1. Introduction	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.
