Technology

ARMAK Geared Piston Motors - a new and superior technology - contact free running - long operating life - reliable and lowest maintenance

Applications and Advantages

ARMAK Geared Piston Motors  were designed for Applications

  • in Pneumatic Engineering, for example as winch drives, in conveyor systems, ship building, mining, off-shore applications, in general engineering or wherever high safety (explosion harzards) are required together with simple control and easy installation.
  • in Renewable Energies, to convert available heat sources into electric current. Applications reach from biogas plants or combined heat and power plants to sun mirrors or sun collector systems.

ARMAK Geared Piston Motors were initially designed as air motors and can be supplied in the range from 2 - 16 kW.

The basic design principle was kept, and the motors are now supplied also as gas pressure motors to run on non corrosive media with temperatures up to 150 °C and pressures up to 15 bar.

All versions do have these technical details and advantages:

  • non vibrating even at high speeds
  • frictionless torque producing motor parts resulting in long and maintenance free lifetime
  • completely enclosed motor casing - therefore as air motor no internal corrosion and no internal oil sump
  • compact design and freedom of installation
  • large usable speed range and high start torque
  • metric flange and shaft for mounting of gear boxes
  • for air motors perfect control with ARMAK lever / remote control valves

On the Air Motors the torque is developed by one rotating piston and is transferred to the output shaft with a synchronising gear train. Both rotating piston and sealing rotor are turning without physical contact and with an extremely small air gap for high motor efficiency.

On Gas Pressure Motors and Water Motors the rotating piston shaft is the output shaft.

This frictionless operation results in long maintenance free operation without downtime. The totally closed motor housing without breather holes permits applications in wet or dirty surroundings without danger of corrosion in the motor and it is leak proof.

ARMAK Geared Piston Motors are designed for difficult, critical applications.
