50–500ml Double-Head Piston Filling Machine with Hopper (Pneumatic)

A pneumatic double-head piston filler designed for medium to high-viscosity pastes and liquids. It uses a rotary valve and piston cylinder mechanism for quantitative filling with adjustable stroke control. ⚙️

Key Features

• Double-head piston system: Extracts and dispenses high-viscosity materials using a rotary valve and cylinder-driven piston.
• Adjustable filling range: 50–500ml per filling, stroke adjusted via magnetic ring switch for repeatable quantities.
• Filling speed control: Adjustable speed ~1–30 bottles/min (depends on viscosity and operator).
• Durable hopper: Large-capacity stainless steel hopper for continuous work.
• Operation modes: Foot pedal or automatic filling (switchable).
• Important: Requires separate air source (air pump not included).

Description

This machine applies a three-way cylinder principle with a rotary valve to handle thicker fluids up to a toothpaste-like viscosity. The piston and rotary valve design reduces dripping and improves quantitative accuracy. A homing knob and speed adjustment make operation straightforward and repeatable.

The unit is intended for use in food, cosmetics, and various industrial filling tasks where controlled, metered dispensing is required. Please verify your material viscosity and prepare a compatible air source before use. 😊

Specifications

Package Included

• Machine
• Hopper
• Sealing ring
• Wrench
• Manual

Usage Tips

• Prepare air supply: This machine requires an external air pump (1000W recommended) — not included. 🔧
• Check viscosity: Suitable for materials up to toothpaste-like viscosity; test feed before production.
• Adjust for speed: Filling speed depends on viscosity, stroke setting, fill volume and operator skill.
• Switch modes: Use foot pedal for manual control or automatic mode for continuous filling.

Care & Maintenance

• Clean parts according to the manual and avoid knocking the rotary valve.
• The rotary valve is made from wear-resistant, acid-resistant, and high-temperature resistant tetrafluoroethylene—handle carefully during cleaning to avoid impact.

Important Notes

• Air source required: Customer must provide compatible air pressure equipment (air pump not included).
• Material limits: Not suitable for liquids with excessive bubbles (e.g., beer).
• Allow 1–3 cm measurement tolerance and slight color differences from photos; please confirm before ordering.

Please read the included manual and labels carefully before first use. If you have specific compatibility or setup questions, check your product specifications and air supply beforehand.
