The data sheet is valid for PAH pumps both non
ATEX and ATEX certified . The ATEX certified
versions are indicated with Ex in the designation .
The Danfoss range of PAH high-pressure pumps
is designed to supply water flow under high-
pressure for a varity of tap water applications .
Danfoss PAH pumps are positive displacement
pumps, with axial pistons that move a fixed
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 flow at a given speed no matter what
the discharge pressure .
All components are designed to provide long
service life with a constantly high efficiency and
minimum service required .
In the following all pumps are named PAH .
