A2FO32 Plunger Set (7 pcs) 

The A2FO32 plunger set (7 pcs) is a critical spare part for axial piston pumps, specifically designed for Rexroth A2FO series hydraulic pumps. As one of the core components of the piston pump, the plunger directly determines the pump’s volumetric efficiency, output stability, and service life. Each set contains 7 pieces, manufactured from high-strength alloy steel, carburized, quenched, and precision ground for superior wear resistance, sealing performance, and durability under high pressure and high-speed working conditions.
