How to choose a suitable slurry pump?

Slurry pump is one kind of centrifugal pump used for convey water and solid mixture medium,It can be used in mining, electric power, metallurgy, coal, environmental protection and other industries to transport slurry containing abrasive solid particles. Due to the general presence of solid particles in the transport medium and the poor application conditions, the service life of slurry pumps is generally low, which can lead to a lot of downtime as well as expensive maintenance and spare parts, so it is particularly important to choose a suitable slurry pump. 1.Determine the model according to the site working conditions…

How to choose the right dredge pump parts?

Dredge pumps are widely used in river dredging, dredging and sand absorption and other engineering industries, and mud wear and cavitation are two of the most common reasons for the decline in performance and shortened service life of dredge pumps. This phenomenon leads to performance problems with the pump on the one hand, and on the other hand can damage pump parts (impellers, volute etc.) and even damage the pump foundation and piping system. Replacing defective parts not only increases maintenance costs, but also increases downtime and production losses. So choosing the right pump parts is crucial to the…

Heavy duty wear resistant material sand dredging pumps

Recently, we completed two ZN450 dredging pumps and 18-16T-ZG gravel pumps for our customers. These two pumps are mainly used for sand pumping, dredging and other highly abrasive application projects. The main wear parts are made of high-chromium alloy, which has good wear resistance. In sand mining, river dredging and other similar working conditions, a strong wear-resistant pump is one of the main equipment, in order to choose a most suitable pump, we will simply compare the two different types of pump Zidong pump industry. First of all, the main wear parts of the two pumps both are wear-resistant…
