Intuitive Touchscreen Control
Allows quick adjustment of filling volume, speed, and operating parameters for different lotions, creams, gels, and cosmetic products, helping improve changeover efficiency.

Peristaltic Pump Filling System
Designed for low-viscosity liquids with quick tube replacement, reducing product residue and minimizing cross-contamination during production.

Servo Piston Pump Filling System
Suitable for high-viscosity materials with customizable filling ranges and precise volume adjustment for creams, gels, lotions, and paste products.

Anti-drip Servo Diving Nozzles
Uses a bottom-up diving filling method to reduce foaming, prevent dripping, and improve filling consistency for viscous materials.

90 L Hopper with Optional Mixing & Heating
Large-capacity hopper supports continuous production and can be equipped with optional stirring and heating for thick cosmetic materials.

Material Feeding Piston Pump
Continuously feeds high-viscosity products into the hopper, helping maintain stable material supply and smooth filling performance.

Customizable Chain Conveyor
Conveyor dimensions can be customized to accommodate different bottle sizes, production layouts, and filling requirements.

Stable Electrical Control System
Coordinates filling pumps, nozzles, and conveyor operation to ensure smooth machine performance and stable production.

Why Use a Dual Pump Filling System for Cosmetic Production?

For cosmetic manufacturers handling a wide range of products, one filling pump may not perform equally well across all formulations. The ZS-SVGT4D combines a servo peristaltic pump and servo piston pump so operators can select the filling method according to product characteristics and production requirements.The peristaltic pump is better suited to fluid products such as facial oils, serums and other low-viscosity cosmetics. Because the product mainly contacts the tubing during filling, tube replacement can simplify cleaning and help reduce product residue between batches.For thicker products such as creams, gels and viscous lotions, the servo piston pump provides more stable material handling and volumetric filling. This makes the machine suitable for manufacturers producing multiple cosmetic formulations on the same production line.Pump selection should not be based on viscosity alone. Product flow behavior, filling volume, required output, foaming tendency and changeover frequency should also be considered.

FAQ 

Q1. Can a peristaltic pump fill cosmetic creams?
Peristaltic pumps are generally better suited to fluid cosmetic products such as serums, facial oils and low-viscosity lotions. For thick creams, gels and pastes, a piston pump is usually more suitable because it can handle higher-viscosity materials more consistently. The ZS-SVGT4D combines both systems so different formulations can be filled on the same machine.
Q2. Why combine a peristaltic pump and a piston pump in one filling machine?
Different cosmetic formulations require different filling methods. The peristaltic pump allows quick tube replacement for fluid products and can help simplify product changeovers, while the piston pump is designed for thicker creams, gels and lotions. Combining both systems gives manufacturers more flexibility when producing multiple SKUs.
Q3. Is this filling machine suitable for frequent product changeovers?
Yes. The machine is designed for multi-SKU cosmetic production. For products filled by the peristaltic pump, replacing the product tubing can reduce the amount of filling-system cleaning required between batches. Different operating parameters can also be adjusted through the touchscreen for different products.
Q4. How do I choose between the peristaltic pump and piston pump?
Start with the product's flow characteristics. Fluid products such as oils and serums are normally better suited to the peristaltic pump, while thicker creams, gels and viscous lotions are generally better suited to the piston pump. Filling volume, target speed, product behavior and cleaning requirements should also be considered. Material samples can be tested before confirming the final configuration.
