How To Choose The Right Liquid Filling Machine For Your Production Line

Liquid filling machines can be found in the factories, production lines. For food, drink, cosmetic, medicine, daily chemical production, the right equipment can make a significant difference to daily operations.

But there are so many types of liquid filling machines in the market now. How can manufacturers know which one is suitable for their production line? The answer depends on their production information. Different liquids, filling volumes, and container types need to be produced on different equipment. This is because that different filling machines have different pump systems and applications.

In this article, we will explain the key factors to consider when selecting an industrial liquid filling machine.

1. Understand the Type of Liquids Your Want To Fill

Before comparing machines or requesting quotations, think about your product. Confirm its viscosity, fluidity, chemical properties, and tendency to foam. All these features influence which filling system will work well.

Non Viscous Liquids

Water, juice, liquid alcohol-free beverages, and some cleaning solutions flow easily. Gravity fillers, flow-meter filling systems, and suitable pump fillers are commonly used for these products.

Medium-Viscosity Liquids

When filling medium viscosity liquids, the equipment should apply more control during dispensing. For these products, pump filling machines or flow-meter systems may be suitable.

High-Viscosity Liquids

Highly viscous products need to be filled by the equipment that has the ability of handling slower-flowing products. Piston pump filling machines are often a practical choice because they dispense a controlled volume through a metering cylinder.

2. Compare the Main Types of Liquid Filling Machines

Different filling technologies are designed for different production requirements. Learning about their strengths and limitations will help you make the informed options.

Piston Pump Filling Machines

Piston pump fillers use reciprocating pistons to measure and dispense a predetermined volume of liquid. They can be used for filling creams, sauces, gels, honey and other products with medium to high viscosity.

Advantages:

• Suitable for many thick or viscous products.
• Provides controlled volumetric dispensing.
• Available in semi-automatic and automatic configurations.

One kind of piston pump fillers is the ZS-YT2T-2PXD Automatic 2 Heads Servo Filling Machine. This model uses servo motor to control the running of pump system. It has higher filling accuracy than the normal fillers. The machine is built with feeding pump, to transfer liquids into hopper. This reduces manual material loading. The ZS-YT2T-2PXD model can be used for filling viscous products into different containers.

Overflow Filling Machines

Overflow fillers are commonly used when consistent liquid levels are important, especially when filling transparent bottles. They are suitable for filling alcohols, drinks, waters, bubble liquids.

The key benefit is visual consistency: bottles can appear uniformly filled even when their internal dimensions vary slightly. This is particularly useful for consumer products displayed on retail shelves.

Peristaltic Filling Machines

Peristaltic filler uses an independent tubing to transfer liquids into containers. It is suitable for the products that require non-contamination filling. The peristaltic liquid filling machines can be used for filling eye drops, biochemical solutions, perfumes.

3. Determine Your Target Production Capacity

Production speed is another important factor when choosing a suitable liquid filling machine. A small manufacturer and workshop requires to fill a few hundred bottles per day. And a beverage plant need to run multiple shifts to produce thousands of containers per hour. Therefore, their requirements for filling equipment are different. Before searching for machines, please confirm your actual production target.

Think about the following questions:

• How many bottles or containers do you need to fill per hour?
• How many hours will the machine operate each day?
• How many shifts will your production line run?
• Will you fill one container size or several?

The filling speed displayed on website does not reflect achievable output of your production. Actual operating speed will change according to filling volume, liquid viscosity, the level of operator involvement, changeovers, and the status of downstream equipment.

The ZS-VTGF4 Automatic 4 Tracking Heads Servo Gear Pump Hand Soap Filling Machine from ZONESUN PACKAGING is the one that suits for filling viscous liquids. It uses servo gear pump to accurately control the filling volume. And its main feature is the tracking filling heads. The heads can follow with the bottles on the conveyor, realizing efficient filling work. The ZS-VTGF4 model can be used for filling creams, gels, shampoos, body lotions, liquid soaps.

4. Choose a Reliable Liquid Filling Machine Manufacturer

A suitable liquid filling machine supplier is as important as a liquid filling equipment. It is important to learn about the technical experience, manufacturing capabilities, and after-sales service of the manufacturer.

Here are several questions worth asking:

• Has the manufacturer supplied equipment for similar products and applications?
• Can the machine be tested using your actual liquid and containers?
• What production speed and filling accuracy can be demonstrated?
• Are installation, commissioning, and operator training included?
• How quickly can replacement parts be supplied?
• What warranty and technical support are provided?

Conclusion: Select a Liquid Filling Machine That Fits Your Production Needs

The liquid filling machine you need should match with your production needs. The liquid properties, filling range, container design, and production capacity are all the things you need to confirm. The manufacturers with higher output requirements may benefit from an automatic liquid filling machine that is connected with capping, labeling, and case packing machines.

FAQs

Q1: How To Choose The Right Liquid Filling Machine For My Product?

A1: First, consider the viscosity of products, filling volume, required production speed, and cleaning requirement. They are the factors that influence the type of liquid filling machine. For example, piston filling machines can be used for viscous liquids. And magnetic pump filling machines are suitable for non-viscosity liquids. Before purchasing, test the machine with your product and containers, and check the filling accuracy and performance.

Q2: Can one liquid filling machine be adjusted for different container sizes?

A2: Yes. Semi-automatic and automatic liquid filling machines can be adjusted to suit for multiple products and container sizes. They are usually equipped with adjustable filling heads, product-contact components and programmable controls. This facilitates changeovers. When switching from one product to another, operator needs to clean the material contact parts and reset the settings. Besides, when producing foods, cosmetics, chemicals, manufacturers need to check the cross-contamination risks.

Q3: Can one machine performs filling and capping processes?

A3: Yes. The machine that combines filling and capping functions is called Monoblock Liquid Filling Machine. It is designed for the ones who have limited working space.
