Automatic Inline Gear Pump Filling Machine with Food-grade 304 Stainless Steel and High-precision Frequency Conversion Control for Multi-Stage Filling
The Automatic Inline Gear Pump Filling Machine is engineered for accurate, stable, and efficient filling of liquid and semi-viscous products. Its rotary positive-displacement gear pumps move a controlled quantity of product with every operating cycle, creating a smooth and dependable filling process.
Containers travel through the machine on a linear conveyor and are automatically separated, positioned, filled, and discharged. Each filling head can be independently adjusted, allowing the system to maintain balanced output across multiple nozzles while accommodating different products, filling volumes, and container formats.
The machine is suitable for edible oils, sauces, syrups, detergents, lubricants, cosmetic liquids, gels, light creams, and other homogeneous, flowable products. Its pump-based design provides greater control than gravity filling when the product requires active transfer or when viscosity varies within the intended operating range.
Available with single or multiple filling heads, the system can operate as an independent machine or integrate with bottle feeding, capping, sealing, labeling, coding, inspection, and collection equipment.
The gear pump transfers a controlled quantity of product through each rotation, supporting stable and repeatable dispensing.
Continuous rotary movement creates a steady filling flow with limited pulsation, helping reduce sudden pressure changes and splashing.
Each filling head can be calibrated separately to improve consistency across all nozzles and compensate for minor flow differences.
The required volume can be set by controlling pump speed, operating time, or the programmed number of pump rotations.
The system can handle many free-flowing and semi-viscous products, including oils, sauces, syrups, detergents, gels, and lubricants.
Different filling speeds can be programmed within one cycle to accelerate the main fill and slow the final stage for cleaner, more controlled dispensing.
Anti-Drip Nozzle System
Positive shut-off nozzles and optional pump-reversal functions help minimize dripping, stringing, and product residue.
Adjustable guide rails, bottle sensors, and indexing devices position containers accurately beneath the filling nozzles.
Filling parameters, pump speeds, nozzle positions, and conveyor guides can be adjusted for different products and container sizes.
The machine can synchronize with upstream and downstream equipment to form a coordinated automatic filling and packaging line.
-
What is a gear pump filling machine?
It is a filling system that uses rotary gear pumps to transfer and dispense a controlled quantity of product into bottles or other containers.
-
How does a gear pump filler control the volume?
The filling volume is controlled through pump speed, operating time, or the programmed number of gear-pump rotations.
-
What products can the machine fill?
It can fill edible oils, sauces, syrups, detergents, lubricants, gels, light creams, and other homogeneous liquid or semi-viscous products.
-
Is it suitable for highly viscous products?
Suitability depends on the viscosity, pump size, motor power, piping diameter, temperature, and required filling speed. Product testing is recommended for very thick materials.
-
Can it fill products containing particles?
Standard gear pumps are generally intended for homogeneous products without large or hard particles. Suspended solids may cause blockage, wear, or damage unless the pump is specifically engineered for them.
-
Can each filling head be adjusted independently?
Yes. Individual pump parameters can be calibrated to improve filling consistency across multiple nozzles.
-
How does the machine prevent dripping?
Positive shut-off nozzles, check valves, rapid pump stopping, and optional reverse-suction control help reduce residual product flow.
-
Can it fill foaming liquids?
Yes. Adjustable flow rates, staged filling, and optional bottom-up nozzle movement can help control foam and splashing.
-
Can it handle different bottle sizes?
Yes. The nozzle height, guide rails, bottle sensors, positioning devices, and conveyor settings can be adjusted for different containers.
-
Can the machine be customized?
Yes. The pump capacity, filling range, nozzle quantity, product-contact materials, feeding system, conveyor dimensions, and control functions can be configured around the application.
