The 180B0007 displacement pump belongs to the PAH Displacement Pumps series and is manufactured by Danfoss for hydraulic automation circuits that require a controlled water supply. Its displacement is 12.5 cm³ per revolution, setting the volume moved each shaft turn for predictable flow calculations. A minimum operating speed of 700 rpm keeps internal lubrication reliable during light-load cycles, while a maximum speed of 1800 rpm permits faster duty when demand rises. The pump delivers as little as 7.2 l/min at low process loads and up to 20.9 l/min when full capacity is needed, giving designers a broad regulating window. A 3/4 in inlet port accommodates standard suction piping, and a 3/8 in outlet port connects to common high-pressure lines without additional adapters. The housing is made from AISI 304, providing corrosion resistance for installations that handle treated or raw water.
The pump tolerates inlet conditions up to 4 barg, enabling placement on systems where moderate supply pressure is present before the plunger stage. Downstream components are protected by a minimum outlet pressure of 10 barg, and the unit withstands discharge pressures up to 160 barg for high-pressure cleaning or cutting applications. Fluid temperatures can range from 2 °C to 50 °C, ensuring reliable sealing whether the water is near ambient or slightly warmed by upstream processes. A 1/4 in drain port allows any bypass or leakage fluid to be routed back to the tank, preventing case over-pressurization. NBR seals isolate the drive end from the wet end, supporting compatibility with typical water additives. During operation the sound pressure level stays at 75 dBA, aiding compliance with standard industrial noise limits.
