Selection checks
A paste filler is only right when it handles the real product.
The same machine may perform differently with a cold gel, warm sauce, sticky honey or stringy adhesive. Use these checks to send the details needed for a more accurate machine recommendation.
Product behaviourViscosity, temperature, particulates, aeration, stringing, settling and whether the product changes during the day.
Fill requirementTarget fill volume, tolerance, dose range, container neck opening, headspace and whether the fill is by volume, level or weight.
Container and closureJar, bottle, tub, cartridge, pail or jerrycan dimensions, cap style, labelling area and pack stability on conveyors.
Production targetRequired bottles per minute or per hour, number of SKUs, changeover frequency, cleaning process and operator involvement.

Industrial paste filling →Are paste filling machines different from liquid fillers?
Paste fillers are specified for products that do not flow like water-thin liquids. The equipment, hopper feed, pump or piston route, nozzle style and cut-off arrangement must suit the viscosity and container.
Can one paste filler run several products?
Often yes, but it depends on viscosity range, fill volume range, cleaning time, product contact parts, hopper design, nozzle size and changeover frequency.
What information is needed for a paste filling machine quote?
Provide product details, fill volume, container dimensions, closure, target output, cleaning needs, available air or power, and whether capping or labelling must be integrated.
Machine selection evidence
Compare published reference configurations without treating them as universal limits.
Lancing publishes several piston and pump-based configurations across its specialist machinery sites. They are useful reference points, but the final fill range, accuracy and output must be confirmed against the actual product, container and production conditions.
| Published Lancing reference | Verified configuration detail | How to use the figure |
|---|---|---|
| Automatic paste filler | Six filling nozzles; piston modules listed as 5–100, 10–300, 50–500, 100–1000, 500–3000 and 1000–5000 ml; reference accuracy listed as ≤±1%. | Use only as a starting configuration. Accuracy must be checked at the required dose with the real product, product temperature and container. |
| Semi-automatic paste filler | Pneumatic twin-head piston format with cylinder modules listed from 10–100 ml through to 1000–5000 ml. | Confirm the chosen cylinder covers every required SKU without forcing one module to work at an unsuitable extreme. |
| Rotor-lobe filling route | Published 5–5000 ml range, multi-nozzle options, stainless construction and options for heated or jacketed product paths. | Confirm particle passage, shear, cleaning method and dose control by trial. Pump range does not by itself define achievable output. |
Accuracy needs test conditions
An accuracy percentage is incomplete unless the test states the product, dose, density or weight conversion, product temperature, number of samples, machine speed, container and measurement method. For regulated net contents, agree the buyer’s own quality and legal-metrology requirements rather than relying on a generic catalogue statement.
Output needs the whole cycle
Output depends on product refill time, piston or pump stroke, nozzle opening, container indexing, head count and downstream capacity. A meaningful result is a timed run that includes stable product supply and repeated containers, not a single fastest cycle.
Particles need a passage review
Record the largest particle, typical particle concentration and whether pieces must remain intact. Valve ports, pipework, pump clearances and nozzle bore should all be reviewed. A product may be pumpable yet still block or damage at the final nozzle.
Cleaning needs a product-path map
List every wetted part from hopper or feed pump to the nozzle. Decide what can be cleaned in place, what must be removed, how residual product is recovered and how the machine will be verified clean before the next batch.
Shortlist route
Move from a headline machine type to a testable specification.
Use the product sample, dose range and pack geometry to narrow the route before comparing price. This reduces the risk of buying a machine with the right headline range but the wrong valve, nozzle or cleaning arrangement.
1. Confirm product condition
Record temperature, viscosity behaviour, particles, aeration, settling and any sensitivity to shear or pressure.
Review viscous-product behaviour →2. Confirm dosing route
Compare piston, rotor-lobe and other positive-displacement methods against the real product path and changeover needs.
Compare dosing technologies →3. Confirm acceptance
Agree sample count, fill measurement, clean cut-off, output and cleaning demonstrations before the equipment is signed off.
Plan the test protocol →Machine FAQs
Questions to settle before selecting a paste filler.
Does the largest stated fill range mean one cylinder covers every volume?
No. Published ranges normally use different cylinder or dosing modules. The selected module should be matched to the actual minimum and maximum fills and confirmed during a representative trial.
