Description

Technical Field

[0001] This utility model belongs to the field of chemical pump technology, and in particular relates to a chemical pump with a filtration system. Background Technology

[0002] Chemical pumps are widely used in the chemical industry for conveying liquid materials. They require highly wear-resistant materials and excellent sealing to prevent safety hazards. However, in existing chemical process pumps, the pump body is always in contact with the medium during operation. The eddies and vortices generated by the rotating impeller inside the pump body exacerbate the wear at the circular tapered tube at the pump inlet. In severe cases, this area can be worn through, leading to leakage of the conveyed medium and affecting the safety of pump operation.

[0003] In addition, solid impurities in the liquid will continuously impact the impeller, gradually damaging the impeller surface and affecting working efficiency. In severe cases, they may even block the impeller flow channel, greatly reducing the pump's outlet pressure. At the same time, impurities in the liquid can also affect the pump's seal, causing leakage and creating safety hazards. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the rotation of the impeller in existing chemical pumps will aggravate the wear at the circular tapered tube at the pump body inlet, and the solid impurities in the liquid will also continuously impact the impeller, causing the impeller surface to be gradually damaged, affecting working efficiency, and in severe cases even blocking the impeller flow channel, greatly reducing the pump outlet pressure, causing the pump to leak and creating safety hazards. Therefore, a chemical pump with a filtration system is proposed.
