180B6119

The 180B6119 pump is part of the PAHT G High Pressure Pumps series manufactured by Danfoss for hydraulic automation that requires compact, oil-free water pressurization. A geometric displacement of 20 cm³ per revolution defines how much fluid the pump moves on every shaft turn, allowing engineers to size the drive accurately. When the shaft turns at 1000 rpm, the pump delivers a flow of 16.9 l/min, and this rises to 27.0 l/min at 1500 rpm, giving predictable output for proportional control loops. A maximum outlet pressure of 100 barg enables high-pressure cleaning or reverse-osmosis skids, while the design also tolerates a minimum outlet pressure of 30 barg so downstream equipment always sees stable loading. The peak inlet pressure limit is 20 barg, which protects the internal check valves from excess suction line force. At full load the shaft must supply 21.0 Nm of torque, a figure used to match the pump to an electric motor or engine without risk of stall.

The mechanical envelope supports a maximum speed of 2400 rpm for applications that need short cycle times, and the unit can start as low as 700 rpm so variable-frequency drives may run it at reduced flow during standby. A minimum continuous speed of 1000 rpm provides the boundary below which bearing lubrication and valve timing become unreliable, giving designers a safe operating window. Driving the pump at 1500 rpm calls for a 5.5 kW motor, which simplifies power-train selection in standard IEC frame sizes. During operation the sound pressure level is 79 dB(A), information used to plan enclosure damping or hearing protection. Finally, a weight of 19 kg makes the pump light enough for single-person installation yet heavy enough to damp vibration in rigid piping assemblies.
