Rotary vacuum packaging machines need stable vacuum and pneumatic control while the turret, sealing head, or pouch handling station rotates through each cycle.
Who this is for: Packaging machinery OEMs, vacuum system designers, and food equipment manufacturers building rotary vacuum packaging lines.
Vacuum packaging stations often combine vacuum extraction, positive air blow-off, clamp actuation, and sealing motion in one rotating machine area.
A multi-passage rotary union keeps these circuits separated so vacuum level, air actuation, and release timing remain consistent during rotation.
Typical requirementAir and vacuum rotary transfer for rotary packaging turrets, sealing heads, and pouch handling stations.Confirm target vacuum, leakage tolerance, and whether vacuum and pressure lines must be isolated.
Packaging machines usually run frequent cycles, so seal life and hose support should be reviewed.
Food or washdown areas may need special material and sealing confirmation before selection.
| Machine Area | Common Function | Selection Focus | Begapunk Direction |
|---|---|---|---|
| Rotary pouch machine | Vacuum extraction and clamp air | Passage separation and repeatable sealing | BP-2P or BP-3P |
| Vacuum sealing head | Vacuum plus release air | Low leakage and compact mounting | 2P air/vacuum rotary union |
| Rotary bag handling station | Suction cup vacuum and blow-off | Vacuum stability and port layout | BP-3P or custom design |
Send the machine layout, media, pressure, passage count, RPM, port size, and mounting space. Begapunk can review the interface and suggest a suitable standard or custom pneumatic rotary joint.
Yes. Vacuum applications are common, but leakage tolerance, seal structure, and port layout must be confirmed.
Yes, when separate passages are used and the rotary union is selected for the required pressure and vacuum level.
