A rotary lobe pump filling machine is a quantitative filling device powered by a high-precision rotary lobe pump. It is specifically designed for the precise filling of high-viscosity, particulate, foaming, and shear-sensitive materials.
This equipment is widely used in the food, daily chemical, pharmaceutical, chemical, and coating industries, enabling stable, efficient, and low-loss automatic or semi-automatic filling operations.

Rotary Pump For Filling Machine | High Accuracy Filling for Viscous Liquids
✅Key Advantages
1️⃣High-Precision Quantitative Filling
Utilizing the principle of a positive displacement rotor pump
Filling accuracy can reach ±0.3% – ±0.5%
Unaffected by changes in material viscosity and temperature
2️⃣Adaptable to a variety of complex materials
Low-shear conveying, does not damage material structure
Can convey high-viscosity, paste, greasy, and soft particle-containing materials
Suitable for media that are prone to foaming, crystallization, and sedimentation
3️⃣Stable filling, no dripping
Fast start/stop response, precise flow control;
Optional anti-stringing and anti-drip structures for the filling nozzle;
Clean and tidy filling process, reducing material waste;
4️⃣Compact structure and easy maintenance
Modular design for easy assembly and disassembly;
No metal-to-metal contact between the rotor and pump chamber, resulting in a long service life;
Low cleaning and maintenance costs, suitable for frequent material change operations;
✅Working Principle
The rotary pump filling machine uses a pair of synchronously rotating rotors to form a sealed conveying chamber within the pump cavity, continuously and evenly pushing the material to the filling port.
The volume or weight of each filling can be precisely controlled by adjusting the motor speed or filling time.
✔ Filling volume = Rotor volume * Speed * Time
✔ Smooth filling process with minimal pulsation and high repeatability
✅Applicable Materials
Food Industry
Honey, chocolate sauce, peanut butter
Jam, tomato sauce, salad dressing
Yogurt, cream, concentrated dairy products

How to Choose a Rotary Pump Filling Machine
When choosing a rotary pump filling machine, a comprehensive evaluation should be conducted based on material characteristics, filling requirements, and production conditions. The following key factors are particularly important:
✔. Material Characteristics
Firstly, clarify the viscosity, flowability, and particle content of the filled material.
For materials with high viscosity, paste, paste, or soft particles, it is recommended to use a large chamber, low-speed rotary pump
For materials that are sensitive to shear or prone to foaming, low shear and smooth conveying structures should be preferred to avoid damaging the medium structure
✔. Filling Volume&Accuracy Requirements
Select the appropriate pump type and control method based on the single filling volume and accuracy requirements:
It is recommended to use a servo driven rotor pump filling system for small dose and high-precision applications
High displacement rotary pumps can be used for high-dose or barrel applications to improve efficiency
✔. Production Efficiency and Automation Level (Production Capacity)
Low to medium production capacity: Single head or double head semi-automatic rotary pump filling machine
Medium to high production capacity production line: multi head rotor pump filling machine, compatible with automatic conveyor lines
Choosing the appropriate number of filling heads can effectively balance efficiency and cost
✔. Material&Compliance
Food and pharmaceutical industries: SUS316L stainless steel is recommended, which meets food grade or GMP requirements
Chemical and corrosive media: optional anti-corrosion materials or special sealing structures
Reasonable material selection can significantly extend the service life of equipment
✔. Cleaning&Maintenance Requirements
If frequent material replacement is required during the production process, it is recommended to choose:
Quick detachable rotor pump structure
Filling machine configuration supporting CIP online cleaning
To reduce downtime and improve overall production efficiency
✔ Professional advice: Before selecting, it is recommended to provide the material name, viscosity range, filling volume, bottle type, and target production capacity. The manufacturer can recommend a more suitable rotor pump filling solution based on this.
