They transmit torque, maintain alignment, and prevent fluid leakage under high pressure, making them critical for the safe and efficient operation of industrial hydraulic systems.<\/p>\r\n<h2>Standard and Custom Flange Configurations<\/h2>\r\n<p>Manufacturers offer a range of flange types to suit different pump designs and system requirements. Standard configurations include bolted flanges with raised faces, flat faces, and ring\u2011type joints, each providing specific sealing characteristics. Materials range from carbon steel and stainless steel to alloyed grades for corrosion resistance. Custom options are available for non\u2011standard bolt patterns, oversized diameters, or special surface finishes, ensuring compatibility with legacy equipment or unique engineering specifications.<\/p>\r\n<h2>Key Industries and Typical Applications<\/h2>\r\n<ul>\r\n  <li>Mobile equipment hydraulics \u2013 excavators, loaders, and agricultural machinery.<\/li>\r\n  <li>Industrial machining \u2013 CNC machines, presses, and metal forming equipment.<\/li>\r\n  <li>Energy sector \u2013 offshore drilling rigs and wind\u2011turbine pitch control systems.<\/li>\r\n  <li>Construction \u2013 concrete pumps and tower cranes.<\/li>\r\n  <li>Marine and shipbuilding \u2013 ballast control and steering hydraulics.<\/li>\r\n<\/ul>\r\n<h2>Important Selection Criteria<\/h2>\r\n<p>When choosing flanges for hydraulic pumps, consider the operating pressure, temperature range, and fluid compatibility. Verify the bolt circle diameter, number of bolts, and flange thickness to match the pump\u2019s mounting specifications. Material selection should align with corrosion resistance needs, especially in aggressive environments. Finally, ensure the sealing surface (raised, flat, or ring) matches the gasket type recommended by the pump manufacturer.<\/p>\r\n<h2>Why source flanges for hydraulic pumps from Cohimar<\/h2>\r\n<p>Cohimar combines 40 years of hydraulic expertise with a comprehensive stock of leading\u2011brand flanges. Our technical team assists with fit\u2011verification and custom solutions, while our rapid logistics guarantee prompt delivery to keep your production line running.<\/p>\r\n<h2>Frequently Asked Questions<\/h2>\r\n<h3>What pressure ratings are typical for hydraulic pump flanges?<\/h3>\r\n<p>Standard flanges are rated from 150\u202fbar up to 350\u202fbar, with high\u2011performance alloys available for pressures exceeding 500\u202fbar.<\/p>\r\n<h3>Can I use a flange designed for a different pump model?<\/h3>\r\n<p>Only if the bolt pattern, flange diameter, and sealing face match the target pump. Mismatched dimensions can lead to leaks or mechanical failure.<\/p>\r\n<h3>Do you provide gasket recommendations for each flange type?<\/h3>\r\n<p>Yes, Cohimar\u2019s engineers advise the appropriate gasket material (e.g., NBR, PTFE, or metal) based on pressure, temperature, and fluid compatibility.<\/p>","faqs_schema":""},"_links":{"self":[{"href":"https:\/\/www.cohimar.com\/en\/wp-json\/wp\/v2\/product_cat\/381","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.cohimar.com\/en\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/www.cohimar.com\/en\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/www.cohimar.com\/en\/wp-json\/wp\/v2\/product_cat\/375"}],"wp:post_type":[{"href":"https:\/\/www.cohimar.com\/en\/wp-json\/wp\/v2\/product?product_cat=381"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
