ATEX certified OMS, OMT and OMV

Danfoss logo

Hydraulic Orbital Motors are designed for mobile and stationary applications. Some motors are used in related applications, where locations are classified as hazardous areas. The ATEX Directive 2014/34/EU specifies the minimum safety requirements for equipment intended for use in potentially explosive atmospheres in European Union member states.

ATEX is derived from the French term “ATmosphères EXplosives”. The equipment intended for use in hazardous areas are divided into two groups: Group I: Equipment intended for use in underground parts of mines (mining equipment). Group II: Equipment intended for use in other places than mines (non-mining equipment).

The Danfoss hydraulic orbital motors are intended for use in Group II applications.

T-series, for tough applications

With pressure capability up to 350 bar [5,080 psi] and high starting torque, the T-series is the energy-efficient choice for the toughest working environments. Leading performance with a long lifetime makes light work of the heaviest duties. Up against high pressures, thin oil or frequent reversals, our motors are guaranteed to perform smoothly and efficiently - even at low speed.

T-series characteristics

  • Motors with speed sensor
  • Ultra short motors 
  • Motors with integrated brake 
  • Motors with integrated flushing valve 
  • Special dust seal ring for additional shaft seal protection

Features and benefits

  • High bearing capacity and robust cardan shaft design for longer life 
  • Outstanding motor efficiency for reduced fuel consumption 
  • Low leakage, securing energy savings 
  • Short motors without bearings for compact integration in gear boxes and other flexible design options 
  • Integrated flushing valve for continuous oil renewal and cooling in a closed circuit 
  • Special mounting flange on wheel motors for optimal utilization of bearing capacity 

Product range

Our large orbital motors are an excellent choice for the propel and work functions on many applications – including skid steer loaders, trench compactors, forestry harvester heads, and beet harvesters.
