The 180B6187 pump is part of the PAHT G High Pressure Pumps series from Danfoss and is intended to supply pressurized fluid in hydraulic automation circuits. Its geometric displacement of 70 cm³ per revolution determines the basic flow yield for each shaft turn. When the shaft runs at 1000 rpm the pump delivers 57.7 l/min, matching moderate demand applications, while a rise to 1500 rpm increases flow to 92.9 l/min for higher throughput. The unit can start at a minimum speed of 700 rpm to allow flexible drive selection and may be driven up to 1800 rpm without exceeding mechanical limits. A maximum outlet pressure rating of 160 barg defines the highest system pressure the pump can generate, and the minimum outlet pressure of 30 barg keeps the internal sealing elements loaded during light duty cycles.
Drive sizing and installation constraints are addressed by further parameters. Continuous operation should not fall below 1000 rpm so the internal bearings maintain proper lubrication. The peak allowable inlet pressure is 20 barg, enabling placement on pressurized supply lines without risking housing distortion. Shaft load at maximum pressure reaches 191.8 Nm, a value used to select couplings and motor torque capacity. A motor rated at 30 kW is specified for 1500 rpm service, whereas 50 hp covers full speed operation at 1800 rpm. The assembled pump weighs 34 kg, affecting mounting structure design. During operation the sound pressure level is 86 dB(A), which guides enclosure or hearing protection requirements.
