The 180B0047 displacement pump is manufactured by Danfoss for the PAH Displacement Pumps series. It supplies pressurized hydraulic media for automated water or coolant systems in industrial machinery. Its housing is machined from AISI 304 which resists corrosion in aqueous fluids. The pump moves 50 cm³ per revolution, giving predictable volumetric delivery for flow calculations. The suction port uses a 1 1/2 in BSPP thread and the discharge port is sized at 1 1/4 in BSPP thread, allowing straightforward integration with standard piping. Operation is allowed from 700 to 1800 rpm, producing between 32 and 87.1 l/min so users can match flow to actuator demand.
The inlet can tolerate up to 4 barg, ensuring sufficient net positive suction pressure when supply tanks are remote. Outlet pressure is controlled between 30 and 80 barg to drive cylinders or nozzles that require high force. The working fluid temperature may range from 2 to 50 °C, enabling use with chilled or mildly heated media without degrading performance. Dynamic sealing components are manufactured from NBR, providing chemical compatibility with common water-glycol blends. The sound pressure level is 80 dBA, so installations may need acoustic panels in noise-sensitive environments. A net weight of 30.5 kg allows the pump to be mounted by one technician using light lifting equipment.
