Vacuum pumps with integrated pressure regulator, GEM series

Vacuum pumps with integrated pressure regulator, GEM series

The COVAL innovation intelligent vacuum pump series originates from Twintech technology. Twintech is an ‘all in one’ concept which for the first time integrates all the necessary components at the heart of the vacuum pump. Thus the user eliminates the need to order and assemble the individual components such as electro valves, pilots, vacuum switches, pressure regulators, filters etc. The modular aspect of the intelligent vacuum pumps also allows the user to choose only the functions needed for the application.

Vacuum pumps with integrated pressure regulator, GEM series


A Coval innovation, the GEM series vacuum pumps integrate TWINTECH™ technology. GEM series pumps provide an “all-in-one” solution by integrating all the necessary functions, such as pressure regulator, electro pilots, valves, vacuum switch, silencers in a single compact module. The M12 connector radically simplifies installation and use.

The GEM series pumps are available in:

  • 2 vacuum levels: 60% and 90%
  • 5 nozzle diameters (1,2 ; 1,5 ; 2,0 ; 2,5 et 3,0 mm).


The following specificities can be obtained on request:

  • Vacuum controlled by a NO solenoid pilot
    With a Normally Open solenoid pilot, the piece remains gripped even in the
    case of power failure.
    > safety measures for certain applications
  • Vacuum pump with automatic and timed blow-off
    > 1 single control signal.
  • Module with integrated vacuum gauge
    > visualisation of vacuum level.

Branch-specific applications


Traditional single or multi-stage vacuum pump must be equipped with additional peripheral modules necessary for it to function: solenoid-pilots, valve and electronic circuit, supply pressure regulator; vacuum switch, which penalize the size, weight, connections and the overall cost of the vacuum system. The COVAL TWINTECH allows integration of all these functions into a single compact lightweight module. The installation is radically simplified: no more peripheral components to be selected, ordered or installed. An immediate connection to circuits is possible thanks to the M12 connection. Optimal exploitation and minimal consumption of compressed air.
