5 Important Things to Know about Liquid Filling Machines

There are multiple types of liquid filling equipment. Some of these machines are manually operated, while others are fully automatic. Some feature one single head while others have a multi-head configuration that makes them extremely efficient.

If you’re seeking to buy automatic liquid filling machines, you may find this article useful. Even though you’ll have to do more research to make your final decision, here are the 5 most important things to consider right off the bat:  liquid viscosity, container types, fill rates, specific fill volumes, and the specific type of metering and filling system that suits your needs. Please find out more details about each of these factors below.

Liquid Viscosity

The better you understand the basic features of your product, the easier it will be for you to identify the ideal liquid filling equipment. Is your product a water-like fluid, a semi-viscous, or a thick one? The viscosity of the fluid will determine the ideal choice of equipment. Product viscosity can impact your decisions in regard to the metering system, fill rate, and several other variables of the production process. The first step in finding the right machine is the accurate identification of the product viscosity.

Container Type

The type of container you want to fill can also make a huge difference. It matters whether you want to fill plastic or glass, square or round, stable or unstable, short or tall, small or large containers. The main point is that the type of container can influence the design of your liquid filling systems.

Fill Rate

Most production business owners are interested to know how many containers they can fill per day, production, shift, hour, or minute. They are right to ask such questions. An automatic machine with multiple heads will surely fill more containers than a single-head manual one. You can start from your desired rate and work your way up to the type of equipment that would best suit your needs and your specific type of liquid product.

Fill Volume

Even though knowing the specific filling volume sounds fairly easy, you can only calculate it in conjunction with other factors such as product viscosity, metering systems, and fill rates. Also, different industries have different filling accuracy requirements. It’s always a good idea to to keep compliant with your industry standards. This is why you have to know them and to take them into account when shopping around for a liquid filling equipment for your business or production facility.

System Types

Metering and liquid filling systems come in a wide array of types. Metering systems, for instance, can be peristaltic, flow, or piston powered. The fill volumes and the product viscosity will influence your choice of metering system. Also, the changeover times between recipes may influence your pump choice. Before being able to choose the right system, you have to know very well both the characteristics of your liquid and the details of your production process. Even a small detail may lead to selecting a different type of pump or metering system.

Here are the main types of liquid filling equipment:

  • Semi-automatic, single head, handheld benchtop machines
  • Intermediate full line automatic machines
  • Fully automatic, integrated monobloc equipment


In conclusion, liquid filling systems can be used for a side range of products, not necessarily produce. A few examples can be tomato paste, medicines, and petrol. The best liquid filling system is the one that has been designed to work with your specific kind of product. Also, the characteristics of the machine will influence its price. Manual liquid filling systems can range between £400 and £1000. On the contrary, more complex, semi-automatic or automatic systems can cost anywhere around £10,000.
