1. The volute pump is made of high-quality stainless steel such as 304 and 316L. The turbine can maintain stable performance in harsh environments, and is resistant to acid and alkali, high temperature and oxidation. 2. The volute pump is not easy to deform or break when running at high temperature and high speed, ensuring long-term and efficient operation of the equipment. 3. The lost wax casting (precision casting) process is adopted, and the volute pump has a smooth surface and high precision, which reduces airflow resistance.
