Question re mine dewatering pump options. Looking at suppliers/models/single stage centrifugal/multi-stage. We have an underground transfer pumping duty. Flow rate is approx 100m3/h. Head will be in the order of 120m to 130m. Currently the lads are looking at sulzer centrifugal. Mine is long life. I would have thought a small multi-stage, or double suction would have been more appropriate rather than a high speed (2 pole speed) centrifugal that is going to beat itself to death in a short period. Any comments? Water will contain some small percentage of solids. Maybe 3%. Regards
