Oil pulse tools for industrial applications EYP series • 5 - 600 Nm • High torque repeatability • Less maintenance Pulse unit consists of significant less parts as tools of other manufacturers • Lower oil warming Thereby a significant higher service time and less oil changes (250.000 cycles) • Simplified method of oil replacement (without vacuum pump system) • Simple torque adjustment • Less reaction force to the operator´s wrist, arm and shoulder

1 Durable oil seal Sealing lower pressure oil 2 Simple Structure Presents maximum torque output - patented -3 Protector For the protection of the work piece 4 Direct air shut-off New mechanism - patented -5 Changeable driving end Multiple driving ends available - patented -6 Relief valve Easy to adjust range of torque 7 Ergonomical handle For a better handling of the tool

Torque shut-off precision also while supply air fluctuates The unique design of HST-EYP pulse tools, combining pulse unit and air shut-off mechanism, provides the most excellent accuracy of shut-off torque while supply air pressure fluctuates between 4 bar and 6 bar or more. While generating a pulse, some amount of high pressure oil is going through the internal oil passage (tunnel) in the wall of the anvil and flows into the oil chamber through the check valve orifice. During a series of pulses, the accumulated volume of oil in the chamber keeps increasing and finally activates the shut-off...

Advantages of the HST-EYP series Advantages DIRECT AIR SHUT-OFF, patented, makes it possible for HST-EYP pulse tools to provide most accurate and stable shut-off performance despite of possible fluctuation of supplied air pressure between 4 bar and 6 bar. Simple structure of HST-EYP pulse mechanism, patented, presents maximum torque output, most durable life time, less wearing parts, less overall maintenance cost, as well. Durable oil seal having two seal-points configuration can offer no oil leakage for a longer overall service life at less expensive replacement costs; same material...
