What Pigging Is & How It Works
Pigging pushes the product left in your pipelines to its destination – so instead of being rinsed away, you keep it, pack it, and sell it.
Manufacturers use pigging to increase yield, reduce waste, minimize water use and speed up production changeovers for greater overall efficiency.
How Pigging Works (Quick Explanation)
A pigging system uses a specialist projectile (called the “pig”) which is slightly larger than the pipeline. The pig is introduced into the line and pushed through using pressure.
As it travels, it clears the pipe and recovers the remaining product. Pigs are inserted, housed, and returned via pig launchers and receivers, and the recovered liquid is collected or continues through processing.

Where Pigging Is Used
Pigging is used wherever liquids are processed:
- Chocolate & confectionery

- Sauces, dressings & condiments
- Soft drinks & beverages
- Personal care & cosmetics
- Homecare liquids
- Paints, coatings & chemicals
- Pet food & wet mixes
If you pump it, you can pig it.
How HPS Pigging Transformed DCS Manufacturing
A major personal care manufacturer switched from IBCs to large holding tanks and installed eight HPS pigging systems. The result:
- 93% reduction in waste
- 83% faster washout times
- Sanitisation time cut from 2–3 hours to ~15 minutes
- Minimal effluent and labour required
- Fast, reliable, fully automated changeovers
Pigging enabled higher throughput, improved product quality, and major efficiency gains across multiple production lines.
