| The centrifugal immersion
pumps of building group 4 are
used for wet-pit operation in containers, pits and tanks.
Centrifugal immersion pumps for dry-well
installation, i.e. to be installed and operated
outside the container, are also available.

 Constructional design |
All components of pumps in plastic design that are in contact with the fluid are made of PP or PVDF. The pump shaft consists of a motor shaft made of stainless steel and a shaft-protecting tube of either PP or PVDF. Built-in elastomers are made of FPM (or also EPDM without surcharge). Centrifugal immersion pumps are equipped with overhang shafts so that there is no need to provide for shaft bearings in components that are in contact with the fluid. Thus, the pumps are safe to run dry and do not require regular service and maintenance.
There is no need of a mechanical sealing of the shaft. Only a so-called gas seal is installed beneath the motor to prevent aggressive vapours from penetrating the motor chamber. But this seal is never in contact with the fluid delivered.

To deliver liquids with a higher relative density, we also offer all our pumps with smaller impeller diameters which, however, reduce delivery rates and heads of the pumps. If in doubt, please consult us. |
