LIAG / DMV Pigging Systems

Recover More Product. Reduce Waste. Improve Line Efficiency.

Convert product loss into saleable output by recovering valuable product trapped in pipelines.

Advanced Product Recovery Technology

LIAG / DMV hygienic pigging systems help factories recover
product trapped in pipelines after production runs.

Instead of flushing product to drain or pushing it out
with water, pigging uses a hygienic “pig” to push the remaining product
out of the line—maximizing yield and reducing waste.

For dairy, beverage, and food plants, pigging is often one of the
fastest-payback investments because it converts product loss into saleable output.

Payback Often < 1 Year

Rapid ROI through resource savings

Why Pigging?

Up to 99% product recovery from pipelines.

Major reduction in product loss and giveaway.

Less wastewater and lower COD load on treatment plants.

Reduced water use through decreased flushing and pre-rinse requirements.

Faster changeovers and improved line availability for more production uptime.

Rapid ROI with payback typically achieved within 12–24 months.

How a Pigging System Works
A seamless integration into hygienic production environments.
Insert
The pig sits in a launcher (docking station) at the beginning of the line.

Push

Compressed air or another safe driving medium pushes the pig through the pipe.
Recover
The pig pushes the remaining product to the receiving tank—turning “line hold-up” into saleable product.
Return & Repeat
The pig returns to its station, ready for the next production cycle.
Yield Recovery
Increases profitability by selling product that was previously wasted.
Operational Savings
Reduces costs related to cleaning chemicals, water, and wastewater treatment.
Efficiency
Minimizes dilution during rinsing and reduces downtime during transitions.
ROI Factors
Payback speed depends on product value, pipeline length, and changeover frequency.
