Lifting Of The Canned Vertical Turbine Pump (double shell centrifugal pump with a Can or barrel)

To avoid distortion, The Canned Vertical Turbine Pump (double shell centrifugal pump with a Can or barrel) unit should be lifted as shown.

Depending on the pump size the pump unit is packed separately from the Can, or is put partially into the Can.

A crane must be used for all Canned Vertical Turbine Pump (double shell centrifugal pump with a Can or barrel) sets in excess of 25 kg (55 lb). Fully trained personnelmust carry out lifting, inaccordance with localregulations. The driver and pump weights are recorded on their respective nameplates.

In some cases the Canned Vertical Turbine Pumps (double shell centrifugal pumps with a Can or barrel) are not complete assembled (refer to section 4, Installation).

If Can and supporting flange are delivered separately, lifting shall be performed as follows:

Suction barrel (also referred as‘Can’) is supplied together with supporting flange and has to be installed into the sump first. Suction barrel and supporting flange are delivered assembled together. 4 distance sleeves are installed to fix both parts together.

Install 4 lifting screws (also referred as ‘Eye Bolts’) on the supporting flange and attach slings and straps to bring the suction barrel to a vertical position. Move the barrel for installation. Provide hand support to prevent the suction barrel from swaying during movement.

Distance sleeves are only used for fixing the base plate during transportation.

Lifting for preparation of insulation

If the application is configured for cold applications greater than -20°C, an insulation shall be provided on the suction can. The installation has to be performed in vertical lifted position to ensure that no damage can occur during transportation.
