The Bosch Rexroth P A4VSG 250 MA /30W-PZB10N000N-SO304 (R902496681) is a high-performance axial piston variable pump designed for industrial applications requiring robust and reliable hydraulic power. This pump is notable for its exceptional service life and low operating noise, making it an ideal choice for environments where durability and minimal disturbance are key concerns. The P A4VSG 250 MA features a through-drive capability, allowing for the mounting of additional pumps up to the same nominal size, thereby facilitating versatile system configurations. The pump's design ensures that the flow direction changes smoothly when the swashplate moves through the neutral position, enhancing the operational efficiency of hydraulic systems. It boasts both axial and radial load capacity on its drive shaft, indicating a sturdy build capable of withstanding demanding conditions. The modular system design complements a range of application requirements while also offering maintenance convenience. Furthermore, this model includes a visual swivel angle indicator which aids in monitoring and adjusting operational parameters quickly and accurately. The short control response times are advantageous in applications where rapid system reactions are necessary. Additionally, this pump can be operated at high frequencies (HF) with a lower specification when required. With its swashplate design, the Bosch Rexroth P A4VSG 250 MA maintains high pressure performance consistently throughout its operation. It has been engineered to meet stringent metrics with a nominal pressure of bar and a maximum pressure bar capability within closed circuits. This metric version underscores its adaptability to various industrial hydraulic systems worldwide.
