  Range of activity  
      Its main assortment groups include:

  gear pumps - used in domestic and foreign tractors, combine harvesters, bucket loaders, fork lift trucks, vans as well as in machine building industry - mainly in machine tools


  hydraulic selector valves (distributors) with manual and electrical control, used in domestic and foreign tractors, bucket loaders, transportation means, building machines


  engine oil pumps,


  pressure relief and non-return valves - used in fork lift trucks, building and road construction machines, combine harvesters and steering blocks


   besides the company produces hydraulic power packs, piston pins, gear and piston flowmeters.

   HYDROTOR S.A. also offers repairs of gear and piston pumps, selector valves, servomechanisms, forcing elements of injection pumps. Thanks to its high accuracy equipment, the company started production of precision tools which are offered on foreign markets

   The company's activity also includes an innovative design, often unique on the world scale. Multi-piston pump of constant and variable delivery is the best example of such an innovation, it was elaborated with collaboration of Gdañsk Technical University and obtained its patent in the International Patent Office

  
  Production engineering characteristics  
   
       High precision stock of machine tools allows the company to machine elements of small and medium overall dimensions. See company's production capacity.
