Engineers and operators on board vessels rely on high-pressure pumps for a variety of critical tasks, from firefighting and cleaning to hydraulic systems and humidification. Danfoss offers the PAH 4, a pump designed to supply water flow under high pressure. This pump utilizes the axial piston principle, resulting in a compact and lightweight design. The PAH 4 features self-lubrication through the water itself, eliminating the need for oil lubrication and minimizing maintenance requirements. This means no periodic service like changing lubricant or wear parts is needed. Constructed with non-corrosive materials for easy cleaning, the PAH 4 has few wearing parts, ensuring a long service life with consistently high efficiency. The pump’s fixed displacement design delivers flow proportional to the input shaft’s revolutions and pump displacement. The PAH 4 can handle continuous pressure up to 140 bar and intermittent pressure up to 180 bar. It can achieve a maximum flow of 5 liters per minute at 1500 rpm and weighs 4.4 kilograms in stainless steel.
