The data sheet is valid for PAH pumps both non
ATEX and ATEX certied. The ATEX certied
versions are indicated with Ex in the designation.
The Danfoss range of PAH high-pressure pumps
is designed to supply water ow under high-
pressure for a varity of tap water applications.
Danfoss PAH pumps are positive displacement
pumps, with axial pistons that move a xed
amount of water in each cycle. Flow is propor-
tional to the number of input shaft revolutions
(rpm). Unlike centrifugal pumps, they produce
the same ow at a given speed no matter what
the discharge pressure.
All components are designed to provide long
service life with a constantly high eciency and
minimum service required.
In the following all pumps are named PAH.
