The 180B6091 pump is part of the PAHT G High Pressure Pumps series from Danfoss and is intended to supply pressurized water or hydraulic media to automated tools and cylinders. With a geometric displacement of 308 cm³ per revolution, it determines the volume transferred each time the shaft turns and guides the sizing of the drive motor. At its ceiling speed of 1250 rpm the pump can deliver 354.2 liters per minute at maximum outlet pressure, giving large flow for rapid actuator cycles, while at the minimum permitted speed of 450 rpm it still produces 107.8 liters per minute to sustain low demand stages. A maximum outlet pressure rating of 120 barg enables the unit to power intensifier circuits, whereas the minimum discharge pressure of 30 barg maintains seal integrity during idle operation. Mechanical efficiency of 0.95 limits heat generation and reduces input power requirements, supporting energy-conscious installations.
For system integration the pump develops 661.3 newton-meters of torque at the 120 barg condition, so the prime mover must be selected to match this load. The inlet side may be exposed to peaks up to 10 barg, which governs the specification of feed pumps and filtration lines. Reliable service is possible in rooms up to 60 °C ambient, and the unit accepts working fluid temperatures between 2 °C and 50 °C, covering chilled and moderately hot media. A continuous operating threshold of 700 rpm prevents lubrication starvation during long duty periods, complementing the wider operating band defined earlier. When running it generates a sound pressure level of 87 dB(A), a value used for enclosure and hearing protection planning. The assembly weighs 105 kg, so mounting structures must accommodate this static load without distortion.
