Features intelligent one-button operation. Simply press the Start button to automatically perform bolt tightening or loosening, allowing operators to complete bolting tasks quickly and efficiently.<br \/>\n2. Features a high-efficiency three-stage pressure and flow design, providing fast movement under light load and slower, controlled operation under heavy load for more accurate bolt preload control.<br \/>\n3. An integrated electronic control system and digital pressure gauge use real-time pressure signals to control directional switching, providing fast response and high operating efficiency.<br \/>\n4. Equipped with a high-power brushless motor for reduced maintenance and long service life. The motor is fitted with a starting capacitor, allowing reliable starting under load.<br \/>\n5. After the target pressure is preset, the pressure gauge controls the directional valve automatically, reducing frequent operation of the pressure regulating valve and helping extend its service life.<br \/>\n6. Provides high operating speed and efficiency, with working efficiency more than 30% higher than conventional automatic pumps.<br \/>\n7. Equipped with a high-performance cooling system. When the hydraulic oil temperature reaches approximately 35\u00b0C, the cooling fan starts automatically to support long-duration continuous operation.<br \/>\n8. The oil reservoir and pump body are manufactured from aluminum-titanium alloy, providing a lightweight and portable structure.<br \/>\n9. Equipped with a 100 high-precision pressure gauge to support accurate torque control during hydraulic torque wrench operation.<br \/>\n10. Output pressure can be freely adjusted within the range of 40\u2013700 bar.<br \/>\n11. Equipped with an integrated cooling system for continuous operation for up to 24 hours under suitable working conditions.<br \/>\n12. Motors with various voltage and frequency configurations are available according to customer requirements.<br \/>\nCompatible Equipment<br \/>\nSquare Drive Hydraulic Torque Wrenches<br \/>\nLow-Profile Hydraulic Torque Wrenches<br \/>\nHeavy-Duty Sockets<br \/>\nReducer Sleeves \/ Adapter Sleeves<br \/>\nHigh-Pressure Hydraulic Hoses<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Product Overview The pump features automatic switching  [&hellip;]<\/p>\n","protected":false},"featured_media":612,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[18],"product_tag":[],"class_list":["post-1070","product","type-product","status-publish","has-post-thumbnail","product_cat-hydraulic-pumps","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product\/1070","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/comments?post=1070"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/media\/612"}],"wp:attachment":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/media?parent=1070"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product_brand?post=1070"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product_cat?post=1070"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product_tag?post=1070"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
