VERTICAL pumps Vertical immersible sump pump. The pump body is immersed into the liquid and the motor is mounted above the plate, keeping it away from the liquid. The discharge pipe is separated from the column pipe and the lubrication of the bearings is normally obtained by means of the same pumped fluid, or from an external lubricating source in abrasive services. The possibility to customize mounting plate shape and dimensions, discharge flange position and column lenght, allows designers and end-users to match sump or tank plates or flanges. Suction strainer and suction extension on request. Use Vertical pumps are used in all industrial applications, refining, oil and gas production, chemical, pulp and paper and water facilities. They are also used in drainage sumps, oily water sumps and tank transfer. Construction Versions A arrangement: Lubricated by means of pumped fluid. Pumped fluid lubricates all the bearing bushes; the liquid must be clean, otherwise solids could clog the small pipes for intermediate bearing bush lubrication. B arrangement: Lubricated by external lubricating source. A clean external source, clean liquid or grease, lubricates all the bearing bushes. Used when the liquid is dirty, sticky or with suspended solids. This arrangement allows the pump to work without liquid in the sump or with suction extension. The external fluid is pumped togheter with the main fluid. E arrangement: Lubricated by fluid into the pipe column. Used when the liquid is aggressive, dirty, sticky or with suspended solids; a mechanical seal is placed between the shaft and the casing cover to fill the pipe column. All the bearing bushes are lubricated by flushing fluid.
