The 180B1044 pump belongs to the PAH Displacement Pumps series manufactured by Danfoss and supplies pressurized fluid for hydraulic automation systems. Its geometric displacement of 20 cm³ per revolution determines the volume transferred every shaft turn, while a maximum flow of 27 l/min supports medium-capacity circuits. The design withstands outlet pressures up to 100 bar so it can serve high-pressure tools and actuators. A required torque of 35 Nm at maximum pressure helps engineers size couplings and gearboxes correctly. The housing tolerates inlet pressures up to 20 bar, which permits connection to pre-pressurized feed lines. When operated at 1500 rpm, the drive must supply 5.5 kW of mechanical power to keep the pump within its duty rating.
The shaft speed can be increased to 2400 rpm for high-demand cycles, yet it will begin moving fluid from 700 rpm and should run at no less than 1000 rpm for continuous service to maintain internal lubrication. Outlet pressure must stay above 30 bar to prevent cavitation and sealing loss. During operation the unit produces a sound pressure level of 79 dB(A), a factor to consider when planning acoustic enclosures. A net weight of 18 kg enables single-person handling and simplifies installation. These combined speed, pressure, and acoustic characteristics outline the safe operating window for integrating the 180B1044 into automated hydraulic equipment.
