Dual-Nozzle Liquid Filling by Weight
The ZONESUN ZS-DP622W is a semi-automatic diaphragm pump liquid filling machine with two filling nozzles and electronic weighing control. Set the target filling weight, position the containers and run the filling cycle. The scales monitor the weight during filling, and filling stops when the preset weight is reached.
Designed for suitable particle-free liquids, this machine is available in 110 V and 220 V versions with two selectable filling ranges. Choose the range in grams or kilograms according to your target fill weight.
Key Features
- Weight-based filling: Electronic scales provide real-time weight feedback during the filling cycle.
- Two filling nozzles: Foot pedals allow separate control of the nozzles. Nozzle height can be adjusted to suit the containers.
- Control panel: Set the filling weight and flow setting and select the operating mode.
- Semi-automatic operation: The operator positions and removes containers. This is not a conveyor-fed automatic bottling line.
Choose Your Filling Range
| Option | Target Filling Weight |
|---|---|
| 150g-9999g | 150 g to 9999 g |
| 150g-20kg | 150 g to 20 kg |
The filling range applies to the selected configuration. The electronic scale's weighing range does not extend the machine's selectable filling range. Weight and volume are different: converting grams to milliliters requires the density of the actual liquid.
Suitable Liquids & Application Checks
Use this model for compatible liquids without particles. Provide your liquid type, viscosity, operating temperature, target filling weight and container dimensions so we can check the application. Thick shampoo, gels, foaming liquids and liquids requiring special material compatibility need confirmation before ordering.
The listed liquid temperature limit is below 55°C. Actual filling speed and accuracy depend on the liquid, target weight, flow setting, hose arrangement and setup. Confirm expected output and filling tolerance for your application.

Before Ordering
- Select the required voltage and filling range.
- Confirm nozzle size and fit with the bottle opening, as well as container height and scale platform suitability.
- Confirm the number of scales, supplied nozzles, foot pedals, hoses and filters in your selected package.
- If you need different target weights on the two heads or a specific automatic start method, confirm the control configuration before ordering.
Contact ZONESUN with your liquid and container details for configuration guidance.
Machine Details & Operation
The control panel allows operators to set the filling weight and flow rate directly and select the required operating mode.
Choose inching mode for machine testing or automatic mode for production. In automatic mode, filling begins when a bottle is detected.
Both anti-drip nozzles support accurate filling and can be controlled separately using the foot pedals. Their height can be adjusted to suit different bottles.
The scales display each bottle’s actual weight on the control panel in real time. Filling stops when the preset weight is reached.
The filters remove impurities from the liquid to help prevent pump blockages and support efficient pump operation.
