Schmalz - The Company The distributor has to match the used hose diameter and the

number of suction cups.

Vacuum Knowledge Example:
The hose VSL 8/6 has an outside diameter of 8 mm and an internal
diameter of 6 mm. Six suction cups are used.

For this example we choose:
Plug-in screw unions STV-GE G1/4-AG 8 for the hose VSL 8/6
Vacuum Suction Cups with outside diameter 8 mm and internal diameter 6 mm as well
as 1/4" thread matching the female thread of the distributor.

Plug-in screw union STV-GE G3/8-AG 8 fits the spring plunger.
Special Grippers Distributor VTR G3/8-IG 9xG1/4 with one input (3/8" thread)
and nine outputs (1/4" thread).
Vacuum Grip- ping Systems Three sealing screws VRS-SB G1/4-AG to close the three open outputs.

Mounting Elements Vacuum Generator Selection

Vacuum Generators The selection of the matching vacuum generator (ejector, pump
or blower) is determined by several factors:
• Type of workpieces:
porous, air-tight
• Energy supply options: a lower case electricity,
compressed air
• Restrictions for size and weight
Valve Technology • Maintaining cycle times Ejector
short cycle times:
Long transport distances: Pump or blower
Switches and Monitoring

Filters and Connections For this example we choose:

Ejector to generate vacuum.
Because the workpiece in this case is air-tight, you can create a simple and lightweight structure while implementing short pick-up and
release times.
