This design avoids sudden pressure fluctuations and impact during flow direction switching, reduces mechanical wear of internal components, extends the service life of the pump, and ensures smooth and steady operation of the hydraulic system during forward and reverse operation.<\/p>\n<p>3.High-pressure relief valves with integrated boost function, which not only play a role in overpressure protection to prevent damage to the system caused by excessive pressure but also integrate the boost function, realizing the integration of multiple functions, reducing the number of independent components, and lowering the system cost and maintenance difficulty.<\/p>\n<p>4.With adjustable pressure cut-off as standard, allowing users to flexibly adjust the pressure cut-off value according to actual working conditions and load requirements, ensuring the pump operates within the safe pressure range, and adapting to different application scenarios to improve the versatility and applicability of the pump.<\/p>\n<p>5.Through drive for mounting of further pumps up to same nominal size, providing a convenient and compact installation solution for expanding the hydraulic system. It enables the installation of additional pumps of the same nominal size without redesigning the drive structure, enhancing the expandability of the system and meeting the needs of large flow or multi-circuit oil supply.<\/p>\n<p>6.Large variety of controls, including manual, hydraulic, electric and other control modes, which can be selected according to the actual control requirements of the equipment, realizing flexible and precise control of the pump, and adapting to different operating environments and control systems.<br \/>\n<!-- prance-product-optimization --><\/p>\n<section class=\"pls-product-buyer-guide\">\n<h2>Selecci\u00f3n y solicitud de cotizaci\u00f3n<\/h2>\n<p>Esta serie de productos debe seleccionarse en funci\u00f3n del circuito hidr\u00e1ulico aprobado.
