Danfoss APP 3.5 pumps

Axial-piston pump for reverse-osmosis systems. Parameters use the checked Danfoss 2024.06 data-sheet revision. Tabulated flow belongs to the stated speed and maximum table pressure, not any arbitrary duty point. Sound is measured on a motor-pump unit at maximum pressure and speed, at 1 m under EN ISO20361/EN ISO3744; it is not a noise guarantee for every installation. Pump, drive, coupling, filtration and supply scope are agreed separately.

Selection and applicability

APP, APP W, APP S and ATEX articles are not interchangeable by name. Only the explicitly selected standard APP/APP W articles are shown. All barg values are gauge pressures. The 2024 dry mass is not the net/gross mass of a current article page; confirm revision and shipping mass before ordering. Tables state ambient 0–50 °C, section 8.1 states 2–50 °C; agree operation at 0–2 °C. Check fluid temperature and corrosion resistance against NaCl concentration. No exact IMPA code is confirmed for these additions.
