What type of impeller pump should be chosen for a pump with a solid content of 50%?
Thread Content
Media: water, ammonia, ammonium thiocyanate, sodium thiosulfate, sulfuric acid, small amounts of tar, etc. Solid content 50%, temperature 50, specific gravity 1.45; the impeller should be made of 2205 material, and the pump should be made of 316L material. What suitable pumps are available?
The other party wants an impeller pump. Positive displacement pumps, reciprocating pumps won’t work. It’s very difficult
Impeller pumps are prone to clogging and wear; hose pumps are the most suitable choice
Use a mortar pump; you should call it a UHB, one with a low rotation speed, and it will work.
It is recommended to look into “slurry pumps”; however, there should be material requirements as well, for reference.
For slurry pumps, high-chromium alloys are generally used, as they offer excellent wear resistance.
The client specified that 316 material should be used, and that the impeller must be made of 2205
Then the full-open version at speed level 4, with 54 or 32 – there’s definitely no problem
There’s no problem with the slurry pump; this is the type used in the ammonium sulfate crystallization pump
