A Danfoss 90 series piston pump (and other similar models like Danfoss MPV046 Axial Piston Pump or Danfoss Hydraulic Piston Pump Jjr045 Bl) is a high–performance axial piston hydraulic pump designed to convert mechanical power into controlled hydraulic fluid flow and pressure for heavy-duty systems.
These pumps use multiple pistons arranged around a rotating cylinder block with a swash plate to vary flow and pressure as needed. This makes them ideal for mobile and industrial hydraulic applications where precision, efficiency and durability matter
