PAH

The Danfoss PAH range of high-pressure pumps is specifically designed for high-pressure water applications using tap water, with firefighting systems being a key application.

PAH pumps are positive displacement pumps based on axial piston technology. The pistons displace a fixed volume of water during each cycle, resulting in a flow rate that is directly proportional to the input shaft speed (rpm). Unlike centrifugal pumps, PAH pumps deliver a consistent flow at a given speed, largely independent of discharge pressure.

The PAH range is designed for a variety of high-pressure water applications and is available in different pump sizes to accommodate different flow and pressure requirements.

This data sheet covers both non-ATEX and ATEX-certified PAH pumps. ATEX-certified versions are identified by “Ex” in the pump designation. In the following, all versions are referred to as PAH pumps.
