GWPS Series Pistol-Grip Cordless Hydraulic Pulse Wrench | Brushless Rechargeable Industrial Torque Pulse Fastening Tool
The GWPS series pistol-grip cordless hydraulic pulse wrench combines hydraulic drive and electronic control technology, serving as an industrial-grade fastening tool designed for high-precision torque control scenarios. It delivers impact-free, low-vibration torque output via hydraulic pulse technology. With electronic preset torque values, it achieves approximately ±5% control accuracy and automatically cuts power when the preset value is reached, effectively preventing workpiece damage from over-tightening.
Equipped with a high-performance brushless motor, advanced power shut-off system, LED indicator, non-contact switch, touch-control forward/reverse and sliding interface, it ensures convenient and efficient operation. Powered by 20V/36V high-capacity lithium-ion batteries for cordless and flexible operation, it is widely used for bolt fastening in automotive manufacturing, wind power equipment, bridge steel structures and other fields.

Hydraulic Pulse Torque Technology for Precise Control & Workpiece Protection
It delivers torque via hydraulic pulse technology with smooth, vibration-free and impact-free operation, freeing operators from reaction force and effectively reducing labor intensity. Built-in sensors and CPU dynamically monitor torque and automatically shut off power at the preset value with approximately ±5% accuracy. It prevents over-tightening, thread stripping and workpiece damage, ensuring consistent quality in batch assembly.
Brushless Motor + Power Shut-Off System for Efficiency, Stability & Durability
Powered by an advanced brushless motor, it delivers strong power with no carbon brush wear, long service life and nearly zero daily maintenance. Paired with a stable power shut-off system, it cuts power precisely when torque reaches the set value with fast response. Replacing the vane rotary drive of traditional pneumatic wrenches, it features lower energy consumption and less noise, suitable for long continuous operation in industrial sites.
Cordless Lithium-Ion Power for Flexible Operation Deployment
Powered by a 20V/36V lithium-ion battery platform, it completely eliminates constraints from air hoses and power cords, enabling flexible deployment for outdoor work, high-altitude operation and mobile maintenance. Two battery capacities, 2.5Ah and 5.0Ah, are available to match different operation durations and adapt to multi-scenario cordless work.
User-Friendly Industrial Design for Convenient & Efficient Operation
It features an LED work indicator for intuitive status display. The non-contact switch and touch-control forward/reverse design deliver sensitive operation response. The sliding battery interface enables quick and smooth battery installation and removal. The pistol-grip ergonomic handle fits the palm naturally for comfortable grip and force application, reducing fatigue during long operation.
Full Multi-Spec Coverage for Multi-Industry Scenarios
The full series covers a wide torque range of 7 to 90 Nm, with multiple drive options including 1/4"hex, 3/8" square and 1/2" square drives, compatible with various bolt and socket sizes. It is widely suitable for high-precision bolt fastening in automotive manufacturing, wind power installation, bridge steel structures, heavy machinery assembly and other fields.
