Water ring pump is widely used with complete specifications and strong adaptability. Ordinary material pumps can meet most of the use requirements, but due to the different nature of materials, some working conditions have higher requirements on the anti-corrosion performance of pumps, so the pumps need to be made of anti-corrosion materials, let's understand this aspect:
1. According to the vacuum degree and corrosiveness of the pumped gas, the material configuration of water ring pump can be divided into three categories:
(1) class B material, cast iron carbon steel common material;
(2) class E material, 304 stainless steel medium grade material;
(3) class H material, 316 stainless steel high-grade material.
2. According to different anti-corrosion requirements, the flow passage parts of water ring pump can be made of stainless steel of corresponding brand, or the user can select materials as required. When the pump body is lined with rubber, the corrosion resistance of the pump body can be improved. When the flow passage parts are sprayed with special materials, the smooth spraying surface can avoid the retention of impurities and improve the hydraulic efficiency of the water ring pump.
The main parts of the water ring pump can meet the strict anti-corrosion requirements after anti-corrosion treatment or manufacturing with anti-corrosion materials.
