Features a high-efficiency three-stage pressure and flow design, simulating manual operating logic with fast movement under light load and slower, controlled operation under heavy load for more accurate bolt preload control.<br \/>\n2. Standard configuration supports simultaneous operation of two hydraulic torque wrenches; an optional configuration is available for simultaneous operation of four hydraulic torque wrenches.<br \/>\n3. The pump body is manufactured from aluminum-titanium alloy, providing a lightweight structure for convenient transportation and on-site operation.<br \/>\n4. Output pressure can be freely adjusted within the range of 40\u2013700 bar. A high-performance cooling system automatically activates the fan when the oil temperature reaches approximately 35\u00b0C, supporting long-duration continuous operation.<br \/>\n5. Equipped with a high-power brushless motor for reduced maintenance and extended service life. The motor incorporates a starting capacitor, allowing reliable starting under load and simplifying operation.<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 Features 1.