Can one filler handle food, cosmetics and adhesives?
The dosing principle may be similar, but wetted materials, seals, cleaning, hygiene, curing risk and product recovery can be very different. Compatibility and changeover must be reviewed for each product family.
Should accuracy be checked by volume or weight?
The test method should match the buyer’s quality requirement. Weight checks are often practical, but density and temperature must be considered when a volumetric dose is being assessed by mass.
What sample quantity is needed for a useful trial?
Enough product is needed to prime the hopper, pump, hoses and nozzles, adjust settings and run repeated fills. The exact quantity depends on the machine path and should be agreed before the test.
When should capping and labelling be included in the filler specification?
Include them at the start when container stability, product on the neck, cap presentation or label application could limit the line. A filler should not be specified in isolation if downstream handling sets the true production rate.
Route elimination
Use the difficult product behaviour to eliminate unsuitable filling routes.
The best shortlist starts with the worst credible production condition. A machine that fills the easiest sample may still fail when the hopper is low, the batch is colder, particles concentrate or the interval between containers increases.
| Observed behaviour | Engineering focus | Evidence to obtain |
|---|---|---|
| Slow or incomplete chamber refill | Hopper outlet, inlet valve, product head, transfer pressure and refill time. | Observation of consecutive draw strokes at the lowest normal hopper level and thickest normal product condition. |
| Particles separate, bridge or become damaged | Valve passage, pump clearance, hose and nozzle bore, agitation and residence time. | The largest credible particles at normal concentration, inspected before and after filling and across a sequence of containers. |
| Tails, strings or product on the neck | Shut-off point, suck-back, nozzle diameter, fill profile, product pressure and container movement. | Close-up video at normal temperature and the intended interval between containers, including stop-and-restart behaviour. |
| Texture changes after pumping | Shear, recirculation, pump speed, restrictions and repeated passes through the product path. | A retained unfilled sample compared with product collected after a realistic run, not only after the first fill. |
| Viscosity changes with temperature or time | Hopper heating, pipe or hose heat loss, agitation, batch hold time and startup sequence. | Product temperature and fill results at the beginning, middle and end of the operating window. |
| Product is abrasive, reactive or difficult to recover | Wetted materials, seals, cavities, dwell time, shutdown cleaning and spare product-path parts. | Written compatibility review, maximum permitted dwell time and a witnessed emptying, strip-down and restart sequence. |
Multi-SKU planning
Define a product family before asking one filler to cover every SKU.
A broad model range does not mean that every product and pack can share the same cylinder, valve, nozzle, seals or cleaning method. Grouping SKUs by the changes they require gives a more realistic machine and change-part specification.
Common dosing path
Products can share a route where the selected piston or pump, valve passage, seals, hose diameter and nozzle can handle them without contamination, damage or excessive hold-up. Separate paths may be sensible for incompatible, reactive or strongly flavoured products.
Common dose and pack family
Group fills that use a practical cylinder or pump setting and containers that can share guides, nozzle height and indexing. A small-dose jar and a large pail may need different modules or even a different filling principle.
Common cleaning and product condition
Products that need different temperatures, agitation, cleaning agents or verified changeover procedures should not be treated as one easy recipe change. Record the physical parts and operating checks required for each family.
This domain should remain focused on paste and viscous-product behaviour. Use Liquid Fillers for broader free-flowing and foaming liquids, Volumetric Fillers for general volumetric dosing, Chemical Fillers where chemical compatibility or hazardous-product requirements lead the specification, Automatic Filling Machines for wider automatic-line ownership, and Bottle Filling Machines where the main intent is container-led rather than paste-led.
Shortlist questions
Questions that prevent an over-broad machine specification.
Why should the worst normal batch be used for selection?
It exposes refill, particle passage, cut-off and temperature problems that may not appear with a warm, smooth or freshly mixed sample. The worst credible batch should still be normal saleable product, not an artificial extreme.
What is a useful product family for one paste filler?
It is a group of SKUs that can use the same basic wetted path and operating method with defined changes such as settings, cylinder module, nozzle or container guides. The grouping should be based on engineering changes, not only marketing names.
When should separate hose or nozzle sets be considered?
