Danfoss PAH F high-pressure pumps are designed for tap water. PAH F pumps are developed for fire fighting applications. The pumps use only water as lubricant – no oil is needed which makes it possible to avoid any kind of contamination. The PAH F pumps offer up to 500 hours service intervals. In case the pump is not in operation, the 500 hours correspond to 10 years in stand-by position with ongoing performance tests.
