nnnn

through optimization of the port plates and the impeller.

Improvements to internal flow channeling reduce the energy

nnnn

requirements by 6 to 8%.

Optimization of the shaft bearings increases pump flexibility in

nnnn

the event of operational malfunctions and, ensures better

lubrication, which extends the service life. An optional

nnnn

connection for rinsing the housing is also available. This feature

improves cleaning and the service life.
