Self-regulating Vacuum Pumps (electric vacuum and blow-off control), GVMAX E1 series
The Coval GVMAX E1 series is an array of self-regulating vacuum pumps that are ideal for handling air-tight objects and for medium- or long-cycles. These pumps integrate an electric vacuum and blow-off control that enables regulation of compressed air consumption. Furthermore, the E1 series is offered in 7 variants with a uniform weight of 510g.
. Nozzle Ø : 2.5 mm
. 3 levels of vacuum : 50% - 75% - 90%
. Suction flow rate : up to 360 Nl/min
. Vacuum regulation function
When the selected vacuum level is reached, the compressed air supply stops. This interruption does not have any effect as the non-return valve maintains the vacuum and thus the grip. The vacuum switch continually analyzes the vacuum requirements. As soon as the minimum threshold is reached, it activates the vacuum generation valve to return to the pre-set value.
The GVMAX E1 has a non-return valve installed as standard which enables it to maintain the vacuum within the circuit if there is a power failure. This function guarantees maximum safety conditions for operators during handling.
