Slurry pump wear factors
Slurry pump wear factors
(OP)
There are many factors affecting slurry pump wear. In connection with settting up tests to verify the performance of a particular pump, I am trying to establish the influence of each factor. Such as: Wear is linear to the solids concentration. Wear is proportional to the velocity squared and so on. Is anybody familiar with good references for this topic: Different sources lists different parameters, so there seems to be some disagreement out there as to what the effect of the various parameters is.

Due the the infinite number of variables it is unlikely that a "one rule" will fit all cases.
For a known solids slurry that has been pumped and documented previously it is possible to make some informed judgement for a similar application, other than this it probably guesswork.

For pipelines wear is proportional to velocity to the power 2.5 to 4.5. The criteria inviolved include temperature, pH, solids % , solids density, size of particles, size distribution, any chemical reaction, hardness, shape, carrier fluid, hours operating vs stationary, pump materials, tip speed, suction conditions etc etc.

"Weir"-something might be the parent.

Trust the info so far has been of help, more info from yourself should generate more useful information.

The have a slurry pump handbook, too. It is not available for free download but I think it is free of charge. You just need to be registered.
