The Specken-Drumag Group is specialized in the production of pneumatic and hydropneumatic drive systems as well as products for generation, distribution and and processing of compressed air. The company has been in existence for more than 100 years, is operating worldwide and has a long and eventful history in pneumatics and hypopneumatics.

Specken-Drumag attaches particular importance to customer proximity and innovative thinking. While the former contributes to customer satisfaction, the latter ensures original, tailor-made solutions for a wide range of applications and industries. A harmonious interaction between man and technology is also important to the company. This is made possible in the company’s own state-of-the-art design, laboratory and customer service facilities. Here, flexible systems for fluid technology are developed and realized. The customer service of Specken-Drumag is well developed and is available to existing and interested customers for advice and help in selecting the right products.

While compressed air technology has the advantage of achieving a high working speed due to the rapid availability of energy, the stiffness of the hydro flow in hydraulics provides good controllability. Hydropneumatics as hybrid technology combines both advantages and often results in better solutions in the field of linear or rotary drives, which would not be possible by using conventional pneumatics or hydraulics alone. These include successes such as the infinitely variable stick-slip-free creep speeds as well as combinations of rapid and creep speed. In addition, Specken-Drumag’s products achieve in this way constant motion sequences, which are possible due to the control of tensile and compressive loads, and good results in positioning and locking against external forces.

The speedPOWER high force cylinder from Specken-Drumag represents the new generation of power cylinders for press and machine construction. Compared to an identical pneumatic cylinder, the cylinder develops many times more force in the power stroke – and all this with the same air consumption.

Further products from the field of hydropneumatics are:

  • Hydropneumatic drives HPZL, HPL, P40
  • Hydropneumatic locking cylinders
  • Hydropneumatic pressure intensifiers and pressure medium converters
  • Pneumatic drive with adjustable stroke length
  • Hydropneumatic cylinder with attached pressure intensifier
  • Hydropneumatic cylinders


Specken-Drumag’s product portfolio in the hydraulics sector includes an extensive range of different hydraulic cylinders as well as pneumatically operated, hydraulic compact power packs. These offer decisive advantages, for example they improve energy efficiency.

Customer-specific designs in hydraulics are possible in the area of hydraulic and clamping cylinders. In addition, Specken-Drumag offers a pneumatic compact hydraulic power pack as an alternative to the usual hydraulic power packs. This scores in comparison with a particularly high power density, a maximum pressure of up to 350 bar and a short-term volume flow of up to 100 liters per minute. In addition, it consumes no energy when not in use and is virtually silent.

Proportional technique

Proportional technology ensures that work processes adapt quickly and very precisely to changing requirements. For example, proportional pressure regulators, positioners and flow regulators provide position control for rotary and linear actuators, exactly as the customer needs it.

Of course, there are also customer-specific special solutions in this area, for example, hydropneumatic high-pressure control systems for rotary actuators with customer-specific designs.

Electric cylinder

An exemplary product from Specken-Drumag in the field of electric cylinders is the RCP, an electric cylinder with a battery-free absolute encoder. This encoder is an innovative, patented measuring device. The particular advantage is that the costs and effort of changing the battery and the associated settings are eliminated. Instead of a battery, a series of gears takes over the detection of the rotational position data. In this way, no battery is required, which was previously part of every conventional absolute encoder.

Pressure and vacuum

Oil-free compressed air is needed wherever oil could interfere. This is the case, for example, in places where the oil could falsify measurement results or where health aspects play a role, such as in the medical sector or in the food processing industry. Specken-Drumag offers the following products in the field of pressure and vacuum

  • Compressors and vacuum pumps
  • Dryer
  • Decentralized compressed air generation and treatment systems

Drive technology, electronics, fuel cell systems

In the field of electronic drive technology, Specken-Drumag manufactures speed controllers, power supplies and customer-specific solutions. The company also develops electric motors and gear motors for DC technology. In close cooperation with the customer, special assembly group production is also possible in the following areas:

  • SMT assembly
  • THT assembly
  • System and component manufacturing including electrical function test and EMC
  • Device safety
