Pulse Tool | PTX Pulse Tool

In ErgoPulse shut-off tools the air supply is shut off as soon as the pre-set torque has been reached, minimizing operator infl uence. The result is increased accuracy and faster tightening.

Torque sensing system: In ErgoPulse PTS and PTX nutrunners torque is “sensed” by means of a rotatable inertial mass acting against an adjustable spring. The result is a highly accurate and easily adjustable shut-off system.

Pulse mechanism: The pulse mechanism has pistons for minimum weight and long service life. The design is based on cam-guided pistons and rollers and the pulse cylinder is oil-filled. The moving parts are thus completely immersed in oil, which ensures a long service life.

Twin chamber vane motor: This is designed to give high torque at low speed, which gives the best characteristics for fast, accurate tightening.

TRIM valve: A patented adjustable valve at the air outlet is used to maximize tool accuracy on one type of joint, which could be hard, medium or soft.
