Considerations for selection of a slurry pump

Considerations for selection of a slurry pump.With numerous series and models of slurry pumps available, how do we choose the right one for our specific application? This involves the professional selection process for slurry pumps. Let’s discuss some key points regarding the selection of slurry pumps.

Firstly, we need to understand the material that we will be conveying, the working conditions, and the intended installation method. Next, we need to determine the required processing capacity or flow rate, as well as the total head or lift required for slurry transport.

1. Slurry pumps are primarily used to transport slurries containing solid particles. We need to select the appropriate material for the slurry pump based on the characteristics of the slurry. If the slurry contains a significant amount of solid particles and requires a pump with good wear resistance, then a slurry pump made of high-chrome alloy A05 material should be chosen. If the slurry contains fewer solid particles and mainly consists of mud, then a cast iron slurry pump would suffice. If there are a lot of solid particles but no sharp edges, then a rubber-lined pump would be suitable. If the slurry has high acidity or corrosiveness, then a pump made of A49 material can be considered.
2. Pump installation: If the slurry pump is to be installed above ground, a horizontal slurry pump should be selected. If the pump head needs to be submerged in the slurry, a submersible slurry pump is appropriate. If the entire pump needs to be immersed in the liquid at the site, a submerged slurry pump is suitable.
3. Determining the pump model: This requires considering the required flow rate and total head at the site. It is important to note that when calculating the total head, factors such as the horizontal distance of the pipeline, the diameter of the pipeline, and the presence of bends should be taken into account. These factors can affect the pump’s total head.
