Energy savings in vacuum automation: pump instead of ejector.

With the GCPi compact pump, Schmalz presents a powerful vacuum generator with a purely electric suction and blow-off function. Complemented by the electric compact valve LQE, the user gets a compressed air-free vacuum system with the performance of conventional ejector solutions.

Wherever compressed air is not available and efficiency is key, all-electric vacuum systems are in demand. This can be in manufacturing and assembly, as well as within autonomous conveying systems and in robotic applications. Using an efficient double-head diaphragm pump, the new Compact-Pump GCPI generates the vacuum required for the task at hand. Instead of compressed air, it only needs a 24-volt power supply, for example from a battery. Thanks to the integrated energy-saving function, the speed of the pump is controlled as needed and optimized for the respective workpiece.

The GCPi is IoT-ready: process parameters are entered via the integrated IO-Link interface or via digital control signals. In addition, it is possible to enter parameters via the LCD touch screen linked to the device. The user reads out information about the process via the integrated NFC interface. The GCPi is equipped with additional connections that also allow operation of the new LQE compact valve: the all-electric 3/2-way valve can be mounted directly on the gripper. This significantly speeds up evacuation and ventilation of the vacuum system. A sensor integrated into the LQE that monitors the vacuum provides even greater process reliability. If independent zones are to be implemented in the vacuum system, several LQE compact valves are used for decentralized control. The vacuum for this is generated - centrally - by the GCPi.
