Pumps in general do a much better job of pushing than pulling and the amount of vacuum they create to self prime is limited and changes a LOT as the pump size increases


I work with a pump series for example that comes in size 15/30/60/130 etc

The size 15 will not self prime worth a poop were the 60 might have no issue pulling material up 6'
