Description:
Vertical centrifugal pump for wet installation
The pump is driven by a three-phase motor via a flexible coupling.
The drive shaft is mounted in the inner tube and sealed by a mechanical seal against the
liquid. The closed impeller conveys the liquid between the inner tube and the outer tube to
the pump outlet.
Field of application:
Conveying chemically aggressive liquids in the whole range of the chemical industry and
process engineering, the metalworking and galvanic industry as well as the water treatment
and wastewater technology.
The pump can be used for stationary or portable applications.
Characteristics:
Not safe to run dry, not for continuous use; motor changeable,
permanently lubricated shaft bearing; mechanical seal in the liquid area
