The 180B6090 pump belongs to the PAHT G High Pressure Pumps series from Danfoss and supplies pressurized media for hydraulic automation circuits. Its displacement of 256 cm³ per revolution defines the volume moved during each shaft rotation, forming the basis for calculated flow at any speed. When the shaft turns at the minimum speed of 450 rpm, the pump delivers 89.6 l/min, a rate suited to low-demand cycles. Operation is permitted in ambient temperatures from 0 °C up to 60 °C, so the unit functions in unheated or warm machine rooms. The wetted components accept media temperatures between 2 °C and 50 °C, which covers cold process water and moderately warm fluids. A running limit of 1250 rpm allows rapid flow response when higher throughput is required.
At 1250 rpm the pump supplies 294.4 l/min, supporting fast hydraulic cycles in high-productivity equipment. The inlet side tolerates peak pressures to 10 bar(g) to avoid cavitation during supply surges, while the outlet port withstands working pressures up to 120 bar(g). Designers must maintain at least 30 bar(g) outlet pressure to minimize internal slip and respect a continuous speed threshold of 700 rpm to keep bearings lubricated under light load. Driving the shaft at maximum pressure requires 549.6 N·m of torque, a figure that guides motor sizing. During service the unit generates a sound pressure level of 82 dB(A) at 1 m, indicating the need for hearing protection in confined areas. A weight of 105 kg determines lifting and mounting provisions for machine builders.
