Things to consider

If you are pumping from a sump then the long shaft pump is a good option. Check that the pump can be got to and maintained easily.

If the long shaft pump has a mechanical seal then get an estimate on what it would cost to have the pump repaired. It is best to know these costs before something happens. Check the warranty conditions. These pumps work well with a stirrer combination. This helps with the dilution of the solids. Sand is very hard on these pumps and if not controlled can cause premature ware.
