The 180B0040 pump belongs to the PAH Displacement Pumps series and is produced by Danfoss. It supplies consistent flow to hydraulic automation circuits by converting rotational input into volumetric delivery. A fixed displacement of 63 cm³ per revolution establishes the volume transferred on each shaft turn, while a speed limit of 1800 rpm defines the mechanical ceiling for continuous duty. Within this envelope, the unit provides a flow range from 37.2 to 106.8 l/min so designers can match output to actuator demand. The inlet port is sized at 1 1/2 in and the outlet port at 1 1/4 in, allowing straightforward connection to standard hydraulic piping. Inlet pressure can reach up to 4 barg, ensuring stable feed conditions at the suction side.
Outlet pressure capability extends to 160 barg, enabling the pump to drive components such as intensifiers or high-pressure manifolds without external boosters. The housing is built from AISI 304 stainless steel for corrosion resistance, and dynamic sealing surfaces use NBR material to contain the working fluid. Acceptable ambient conditions lie between 0 °C and 50 °C, while the handled media must remain within 2 °C to 50 °C to maintain viscosity and seal life. A 1/4 in drain connection evacuates case leakage to a reservoir and prevents shaft seal overload. During operation the acoustic emission is 80 dBA, supporting compliance with typical plant noise targets. These characteristics define installation limits and service parameters for automated hydraulic systems.
