Layout
Centrifugal, single-stage, vertical submersible pumps, separate discharge pipe and shaft guide pipe.
The spiral pump body is divided in a plane perpendicular to the shaft line, the suction port is located in the pump axis and is immersed in the pumped liquid, the discharge port connected to the discharge pipe is directed radially upwards along the shaft axis.
Depending on the application, the structure may be equipped with closed or open rotors.
The pump shaft (split or not) placed in the guide pipe is guided in bushings which, depending on the pump operation, are lubricated with the pumped liquid or from an external source. The design of the pumps allows for various configurations with or without sealing.
