COMBIPRESS "CB2"
Pressure boosting sets
CB2 - 2CP
CB2 - 4CP
OPERATING PRINCIPLES
CONSTRUCTION CHARACTERISTICS
COMBIPRESS are twin pump pressure boosting sets supplied preassembled and ready to install.
The sets are designed so that the pumps operate automatically in
succession as the demand for water increases.
This results in significant energy savings as the second pump only
runs at times of high demand.
The lead pump is alternated automatically by the control box.
