Machine overview
Application and operating principle
The LU-FSMP8 is intended for high-volume production of narrow liquid sachets. Eight dosing lanes operate in parallel, increasing output without multiplying the number of standalone machines.
Well suited to
- High-volume liquid condiment lines
- Narrow sample sachets
- Products suited to controlled magnetic-pump dosing
- Manufacturers seeking high output per square metre

Configure the line
Common options and engineering decisions
- Lane count and sachet width review
- Product tank and recirculation configuration
- Coding, vision and reject integration
- Downstream counting, collating or cartoning
Performance validation
Confirm with product and film trials
Target output and dose repeatability are affected by product flow, environmental conditions, sachet length, film sealing window, changeover and quality-control settings. Supply representative product and production film for a meaningful test.
Any stated speed, range or accuracy is an indicative reference rather than a universal guarantee. Contract acceptance criteria should be documented for the final configuration.

LU-FSMP8 questions
Is the quoted speed the total machine speed?
No. The reference figure is per lane. Actual total output depends on active lanes, sachet length, film, product behaviour and quality-control requirements.
When are magnetic pumps suitable?
They are commonly considered for low-viscosity, compatible liquids. Product chemistry, viscosity, foaming and cleanability must be assessed before selection.
Can different products run in separate lanes?
Multi-product operation may be technically possible but introduces product-feed, cleaning, control and validation complexity. It should be defined as a bespoke engineering requirement.
Your next step. Send a representative product sample, target dose, sachet drawing, film specification and required output. Lancing Ltd will confirm the practical machine configuration, trial plan and acceptance criteria for your application. See related machine information.

Production specification for LU-FSMP8
Verify every liquid lane, not only the combined output
The eight-lane configuration is intended for narrow liquid sachets, so lane pitch, film registration, pump compatibility and lane-to-lane dose control are central. The quoted per-lane reference should be converted into accepted total output under an agreed test.
Project questions to answer before final specification
- Is the liquid compatible with magnetic-pump dosing at the required temperature and does it contain particles, air or ingredients that settle?
- What dose and tolerance applies to each lane, and how will samples remain traceable to their source channel?
- Does the finished width fit the reference lane format and approved web drawing, including the back seal, rounded corners and cut allowance?
- Will the machine produce individual sachets, perforated strips or another outlet arrangement, and how will those packs be collected or cartoned?
- How will the product tank and manifold maintain equal supply while the line is refilled and operated over a full production period?
Product distribution and registration must remain stable across the web
Independent dosing channels allow each lane to be adjusted, but a common supply system can still create unequal conditions if level, pressure or product composition changes. Sampling should identify every lane and should include periods after refill and stop-start events.
The total film width, lane pitch, print repeat, eye marks, back-seal position and cross cut form one artwork specification. Production film should be used to verify that the photocell and correction system hold the cut and seal in the accepted position across the entire web.
| Lane dose study | Take labelled samples from every lane at start-up, stable running, after refill and after normal adjustments. Report individual and lane-average results. |
|---|---|
| Web registration | Check print-to-seal and print-to-cut position across all lanes using production-representative registered film. |
| Seal and leak checks | Inspect longitudinal and cross seals lane by lane and apply the agreed pack-integrity test to a defined sample. |
| Product supply | Run the intended tank, hopper, manifold and refill method and observe whether product condition remains uniform across channels. |
| Accepted output | Count saleable packs and record lane-specific rejects, isolated lanes, normal inspections and downstream handling limits. |
When a single-lane or different dosing route may be better
Lower output, frequent format changes, highly viscous products or liquids with particles may favour a single-lane piston machine or another pump technology. A multi-lane layout should be justified by sustained accepted output and manageable cleaning rather than by headline speed alone.
Record the configuration that produced the result
A useful trial record identifies the product and film batches, dose setting, sachet dimensions, forming and sealing parts, coding setup, operating speed, stops, rejected packs and quality checks. Retained samples should be labelled so results can be traced to the lane, recipe or test condition where relevant.
The final quotation and acceptance schedule should distinguish indicative catalogue references from the values that will be demonstrated with the agreed product, pack and utilities.
Additional buyer questions
LU-FSMP8 project questions
How should eight-lane accuracy be reported?
Report each lane separately as well as the overall result. A combined average can hide a channel that remains consistently high or low.
Can the LU-FSMP8 run a different number of lanes?
The lane count is tied to dosing channels, forming, sealing, web layout and cutting. Any alternative configuration must be engineered and quoted rather than assumed.
What happens if one pump or lane is outside tolerance?
The required machine response, alarm, isolation or reject method should be agreed in the controls and acceptance specification before manufacture.
Why is the film drawing important?
The drawing coordinates lane pitch, print repeat, back seals, cross seals, corners, tear features and cuts. It should be approved by the machine supplier, film converter and pack owner.
Define the project around your product and pack
Send the application data needed to assess the LU-FSMP8
Provide representative product, every required dose and sachet size, film details, accepted output, utilities, cleaning and inspection requirements. Lancing Ltd can then confirm whether the LU-FSMP8 is the correct starting point and define the trial scope.
Model-specific lane assurance
Prove LU-FSMP8 liquid distribution, registration and seal integrity lane by lane
A combined output figure cannot show whether one dosing channel, nozzle or web position is weak. Preserve lane identity through the complete trial.
| Product distribution | Use the intended tank, hopper, manifold, refill and temperature conditions; record changes at start-up, refill, pause and restart. |
|---|---|
| Lane dose | Label and measure every lane at agreed intervals. Report individual results and the acceptance response to a weak lane. |
| Registration and code | Check print-to-seal, print-to-cut and variable-code position across the web using production-intent printed film. |
| Seal and integrity | Inspect longitudinal and transverse seals for product carry-over and apply the agreed method to lane-identified samples. |
| Accepted output | Count saleable packs while recording active lanes, rejects, normal inspection, product refill and downstream constraints. |
