Semi-Automatic Pneumatic Piston Sauce & Paste Filling Machine (50-500 mL)

50-500 mL pneumatic piston sauce and paste filler

Volumetric filling for sauces, creams, pastes and suitable liquids

This semi-automatic filling machine measures each dose by piston stroke and uses compressed air as its working power. It is mainly used for sauces and paste materials, while also filling suitable free-flowing liquids. The operator places each container below the nozzle and starts the filling cycle by foot pedal.

Semi-automatic pneumatic piston filling machine for sauce and paste products

Working principle

Piston measurement with compressed-air drive

The piston cylinder draws product from the hopper and dispenses a repeatable volume through the filling nozzle. The fill volume is adjusted by changing the piston stroke.

Piston volumetric dosing

Each cycle measures product by the effective piston-cylinder volume rather than by gravity alone.

Compressed-air power

Pneumatic components drive the filling action. A suitable external air compressor is required.

50-500 mL range

The published adjustable range suits jars, bottles, tubes and other small or medium containers.

Liquid and paste materials

The valve, nozzle and seals are selected according to viscosity, particles, temperature and product chemistry.

Operating sequence

Simple semi-automatic operation for flexible production

The operator controls container placement and starts each cycle, making the machine practical for small batches, frequent product changes and businesses that do not need a full conveyor line.

Typical materials

Designed primarily for sauces and pastes, with broad liquid compatibility

Typical products include water, fruit juice, edible oil, sauce, ketchup, honey, peanut butter, toothpaste, cosmetic cream, hand cream, shampoo, gel and other liquid or paste materials.

  • Food: sauce, chili sauce, ketchup, mustard, honey, syrup, peanut butter, juice and edible oil.
  • Cosmetics: cosmetic cream, hand cream, lotion, shampoo, gel and skin-care paste.
  • Pharmaceutical products: suitable liquid, gel and paste products after contact-material confirmation.
  • Chemical products: detergent, glue, lubricant and other compatible liquid or paste materials.

Sauce and paste filling is the main application

The piston measuring system is especially useful when gravity filling is unsuitable for a thicker product. Products containing particles may require a larger valve and nozzle. Send the material viscosity, particle size and filling temperature so the correct configuration can be selected.

Machine details

Stainless steel product path with adjustable piston stroke

The horizontal layout provides direct access to the hopper, cylinder, adjustment scale, pneumatic components and filling nozzle for operation and cleaning.

Installation and operation

Prepare clean compressed air and enough operator space

  • Use a stable, clean compressed-air supply suitable for the final pneumatic cylinder.
  • Allow space for hopper loading, container positioning, foot-pedal use and filled-container removal.
  • Keep product temperature consistent when filling honey, peanut butter, cream or other viscous materials.
  • Prime the product path and make trial fills before starting each batch.
  • Recheck the filled amount after changing volume, product, temperature or air pressure.

Cleaning and maintenance

Release air pressure before disassembly

  • Disconnect electrical power and release pneumatic pressure before cleaning or service.
  • Clean the hopper, valve, piston cylinder, nozzle and seals with a product-compatible method.
  • Inspect seals, clamps, hoses, fittings, regulator, foot pedal and nozzle regularly.
  • Select food-grade contact parts and cleaning procedures for food or pharmaceutical applications.
  • Keep a replacement seal set matched to the ordered cylinder and valve configuration.

Quotation information

Send product details before selecting the valve and nozzle

  • Product name, ingredients, viscosity and filling temperature
  • Particle size and concentration for sauces containing solids
  • Minimum, normal and maximum filling volumes
  • Container material, opening diameter, height and sample photos
  • Target containers per minute and working hours per day
  • Voltage, frequency, compressed-air conditions and destination country

When an automatic line is more suitable

Choose an automatic conveyor filling line when you need continuous container feeding, coordinated capping and labeling, higher daily output or less dependence on operator rhythm.

Container reference

Confirm the real container and product before production

The machine can be configured for different containers, but the opening diameter, fill height and product behavior must be checked together.
