Will changing the rotation speed of the mortar pump impeller and pump body reduce the erosion of the pump body by the material?

The pump material is wear-resistant dual-phase steel. Is there a better wear-resistant material? Let’s try titanium now. https://bbs.hcbbs.com/forum.php?mod=image&aid=2354177&size=300x300&key=28e3254e25c59f29&nocache=yes&type=fixnonehttps://bbs.hcbbs.com/forum.php?mod=image&aid=2354179&size=300x300&key=4d3833cc80be5c7b&nocache=yes&type=fixnonehttps://bbs.hcbbs.com/forum.php?mod=image&aid=2354178&size=300x300&key=adc33fef3c096b77&nocache=yes&type=fixnonehttps://bbs.hcbbs.com/forum.php?mod=image&aid=2354181&size=300x300&key=3b9a9b933a421ee7&nocache=yes&type=fixnone
If the rotational speed is too high, you can choose a 4-pole or 6-pole motor, and the wear speed will be reduced.
It looks like there is not only wear and tear, but also corrosion and cavitation.
The temperature is a bit high and the sodium sulfate solution is a bit corrosive
Now we have used down-frequency
Don't make trouble with this frequency reduction. Can Yang Cheng still meet the requirements?
What I mean is that you should consider it when you first choose a pump.
