CNP CDM and CDMF Vertical Multistage Pumps
A vertical pump range for clean-liquid transfer and boosting.
View seriesCNP CDMF plus CMH High Pressure Pump Systems
Two pumps in series for higher-pressure clean-liquid duties.
The CNP CDMF plus CMH arrangement combines a CDMF supply pump with a CMH high-pressure pump in series. It is a distinct high-pressure configuration rather than a standard single CDMF pump. The supplied 50Hz catalogue includes paired models for reverse osmosis, treatment, washing and boosting applications, with pressure and inlet conditions that must be checked as part of selection.
