180B0031

The 180B0031 pump belongs to the PAH Displacement Pumps series and is manufactured by Danfoss for hydraulic automation systems that require controlled high-pressure fluid delivery. Its AISI 304 stainless-steel body resists corrosion when the pump is installed in water-based or mildly aggressive circuits. A fixed displacement of 2 cm³ per revolution defines how much fluid is transferred with each shaft turn, which helps calculate required motor torque. The unit operates between 1000 and 3000 rpm so designers can match pump speed to drive capabilities without overspeeding the mechanism. At those speeds it produces flow rates from 0.7 to 4.1 l/min, enabling precise dosing or steady circulation as demanded by the process. Outlet pressure can be varied between 10 and 100 barg to support both low-pressure rinsing lines and high-pressure cutting or cleaning applications, while the inlet side tolerates up to 4 barg so feed pumps or elevated tanks can be used without risking cavitation.

A 1/2 in inlet connection simplifies coupling to common supply hoses, and a 1/4 in outlet port provides a compact high-pressure interface that keeps downstream pipework light. An M6 drain connection vents any internal leakage back to tank and prevents bearing washout. Acceptable media temperatures range from 2 °C to 50 °C, allowing the pump to handle chilled water or moderately warm process fluids without viscosity issues. An NBR seal set contains the fluid inside the housing and gives compatibility with standard hydraulic oils and water glycol mixtures. During operation the acoustic emission reaches 76 dB(A), a level that guides enclosure design or ear protection choices in plant environments. These connection details, thermal limits, sealing materials, and sound ratings complete the data set needed to integrate the 180B0031 pump into automated hydraulic installations.
