Filling Machine Selection Guide

There are many different technologies and capacities of filling machines available on the world market. It is possible to fill many products on more than one type of filling machine. Choosing the best liquid filling machine for your application is a complex decision based on a host of factors including product characteristics, container characteristics, fill size, daily production needs, plant environment, regulatory issues and hardware cost versus performance.

Machine capacities range from the humble manual filler operating at 10 containers per minute (CPM) to high speed rotary systems operating at 1000+ CPM. Inline Filling Systems specializes in machines for companies producing up to 200 CPM as well as startup companies producing less than 1000 containers per day.

There are expensive liquid filling machine technologies beyond the reach of most small to medium sized bottling operations. There are also some very cheap machines, including Chinese and other foreign imports, that cost owners more to maintain and often result in production downtime or quality issues. After designing and building many different types of filler machines over a 20 year period and operating our fillers in our own contract packaging environment, we have the wisdom and experience to offer you only those technologies which provide the best versatility, flexibility and reliability for the best cost.

The machines we recommend are listed below with links to more information that will help you understand how to select the type and capacity filler you need for your operations.

overflow filling machine

Overflow Filling Machine

The most widely used filling machine in small bottle filling operations because it handles a wide range of liquids at a modicum of cost. Ease of cleaning, ease of setup and expandable output makes this machine a favorite of growing companies. Used for free flowing liquids with very small to no particulates, it is adept in foam control and often used in fill-to-level glass applications.



 
 

time gravity filling machine

Time Gravity Filling Machine

Used for water thin liquids with no particulates and whose bulk density and flow characteristics do not change with atmospheric or temperature changes. Usually specified in chemical environments where recirculation is not practical. The time gravity filler is an effective low cost technology with limited flexibility.



 
 

>net weigh filling machine

Net Weigh Filling Machine

Scale based filling system used for products sold by weight. Can be used for bulk products sold in totes and pails as well as for precise weights of smaller volume products that have a very high manufactured value. Output is typically lower with a higher capital cost on this type of filler.



 
 

Peristaltic Filling Machine

Peristaltic Filling Machine

Used for small volume, accurate fills of ultra clean or high value liquids such as reagents, essential oils, pharma preparations and other applications where no cross contamination is permitted. Only low viscosity liquids can be used on this machine.The fluid path is disposable making cleanup very fast and efficient.



 
 

Piston Filling Machine

Piston Filling Machine

Used primarily for thick viscous liquids and/or particulated products with limited changeovers. Examples include liquid soaps, cosmetics and heavy food sauces where positive displacement or high pressure filling is required. Also excellent for volumetric filling of expensive products where high accuracy is needed. Higher capital cost but even small machines can produce very high output.



 
 

Servo Pump Filling Machine

Servo Pump Filling Machine

Extremely flexible and versatile filler designed to fill almost any liquid or semi liquid product in almost any volume. Using state of the art digital controls, this filling technology boasts the fastest changeover and cleanup time of any other technology. Capital cost is significantly higher for this type of filling machine than more conventional types.



 
 

Monoblock Fill Plug Cap Machine

Monoblock Fill Plug Cap Machine

Automatic monoblock fill cap plug systems are typically small footprint platforms designed to handle small or inherently unstable containers that cannot be practically filled and closed on intermittent straight line packaging systems. High capital cost machine dedicated to a narrow range of containers and closures.



 
 

Brine Filling Machine

Brine Filling Machine

Used for food products filling brine and vinegar solutions into various sized containers with varying solids contents. Specialty overflow filling machine is constructed with anti corrosion characteristics and specialty nozzles depending on the application. This filler solves some unique problems associated with hand packing of food products in liquids.



 
 

pail filling machine

PAIL FILLING MACHINE

Used for bulk filling of 5 gallon pails by volume only. (See Net Weigh Fillers for filling pails, totes and drums by weight) This is an economical alternative to filling pails with bulk chemical and other typical low cost liquid products.



 
 

Drum Filling Machine

Drum Filling Machine

Used for bulk filling of 55 gallon drum filling, tote filling, and liquid filling of other palletized bulk sizes e.g. 25 gallon barrels, etc. Can be configured to fill either by weight or volumetrically (or a combination of both) Available in chemical duty or food grade construction.
