Three Stage Electric Torque Wrench Pump

A 3-stage flow hydraulic wrench pump offers three distinct pressure/flow output settings. This allows operators to start tightening bolts rapidly at high flow/low pressure, then switch to medium flow as resistance increases, and finally deliver maximum torque at high pressure/low flow for final tightening and precise positioning. This staged approach significantly improves efficiency compared to single-stage pumps. It’s ideal for applications requiring both speed during the initial run-down phase and high, controlled torque for final bolting accuracy.
