1. We can use various materials such as ductile iron, gray cast iron, aluminum alloy steel, carbon steel, etc. To manufacture durable steel valve body according to different needs of users. 2. Durable steel valve body uses a combination of sand casting and CNC processing technology to further improve the accuracy and surface smoothness. 3. Durable steel valve body has low resistance when fluid passes through and operates efficiently.

1. Pump casting parts have extremely small tolerances and smooth surfaces, reducing secondary processing. 2. Pump casting parts are made of excellent stainless steel materials, suitable for highly corrosive environments. 3. Pump casting parts adopt lightweight design to improve energy efficiency and reduce energy consumption. 4. Provide personalized customization services and design pump casting parts according to needs.

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.

1. Our iron casting valve body is made of ductile iron, which can improve the stability of the equipment. 2. The inspection process of iron casting valve body is strict, which can ensure the quality of the product. 3. We have a professional technical and service team for iron casting valve body, so you can enjoy worry-free after-sales!

1. Cast iron butterfly valve body is made of gray iron or ductile iron, which is not only low-cost, but also wear-resistant and corrosion-resistant. 2. The design of cast iron butterfly valve body is very precise and can meet the diverse needs of users. 3. The surface treatment of cast iron butterfly valve body after machining can effectively improve the corrosion resistance and other properties of the product.

1. Ductile iron casting pump parts, whether in raw material selection, casting process, or final CNC processing, we strictly follow international quality standards. 2. We at Hengrui have more than 20 years of experience in designing, producing and machining parts for Ductile iron casting pump parts. 3.
