Intended use
The pressure increase pump for MELAdem47 enables the increase of the inlet pressure of the water treatment unit
MELAdem47.
The MELAdem47 can thus produce higher quantities of demineralized water (DI water) at low line pressure on the build-
ing side. The pressure increase pump is installed by trained service technicians. After the installation, the operation of
the pressure increase pump is automatic. The pressure increase pump must be operated together with the
MELAdem47. User groups and usage environment correspond to those of MELAdem47. The pressure increase pump
is intended for use in the medical field, e.g. in clinics, medical and dental practices outside the patient environment.
