The Application of Longer Product in Liquid Filling Machines

Application Introduction:

The Liquid filling machine is a kind of packaging machine which fills packaging containers with a fixed quantity of liquid. The liquid filling machines can be classified into three types depending on their principle use, these are: vacuum filling machines, pressurized filling machines and filling machines which use atmospheric pressure. And according to the machine structure the liquid filling machines can be classified as either linear or rotary filling machines, they can also be classified as either single head or multi-head filling machines according to the quantity of heads. The liquid filling machines serve a wide range of applications, such as in the food & beverage industry, where packages are filled with milk, juice or water, or in the pharmaceutical industry where sterile medical packages can be filled with vaccines, sterile oral medicines or injections; and in the cosmetic industry, where packages are filled with skin care liquids or detergents.






The Customer Requirement:

Variable filling volume
High filling accuracy
High filling efficiency 
No contamination
Stability and reliability
Suitable for abrasive liquid with particles 
Suitable for corrosive liquid
Suitable for shear-sensitive substances
Good breakoff and no droplet

Easy operation and maintenance 




Longer Pump Solution:

1. Longer Peristaltic Pumps have a wide range of flow rate, which can be easily controlled. Repeatable dispensing accuracy is achieved by precise speed control and calibration. The low shear and gentle pump action ensures that biological substances are not damaged during pumping. When pumping fluids, the fluid only comes into contact with the bore of the tubing, thus eliminating the risk of contamination between the pump and fluids. And the peristaltic pump with the correct tubing, can be used to pump corrosive and/or abrasive fluids. 


2. Longer’s Dispensing &Filling System has high filling accuracy and efficiency. The system can be configured using between 4 to 32 peristaltic pump heads, and a filling volume of 0.2ml/s-48ml/s can be achieved, it has a dispensing accuracy of up to ±0.5%. The back suction function reduces the droplet during the filling process.




Customer Value:

1.High precision filling and repeatability help maximize productivity and profitability
Dispensing precision of Longer peristaltic pump <2% 

Dispensing accuracy of Longer dispensing & filling system can be achieved up to ±0.5%


2.Eliminate the contamination risk during the filling process
Using Longer peristaltic pump, the product only contacts the bore of the tubing during the filling process to eliminate the risk of the pump contaminating the product, or the product contaminating the pump.

The tubing of peristaltic pump can be changed simply, providing easy and fast product change with no cross-contamination. 


3.High filling efficiency helps with high productivity

Longer peristaltic dispensing and filling system could work with many different pump head and tubing to provide a wide range of filling volume, 0.2ml/s-48ml/s. The high filling efficiency improves the filling productivity.


4.Reduce the product damaging and protect the product integrity

The low shear, gentle pumping action of peristaltic pump ensures the product will not be damaged.


5.Suitable for abrasive liquid product with particles or corrosive liquid product
Gentle pumping action of peristaltic pump is ideal for the semisolids, heterogeneous mixtures and liquid with particles. When filling the product, the product only contacts the bore of the tubing. By using the tubing with good abrasive resistance, the pump can be used to fill abrasive product. By using the tubing with good chemical resistance, the pump can be used to fill corrosive product.
Soft particle size<25%*ID (tubing inside diameter)

Hard particle size<5%*ID (tubing inside diameter)


6.The customized solution by Longer OEM design optimizes the pump performance

For the special product, special filling volume and special operation requirement, Longer peristaltic pump and peristaltic dispensing &filling system can be customized to meet each customer’s needs. Longer engineers and technical specialist work closely with you to understand your specifications to optimize the performance of your customized equipment.


7.Easy operation and maintenance helps with high productivity and low maintenance cost
Easy pump operation and tubing change of peristaltic pump minimize the downtime and maintenance cost.
