180B1132

The 180B1132 pump belongs to the PAH Displacement Pumps series and is manufactured by Danfoss for hydraulic automation tasks that require stable high-pressure delivery. It moves 4 cm³ per revolution, so engineers can calculate volumetric flow precisely from shaft speed. At 1 500 rpm the unit delivers 5.0 l/min, and a 1.5 kW motor at that speed supplies adequate driving power with moderate electrical load. Operating speed may be set anywhere between 1 000 rpm and 3 000 rpm, giving control systems a broad adjustment range. Outlet pressure is selectable from 30 barg to 100 barg, allowing the same frame size to serve both medium- and high-pressure circuits. When the pump is held at its 100 barg ceiling, the shaft transmits 8.1 Nm of torque, which guides coupling and key sizing. The housing is built from AISI 304 stainless steel to resist corrosion in water-based media, and the overall assembly weighs 4.4 kg, simplifying handling during installation or service.

Fluid enters through a G 1/2 BSPP inlet port that matches standard suction hoses, while the inlet side must not exceed 4 barg to protect internal components. Discharge leaves via a G 1/4 BSPP outlet, a smaller thread that suits the reduced volume flow. An ISO 3019-2 63A2HW mounting flange defines bolt pattern and pilot diameter so the pump fits common motor adapters without shims. Torque is transmitted through a 5 × 5 × 20 mm parallel key on the shaft, ensuring positive drive engagement under pulsating loads. FFKM sealing material is used on dynamic and static interfaces to maintain leak-free operation with aggressive fluids and elevated temperatures. These mechanical and connection details enable quick integration into compact manifolds and minimize assembly time by relying on BSPP threads with sealing washers. The clearly defined flange, key, and port sizes let maintenance crews replace the pump without realignment, supporting high equipment uptime. Finally, the robust sealing system complements the stainless housing to extend service life in continuous high-pressure duty.
