inlet and outlet pipelines in order to access the rotor components for repair. The shaft seal can be either a packing seal or a mechanical seal, depending on the application. Depending on the intended use, the materials used for these pumps include ordinary cast iron, wear-resistant cast iron, cast steel, and cast stainless steel. The main components of this series of pumps include the pump body, impeller, sealing ring, impeller nut, pump cover, sealing elements, intermediate bracket, shaft, and suspension, etc. The material chosen for the pump determines the temperature of the medium it can transport.
