Automatic 100ml-5000ml Piston Pump Chemical Bottle Filling Machine With PLC Control

Automatic Chemical Bottle Filling Machine

The Chemical Bottle Piston Filling Machine is designed for accurate and efficient filling of a wide range of chemical liquids into bottles and containers. It is especially suitable for medium- to high-viscosity products that require stable volumetric dosing, clean filling, and consistent output.

Chemical products can vary significantly in viscosity, flowability, foaming tendency, and corrosiveness. Therefore, choosing the right filling equipment is important for maintaining filling accuracy, reducing product waste, and improving production efficiency.

Our chemical bottle piston filling machine uses a precise piston dosing system combined with servo control technology. It can handle products such as liquid detergents, cleaning agents, lubricants, automotive fluids, liquid fertilizers, chemical additives, adhesives, and other viscous or semi-viscous chemical liquids.

The machine can be used as a standalone filling unit or integrated with capping, labeling, conveying, and packaging equipment to form a complete automatic chemical bottling line.

Features

1.High Filling Accuracy

The machine adopts a volumetric piston filling system to ensure accurate and repeatable filling. Servo motor control allows precise adjustment of piston movement, helping maintain consistent filling volume from bottle to bottle.

2.Suitable for Different Viscosities

The piston filling principle makes the machine suitable for a wide range of chemical products, from free-flowing liquids to thick and viscous formulations.

3.Servo-Controlled Filling 

Filling volume, filling speed, and piston stroke can be adjusted through the PLC and touch-screen control system, making operation simple and flexible.

4.Anti-Drip Filling Nozzles

Specially designed filling nozzles help reduce dripping, stringing, and product contamination around the bottle opening, keeping the filling area clean.

5.Bottom-Up Filling Option

For foaming chemical liquids, the filling nozzles can move from the bottom of the bottle upward during filling, helping reduce foam, splashing, and overflow.

6.Flexible Filling Range

Different piston sizes and filling parameters can be configured according to the required filling volume. The machine can accommodate different bottle capacities and container formats.

7.Multiple Filling Heads

The machine can be equipped with multiple filling heads according to production capacity requirements, helping manufacturers increase output while maintaining filling consistency.

8.Corrosion-Resistant Configuration

For corrosive or aggressive chemical liquids, product-contact components can be customized with suitable corrosion-resistant materials, seals, valves, hoses, and nozzles.

9.Easy Changeover

Filling parameters can be adjusted quickly through the control system, allowing easier switching between different products, filling volumes, and bottle sizes.

10.Easy Integration

The Chemical Bottle Piston Filling Machine can be connected with bottle unscramblers, capping machines, labeling machines, conveyors, coding machines, and packing equipment to build a complete chemical filling and packaging line.

Chemical Bottle Filling Machine Working Principle

The Chemical Bottle Piston Filling Machine works according to the volumetric piston filling principle.

 During the first stage, the piston moves backward and creates suction inside the measuring cylinder. The chemical liquid is drawn from the product tank into the cylinder until the preset filling volume is reached.

During the second stage, the piston moves forward and pushes the measured liquid through the filling valve and filling nozzle into the bottle.

The servo motor precisely controls the piston stroke and movement speed, allowing the machine to maintain accurate and repeatable filling volumes.

For viscous products, the positive displacement action of the piston provides stable product transfer and consistent dosing. For foaming products, the filling nozzles can descend into the bottle and rise gradually as the liquid level increases, helping reduce foam and splashing.

The complete filling process can be automatically controlled through the PLC system, including bottle positioning, filling volume, filling speed, nozzle movement, and production counting.
