25 caliber servo rotor pump filling machine is a piece of equipment commonly used for liquid filling

Working Principle

• Working Principle of the Rotor Pump: It mainly consists of a pair of synchronously rotating rotors (such as gear rotors, cam rotors, etc.). These rotors rotate within the pump body and convey liquid by periodically changing the volume of the pump chamber. When the rotors turn, the liquid is sucked into the pump chamber. As the rotors continue to rotate, the liquid is carried to the outlet and then extruded under pressure, thus achieving the conveyance of the liquid.

• Filling Process: Under the action of the rotor pump, the liquid is transported from the liquid storage tank to the filling head. The filling head is usually equipped with high - precision valves and flow control devices. When the container reaches the filling position, the valve of the filling head opens, and the liquid flows into the container under the pressure of the pump. By controlling the opening time of the valve or the rotational speed of the pump, the filling volume can be accurately controlled.

Features

• High - precision Filling: Equipped with a servo system, the flow rate of the rotor pump can be accurately controlled, enabling high - precision filling. The filling error can be controlled within a small range. For example, for the ZB - 25 model, the positive and negative error is ≤ 4 grams.

• Wide Application Range: It can handle various liquids with different viscosities. For low - viscosity liquids such as beverages, it can perform filling at an appropriate and stable speed. For high - viscosity liquids such as honey and ketchup, it can also carry out filling with excellent results.

• Good Hygiene Performance: Many components of the rotor pump filling machine are made of food - grade or pharmaceutical - grade materials, such as stainless steel 304 or 316L. Moreover, its structural design is convenient for cleaning. For example, the pump body and pipes can be disassembled for cleaning, and the filling head is also easy to clean, meeting the hygiene requirements of food and pharmaceutical production.

• High Stability: Due to the relatively stable working process of the rotor pump, it can maintain a stable flow rate and pressure during long - term filling operations. This is very important for large - scale production lines as it can reduce equipment failures and filling quality problems, and improve production efficiency.

• Strong Self - priming Ability: It does not require additional auxiliary equipment and can suck in materials on its own, which is convenient for operation and reduces the complexity and use cost of the equipment.

• Customization Service: The manufacturer supports customization. It can carry out personalized design and adjustment according to the special needs of customers and the production environment, which can better meet the requirements of different production lines and match the production processes and techniques of enterprises well.

Application Fields

• Food Industry: It is used to fill various food liquids, such as edible oils, fruit juices, jams, dairy products, etc. It can accurately fill the specified amount of food liquid into bottles and protect the quality of the food from damage.

• Pharmaceutical Industry: It is crucial for filling various pharmaceutical solutions and medicaments. For the filling of drugs such as injections and oral liquids, equipment with high precision and high - hygiene standards is required. The rotor pump filling machine exactly meets these requirements. It can ensure the accurate filling amount of drugs and protect the sterility of the filling process at the same time.

• Daily Chemical Industry: It is used to fill products such as shampoos, shower gels, and lotions. These products have a wide range of viscosities. The rotor pump filling machine can adapt to daily chemical products with different viscosities and can carry out flexible filling according to the different requirements of product packaging.

Selection Considerations

• Filling Capacity: Select a filling machine that can meet the filling capacity range according to actual production needs. For example, if you need to fill small - dose products, such as 5 - 100 - milliliter oral liquids, then choose a 25 - caliber servo rotor pump filling machine suitable for this capacity range.

• Production Speed: Consider the filling speed required on the production line to ensure that the equipment can meet the production efficiency requirements. For large - scale production, a filling machine with a high filling speed needs to be selected to increase production output.

• Material Characteristics: Select a suitable filling machine according to the characteristics of the filling material, such as viscosity, fluidity, and corrosiveness. For high - viscosity materials such as honey and sauces, the 25 - caliber servo rotor pump filling machine can adapt well. However, if the material is corrosive, a filling machine with corrosion - resistant materials needs to be selected.
