Southern Cross designs and manufactures a range of standard and special inline vertical multistage pumps called the PVMI Series. These pumps offer great savings on floor space. But more than this, vertical multistage pumps provide high pressure and a wide range of flows. They are suitable for transferring low viscosity, non-inflammable and non-explosive fluids, and liquids that do not contain solids or fibres.
Multiple pumps can also be assembled and customised as a turnkey pumping solution or automatic pressure system called PVMIE System.
A vertical multistage pump is a centrifugal pump containing two or more impellers. The impellers may be mounted on the same shaft or on different shafts, but for most pumps, they are on the same vertically positioned shaft. The fluid flows into the inlet of the pump casing where it flows into the eye of the impeller. The rotation of the impeller creates centrifugal force which directs the fluid along the impeller vane and pushes the fluid to the outer tip of the impeller vane where it enters the stage diffuser. The diffuser is what leads the fluid into the suction eye of the next impeller. This process continues until the fluid has passed through each impeller stage. The fluid is then directed out the pump casing through a final diffuser and into the pump discharge.
