What to Know When Buying a Used Liquid Filling Machine
What to Consider When Buying a Used Liquid Filling Machine
Learn about product compatibility, CE risks, and technical issues to consider
when purchasing second-hand liquid filling machines.
Many manufacturers and entrepreneurs aiming to establish high-quality filling systems
initially turn to used liquid filling machines.
Although second-hand machines may reduce initial investment costs,
they can pose serious technical risks if not properly inspected.
In this article, we share common problems found in used filling machines,
key points to check before purchasing, and the right solution approaches.
Why Are Used Liquid Filling Machines Preferred?
- Lower initial investment costs
- Short-term production targets
- Creating backup production lines
- Cost-effective solutions for trial production
However, uninspected machines may lead to high failure rates
and quality issues over time.
Most Common Risks and Failures
Filling accuracy issues:
Malfunctions in piston or flowmeter systems cause volume deviations and product losses.

Nozzle leakage and dripping:
Worn seals and nozzles result in leakage and product waste.
Worn seals and nozzles result in leakage and product waste.
PLC and electronic failures:
Older machines may suffer from PLC, HMI, or sensor malfunctions, with spare parts being costly or difficult to source.

Calibration and torque problems:
Incorrect servo motor or torque settings cause issues in downstream processes.
Incorrect servo motor or torque settings cause issues in downstream processes.
What to Check Before Buying a Used Machine
- Observe filling tests on-site
- Inspect nozzles, pistons, and seals
- Review the electrical panel and PLC software
- Confirm which products were previously filled
- Check the frame and body for corrosion or cracks
- Verify spare parts availability and service support
Difference Between Refurbished and Used Machines
Used machine:
Purchased as-is from the previous owner, often without testing.

Refurbished Liquid Filling Machines by Midas Makina
Midas Makina offers demo or short-term used machines as
refurbished and guaranteed solutions.
- Mechanical components renewed
- PLC software updated
- New nozzle and seal assemblies installed
- Faulty components replaced with original spare parts
- Performance-tested and delivered with reports
This allows you to start production with a lower budget
while ensuring a reliable system.
Conclusion
Buying a used liquid filling machine can be a smart investment
when done correctly. However, insufficient inspection may result in
production downtime, product losses, and high maintenance costs.
Working with an experienced manufacturer provides technical reliability
and long-term operational confidence.
