• Nozzle Diameter: Ø 2.5 mm
• Vacuum Maximum:85%
• Suction Flow: Up to 200 Nl/min
• Integrated Vacuum Regulator
• 2 Pneumatic Vacuum Switches
  
  
  

Communication between the pneumatic vacuum switch and the holding valve regulates and significantly reduces compressed air consumption.
This vacuum pump series is recommended for gripping and handling airtight products, as well as for medium- and long-cycle operations — and is particularly suitable for use in explosive environments.
The series also features a pneumatically controlled blow-off function.

Operating Principle

When the selected vacuum level is reached, the compressed air supply is shut off. This interruption does not affect operation, as the check valve maintains the vacuum and gripping action.
The vacuum switch continuously analyzes the system’s requirements. When the minimum threshold is exceeded, the vacuum generation valve is reactivated and the selected vacuum level is restored immediately.

Safety

GVMAX P1 series vacuum pumps are equipped with two integrated check valves as standard. This ensures that vacuum is maintained even if pneumatic power is lost, providing maximum operator safety during handling operations.
