The 180B6141 displacement pump is manufactured by Danfoss as part of the PAH Displacement Pumps series and supplies hydraulic media in automated systems that depend on steady volumetric flow. Its housing is formed from AISI 304 stainless steel to resist corrosion in water-based circuits. A fixed displacement of 80 cm³ per revolution ensures predictable delivery, simplifying flow control algorithms. The suction side is equipped with a 1 1/2 in inlet port that accepts standard pipe fittings, while a 1 1/4 in outlet port connects directly to pressure lines to minimize head loss. The pump can spin up to 1800 rpm for high output cycles, yet it remains stable down to a continuous 700 rpm when demand drops. At the upper speed it produces a maximum flow of 138.1 l/min, and it can reduce output to 49.7 l/min to match actuator requirements during low-load operation.
The unit tolerates an inlet pressure of up to 4 barg so it can draw from lightly pressurized reservoirs, and it delivers working pressures between 30 barg and 160 barg to power cylinders or hydraulic motors. Acceptable media temperatures span from 2 °C to 50 °C, covering chilled and moderate-temperature fluids while maintaining viscosity within design limits. NBR sealing elements contain these fluids and resist additives commonly found in water-glycol mixes. A net weight of 30.5 kg allows one person to position the pump with standard lifting aids and adds mass that dampens vibration once installed. Operating noise is held to 80 dBA, supporting compliance with typical plant acoustic guidelines. Together these characteristics give the 180B6141 pump the range and durability needed for automated hydraulic machinery that must sustain reliable flow under varying temperature, pressure, and speed conditions.
