   Vertical Turbine Submerged Centrifugal Pump is a  Vertical turbine design (also known as wet pit, diffuser) with diffuser vanes in the pump bowl. Flow follows the axis of the pump shaft. The API 610 designation for this type of pump is VS1. This pump is used if there is insufficient NPSHA for a horizontal pump. Therefore, the VS1 pumps are supported above the medium to be pumped. The vertically oriented impellers are suspended below the support and are submerged into the medium.  VS (Vertically Suspended) Pumps can be single or multistage and in theory can work to a limitless depth. VS1 pumps achieve this through the ability to have multiple stages stacked one on top of the other (see Figure 2). They can achieve a lower Net Positive Suction Head (NPSH) by designing for this specifically in the first stage and then follow it up with unique high head per stage series hydraulics in subsequent stages.

API 610 VS1 Pump
The fluid is pumped from the sump through the support column and out into a discharge bend. The sharp bend on the discharge however produces a loss in performance. The VS1 pump generally requires a double mechanical seal and Plan 53 seal support system to prevent leakage.