Consider them where flavour, colour, chemistry, cure risk, cleaning validation or turnaround time makes a shared path difficult. The quotation should identify which parts are dedicated and how they are stored and verified.
How should two suppliers be compared fairly?
Give both the same product and pack information, require the same trial conditions and compare accepted output, dose evidence, cut-off, product recovery, cleaning, change parts, exclusions and downstream scope rather than head count alone.
Engineering verification
Compare machine routes against one written test case.
A fair comparison uses the same product batch, temperature, dose, pack, measurement method and accepted-output definition for every candidate technology.
| Decision | Evidence to request | Reason |
|---|---|---|
| Dosing method | Sequential results at the lowest and highest required fill with the real product. | Shows refill stability, head-to-head variation and whether the selected displacement range is practical. |
| Product path | Valve, hose, pump or cylinder and nozzle arrangement, plus a representative product trial. | Exposes restrictions, particle damage, aeration, heating and cleaning access. |
| Automation level | Accepted packs per hour including loading, indexing, capping, labelling and minor stops. | Prevents a fast dosing stroke being mistaken for sustainable line output. |
| Lifecycle fit | Change parts, cleaning sequence, maintenance access, spares and future formats. | Determines whether the machine remains practical after the first product is launched. |
Use the technical resource centre to prepare a specification, sample trial, FAT and commissioning plan.
Machine-selection questions
Questions that expose the real product-path requirement.
The name of the machine is less important than the conditions it must reproduce. These answers focus on the restrictions, feed method, pack presentation and product recovery that often decide whether a paste filler remains practical after the demonstration.
What is the first restriction to check in a paste filling system?
Check the smallest or most complex product passage that the real product must cross: an inlet valve, outlet valve, hose bend, pump clearance or nozzle. The largest normal particle, fibre or agglomerate must pass without blockage or unacceptable damage, and the surrounding paste must still refill the dosing path consistently.
How do I know whether hopper feed or pump feed is more suitable?
Hopper feed can be simple and easy to inspect when product can be loaded close to the filler and enters the dosing chamber reliably. Pump feed can reduce manual handling or connect a remote vessel, but introduces suction, pressure, control, hold-up and cleaning questions. Both routes should be compared with the real product and expected production pauses.
Can the same filler handle both jars and narrow-neck bottles?
It may, but the nozzle, fill position, container guides and fill profile can be different. A wide jar can accept a larger nozzle and shorter fill path, while a narrow-neck bottle may need tighter alignment, a smaller or diving nozzle and more control of tails and air. Treat the pack formats as separate trial conditions until proven.
Why does product recovery matter when choosing a filler?
Product left in a hopper, cylinder, pump, hose or manifold becomes waste, cleaning load or cross-contamination risk. On short batches, the value and volume of retained product can matter more than nominal cycle speed. Record start-up, normal running and end-of-batch recovery when comparing machine routes.
Compare hopper-fed and pump-fed paste filling, use the paste filling nozzle selection guide, and review product-waste reduction.
Need to shortlist a machine route?
Provide the product, pack, fill range, cleaning expectation and target accepted output so the shortlist can be based on the complete process rather than a machine label.
Published configuration comparison
Compare the machine structure before comparing headline output.
These Lancing reference configurations show how nozzle count, container movement and product feed change the application. Published figures remain conditional on the real product, fill volume, container and acceptance method.
| Configuration | Published structure | Published reference range | Decision to confirm |
|---|---|---|---|
| LU-GT1 | Single-nozzle pneumatic piston filler | 10–100 ml through 1000–5000 ml cylinder options; 5–20 bottles/min reference | Whether manual container placement and the selected cylinder/nozzle suit the product and batch size. |
| LU-GY1C | Single-head pneumatic filler with 2 m conveyor | 5–100 ml through 1000–5000 ml options; 10–20 bottles/min reference | Whether conveyor presentation, bottle detection and one filling head remove the current handling constraint. |
| LU-YTGt-4PX | Four piston heads, large hopper and transfer feed | 5–100 ml through 1000–5000 ml options; 20–50 bottles/min reference | Whether product supply, four-lane dosing, container indexing and downstream equipment can sustain accepted output. |
Do not treat a published accuracy figure as an application guarantee. Record the product temperature, fill target, sample sequence, measuring method, container handling and number of active heads when the configuration is tested.
