1. cheaper, one mech seal
2. more flow, lower npsh requirements, less radial laoding on shaft, easier maintenance
3. splitcase are for high flow, low head situations, very dependable, fire pumps
end suctions are cheaper per HP usually, and much more plentiful in selection, used for everything under the sun.
4, See the above.
