What kind of pump is suitable for transporting chemical liquids containing particles?

In some mixtures, the substance distributed in the liquid material is not dissolved, but is only dispersed in it. Once the mixture stops oscillating, it will precipitate. This inhomogeneous and heterogeneous mixture is called suspension. How is such a complex medium transported? What kind of chemical pump can meet the requirements?

Some staff with no specific experience will choose magnetic pumps, submerged pumps, stainless steel magnetic pumps and other pumps. In the past, these pumps wear out quickly in use, so the maintenance cost of replacement parts is high, and the overall reliability of the pump is poor. Today we come to a simple analysis of the reasons for the wear of the suspension transfer pump (fluoroplastic pump), the corrosion-resistant and wear-resistant mortar pump produced by RISTER. It greatly improves many problems in suspension transportation, improves the overall performance of the pump, and extends the effective life of the pump. The reason why the suspension will wear on the pump is that abrasive wear occurs when hard particles move in the pump. For example, abrasive wear exists on the back of the impeller, neck tube, rear plate, impeller inlet and pump suction pipe.

When conveying suspended slurry particles, erosion will also occur in the tube or inside the pump shell. The main cause of erosion is the impact of fine particles in the medium, which is also caused by the impact of suspended particles in acid-alkaline fluids on the surface of the pump. In fact, this has something to do with the material in the pump shell. Corrosion is a comprehensive phenomenon. There are many types of corrosion, they are: uniform corrosion, electrochemical corrosion, crack corrosion, pit corrosion, intergranular corrosion, stress corrosion and impact corrosion. As erosion and corrosion are often difficult to distinguish at the same time, we should pay attention to this problem in the material of the pump. According to the above summary, the mortar pump produced by RISTER PUMPS is specially aimed at, the overcurrent material is lined with ultra-polymer composite polyethylene (UHMW-PE), and the steel castings are used to improve the strength.
