When we considering to purchase a filling machine, we may be troubled by the measuring methods of the filling machine. There are many different type filling machines on the market, such as weighing, gravity, piston pump, rotary lobe pump, and flow meter. The degree of automation can be divided into semi-automatic filling machines and automatic filling machines. These filling machines each have their own advantages and uses.
The demand for piston pump filling machines and rotor pump filling machines is relatively high. Now I will provide a detailed introduction to piston pump and rotor pump types so that those who cannot make a choice can better understand these two types.
Piston pump filling machine
Rotor pump filling machine
Piston pump filling machine
The piston pump filling machine is a highly adaptable high-speed filling machine, It is also a type of filling machine with higher sales in our company. it can be used to fill thin, Semi viscous and high concentration liquids or products with small particles, such as shampoo, cooking oil, lubricants, honey, mayonnaise, chili sauce, and other viscous or non viscous materials.
According to the customer’s speed requirements, it can be 2 heads, 4 heads, 6 heads, 8 heads, 10 heads, etc. It can be filled with 100-1000ml and 500-5000ml.
Working principle
There is a hopper at the top of it. When the main engine is working, the liquid in the tank is sucked into the piston cylinder, and then the cylinder drives the piston and rotary valve to push the material through the pipeline to the filling nozzle, the magnetic spring switch controls the stroke of the air cylinder to adjust the filling volume. It uses a special filling valve to fill materials through the reciprocating motion of the cylinder.
Main Features
1.The filling volume and filling speed can be adjusted freely on the touch screen.
2.The filling head can choose drip-proof, wire drawing-proof, and suck back for the last dropper.
3.Using a servo drive system, the filling process is stable and the filling accuracy is high.
4.Filling can be done from the mouth of the bottle or from the bottom of the bottle. Filling from the bottle mouth for non foaming products during the filling process. Filling from the bottom of the bottle which is three-step filling, it can be started slowly from bottle bottom, then accelerated to a faster speed, and finally slowed down again to the end. This prevents the foam liquid from foaming and overflowing.
5.It is suitable for various bottle types, and can be adjusted directly according to the bottle type when changing.
6.Highly adaptable, suitable for food, medicine, daily chemical, pesticide, and other industries.
Rotor pump filling machine
The rotor pump filling machine uses a rotor pump for quantitative filling and accurate filling and is mainly applicable to the filling of viscous materials, such as chili paste, bean paste, mayonnaise, honey, face cream, facial milk, etc. with particles or without particles.According to the customer’s speed requirements, it can be 1 head, 2 heads, 3 heads, 4 heads, 5 heads, etc. It can be filled with 100-1000ml and 500-5000ml.
Working principle
It has a separate servo motor to drive the rotor pump to supply production materials to each individual filling head, thereby achieving precise filling.
The so-called rotor pump is a common centrifugal pump that consists of a rotor, stator, and pump casing. Its working principle is that the motor drives the rotor to rotate, and the central axis of the rotor is at a certain angle to the pump axis. At the same time as the rotor rotates, centrifugal force sucks the fluid into the pump from the inlet, and as the rotor rotates, the liquid is pushed towards the outlet to complete the transportation process)
Main Features
- Wide application range,It can be used for bottles of different sizes and shapes.Easy and fast adjustment.
- Fast filling speed,the speed oftwonozzles can reach 30-40 bottles per minute.
- It can quickly switch various bottles and products without adjusting the position of the traditional cylinder, bottle clamping device, and filling nozzle, saving a lot of time for bottle replacement.
- Simple operation and easy cleaning. Automatic cleaning function: without manual disassembly, it can be set once on the touch screen to automatically clean and drain the sewage.*
- Design different positioning devices according to the actual situation of the bottle.
- Compared to other filling machines, it has a smaller footprint.
- CIP cleaning is optional.It can be connected to the CIP system.
- It can be made into a tracking type, and the speed can be faster.
The above is my brief introduction to piston filling machines and rotor pump filling machines, hoping to be helpful to those who are preparing to purchase the machines. Overall, if your material is thin or semi viscous, or if you want a more versatile machine, you can choose a piston filling machine.
If your product is viscous or contains certain particles, and you care about cleaning, then the rotor pump filling machine is your best choice.
There are many types of filling machines on the market. and it is crucial not to blindly purchase them without understanding them. Choosing the right one based on your needs is crucial. Factors such as product type, viscosity, acidity and alkalinity, and bottle size need to be considered. If you have any concerns or questions, please feel free to contact us at any time. We can help you develop the best solution that suits your needs.
