180B1005

The 180B1005 pump belongs to the PAHT G High Pressure Pumps series and is manufactured by Danfoss. It is used to supply stable high-pressure water to hydraulic automation circuits. A geometric displacement of 4 cm³ per revolution sets how much fluid the pump delivers each shaft turn, which lets system designers match flow to actuator demand. The unit reaches a maximum outlet pressure of 100 bar so it can drive components that require elevated working pressures, while a minimum outlet pressure of 10 bar keeps the internal check valves seated during low-load conditions. Operation begins at a minimum speed of 1000 rpm, establishing the lowest permissible motor setting for continuous service. At this speed the pump generates 3.0 liters per minute under full pressure, giving predictable flow for small hydraulic manifolds. Five pistons share the load across the drive shaft, reducing pulsation and extending bearing life. The assembly weighs 4.4 kg, light enough for direct mounting on compact machine frames.

Running the shaft at 1500 rpm raises the maximum-pressure flow to 5.0 liters per minute, a value used when faster cylinder response is needed. A peak inlet pressure of 4 bar limits the boost supplied by the feed pump so the inlet seals are not overloaded. Torque demand at rated pressure is 8.1 N·m, which guides electric motor sizing and overload protection. The housing is made from AISI 304 stainless steel, providing corrosion resistance in water-borne installations. High-pressure discharge leaves through a G 1/4 × 11 threaded port that simplifies connection to stainless tubing, while returned fluid is routed back through a G 1/2 × 15 tank port sized for low velocity and minimal back pressure. Air trapped in the head is released via an M6 bleed port, facilitating quick commissioning after maintenance. During operation the sound pressure level remains 76 dB(A), enabling integration into plant areas that follow standard industrial noise limits.
