1.	Introduction	The Danfoss range of PAHT C is specifically
		designed for use with technical water mixed with

chemicals or media other than water with low viscosity.

Danfoss PAHT pumps are positive displacement pumps, with axial pistons that move a fixed amount of water in each cycle. Flow is proportional to the number of input shaft revolutions (rpm). Unlike centrifugal pumps, they produce the same flow at a given speed independently of the discharge pressure.

The range of PAHT C pumps is based on the standard PAHT pump series. The PAHT C pumps are made with more resistant sealing. These pumps are primarily used in gas turbine water wash applications or other cleaning applications.

This data sheet is valid for PAHT C pumps both non ATEX and ATEX certified. ATEX certified pumps are indicated by Ex in the type designation example PAHT C 2 Ex.
