SKC203
描述
VMECA Smart Keyboard Pump is stackable vacuum generator. Each pump creates vacuum as an individual pump. The advantages of this unit is that it can be operated using just two control valve while retaining individual vacuum lines separate to one another, therefore if any leakage or surface deformation occurs and one pad loses it vacuum, it does not effect the vacuum level in the other pads. Pumps can be stacked up from 8 units depending upon requirements.
