About Piston Filling Liquid Machine 2 Filling Head Diving Filling

A piston filling liquid machine with 2 filling heads and diving filling functionality is an industrial-grade liquid packaging solution designed for consistent, high-accuracy filling of containers. The system operates on a positive displacement principle: a piston draws a precise volume of liquid from a hopper and dispenses it into bottles or jars via two independent filling nozzles. The "diving" feature refers to nozzles that descend into the container before dispensing begins, reducing turbulence and minimizing foaming—especially beneficial for aerating liquids like shampoos, soaps, or carbonated beverages.

These machines are commonly used in cosmetics, food processing, pharmaceuticals, and chemical manufacturing. They support a wide viscosity range—from thin liquids like alcohol-based sanitizers to thick creams or gels. With two filling heads, they double output compared to single-head units, making them suitable for small production lines aiming for 500–2,000 bottles per hour depending on cycle time and container size.
