HST-EYP / HST-EYPS

Oil pulse tools for industrial applications

  • 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 oil replacement (without vacuum pump system)
  • Simple torque adjustment
  • Less reaction force to the operator´s wrist, arm and shoulder
  • Pricewise an interesting alternative

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 piston.

When the supplied air pressure goes down, the rotation of the air motor slows down and simultaneously, the number of pulses being generated becomes lower, also. As a result it takes more time to build up enough fluid pressure to activate the shut-off piston which will transmid fluid force to the air shut-off valve by way of the signal pin located in the center of the rotor.


This automatic self-controlled mechanism is called „DIRECT AIR SHUT-OFF“, and it is patented.

Illustration on the top shows how stable shut-off torque can be maintained even if the supplied air pressure fluctuates between 4 bar and 6 bar.

DIRECT AIR SHUT-OFF, patented, makes it possible for HST-EYP pulse tools to provide most accurate and stable shut-o 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 adopted as ordinary O-ring.  
     
Diesel engine oil, popularly available in the market, used for HST-EYP pulse tool enables less expensive oil replacement cost.  
     
Changeable driving end of HST-EYP pulse tools, patented, enables less reserve cost of backup tools.  
   
Simplified method of oil replacement available for HST-EYP pulse tool enables quick oil change service without using vacuum pump system.  
   
Easy change positioning of relief valve, located in the center of HST-EYP pulse tool, enables less time period for adjustment to meet target torque.        
Less reaction force from HST-EYP pulse tool combined with ergonomic grip handle provides operator friendly handling and less fatigue to the operator´s wrist, arm and shoulder.    
   
Declared values of HST-EYP pulse tools regarding noise level and vibration meet harmonized standards specified in compliance with
CE Declaration of Conformity.
   
   
Competetive tool pricing of HST-EYP pulse tools enables to save customer´s investment cost.
