It uses high-strength cast iron materials and a specialized internal noise reduction structure, greatly lowering operating noise to achieve ultra-low noise operation. The equipment features extremely low flow and pressure pulsation, sustaining stable flow and pressure output stably during low-speed operation. Built with a high-pressure structure, its maximum working pressure reaches 35 MPa. It supports a wide operating speed range with a top speed of 3000 r\/min and can be assembled into a duplex pump for combined use. In addition, the pump has excellent oil pollution resistance, effectively reducing component wear and extending overall service life. It is widely applicable to hydraulic systems of plastic machines, shoe machines, die-casting machines, forklifts and other industrial equipment, and is especially suitable for servo variable-frequency driven energy-saving hydraulic systems.<\/div>\n<\/div>\n<p><!-- prance-product-optimization --><\/p>\n<section class=\"pls-product-buyer-guide\">\n<h2>S\u00e9lection et DPX<\/h2>\n<p>The HG internal gear pump is commonly evaluated for injection molding and related servo hydraulic circuits where stable flow and compact installation matter.<\/p>\n<h3>Informations \u00e0 inclure dans votre demande de devis<\/h3>\n<ul>\n<li>Machine type and required flow range<\/li>\n<li>Working pressure and fluid specification<\/li>\n<li>Mounting and coupling details<\/li>\n<li>Control system interface and duty cycle<\/li>\n<\/ul>\n<h3>Ressources associ\u00e9es<\/h3>\n<ul>\n<li><a href=\"https:\/\/prancehydraulic.com\/fr\/applications\/hg-is-used-in-injection-molding-machines-with-servo-systems\/\">HG in Injection Molding Machines<\/a><\/li>\n<li><a href=\"https:\/\/prancehydraulic.com\/fr\/blog\/what-is-the-function-of-a-hydraulic-pump-for-servo-system\/\">Hydraulic Pump for Servo System<\/a><\/li>\n<\/ul>\n<p><a href=\"https:\/\/prancehydraulic.com\/fr\/contact-us\/\">Demander un devis<\/a> \u00b7 <a href=\"https:\/\/prancehydraulic.com\/fr\/download-center\/\">Centre de t\u00e9l\u00e9chargement<\/a> \u00b7 <a href=\"https:\/\/prancehydraulic.com\/fr\/oem-odm\/\">OEM \/ ODM<\/a><\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"<p>1.The axial and radial pressure compensation design is adopted to maintain high volumetric efficiency even at low speed and low viscosity.
