The chief benefit of a vertical turbine pump
The chief benefit of a vertical turbine pump is its small footprint and relative size to horizonal pumps. These pumps are suitable for spaces where available surface area is restricted or insufficient for a horizontal pump.
Unlike with a horizontal pump, the Net Positive Suction Head (NPSH) can be increased on a vertical centrifugal pump. This also makes vertical pumps more applicable for higher pressure fields.
The drawbacks of vertical pump design are expense and balancing concerns, especially at high suction pressures. Accumulation of high dissolved gases can wane efficiency as venting becomes difficult and less effective.
