What happens if the inlet pressure of an axial piston pump is too low?

If the inlet pressure of an axial piston pump is too low, the most likely consequence is pump cavitation. Cavitation occurs when the pressure in the pump drops below the vapor pressure of the hydraulic fluid, leading to the formation of vapor bubbles. When these bubbles collapse, they can cause significant damage to the internal components of the pump, including erosion of the surfaces and potential failure of the pump.

Maintaining adequate inlet pressure is crucial for the proper functioning of axial piston pumps. It ensures that the pump can operate within its designed parameters, allowing for optimal flow and pressure generation. Low inlet pressure disrupts this balance and can compromise the overall system performance, leading to inefficiencies and potential breakdowns.

In contrast, low inlet pressure would not lead to an increased flow rate, improved efficiency, or lower operational noise. Instead, it hampers the pump's ability to function correctly and can result in costly repairs and downtime.
