Piston pumps for aerospace applications encompass fixed- and variable-displacement axial and radial piston designs used to generate high-pressure hydraulic flow in flight-control, landing-gear, and actuation systems, operating with MIL-spec hydraulic fluids such as MIL-PRF-5606 and MIL-PRF-83282, and manufactured to stringent AS9100 quality requirements using precision-honed cylinder bores, swashplate mechanisms, and hardened slipper-pad assemblies.
