AL4-5000 Liquid Filling Machine

core Abstract

The AL4-5000 is a fully automatic four-nozzle piston liquid filling machine from Wenzhou T&D Packaging Machinery Factory, engineered for small-to-medium food & beverage, edible oil, alcohol, daily chemical, and pharmaceutical producers. It fills 5–5000 ml per cycle at 1–100 times per minute with ±1% accuracy, and switches freely between semi-automatic (foot pedal) and fully automatic (timer) operation. Its full pneumatic drive runs without electricity — an intrinsically safe, explosion-proof design ideal for flammable workshops — and every liquid-contact part is food-grade 304 stainless steel (316 optional), with 200°C-rated silicone O-rings and bottom-close anti-drip nozzles (3–12 mm) guaranteeing zero dripping. In stock, shipped by sea, backed by a 1-year warranty.

IV. Sales Recommendations & FAQ

Sales Recommendations

Main Selling Points: No-electricity explosion-proof design + Food-grade stainless steel + Anti-drip nozzle. Ideal for safety production needs in food, chemical, and pharmaceutical industries.
Target Customers: Small to medium-sized food & beverage factories, edible oil/alcohol filling workshops, daily chemical product manufacturers, and pharmaceutical packaging enterprises.
Closing Pitch: Goods in stock + Ocean freight included + 1-year warranty (great for quick conversion).
Upsell / Add-ons: Ask for customer filling volume requirements to recommend models (6 ranges from 5-150 ml to 500-5000 ml); recommend 316 stainless steel + rubber seals for corrosive liquids; recommend 304/316 food-grade configuration for high hygiene standards.

FAQ

Does the machine require electricity?
No. Full pneumatic drive only requires connecting an air compressor to operate safely and explosion-proof.
What liquids can it fill?
Suitable for liquids with good fluidity: water, edible oil, juice, milk, alcohol, liquid medicine, dishwashing liquid, etc.
How is the filling accuracy? Will it drip?
Accuracy is within 1%. The nozzles use a bottom close positive shutoff design to ensure zero dripping.
How to operate it?
It can be operated via foot pedal switch or automatic timer for continuous filling. Easily switch between semi-automatic and automatic modes.
What is the warranty policy?
1-year warranty. Free repair or replacement for damage under normal operation during the warranty period (shipping costs from China to destination borne by customer). On-site engineer travel expenses are borne by the customer. Lifetime maintenance provided after the warranty expires.
Can nozzle sizes or the number of filling heads be customized?
Yes. Nozzle diameter options range from 3–12 mm, and filling heads can be customized to single-head or double-head (default is 4 heads).
What is the delivery lead time?
In stock. Ships immediately after payment (including sea freight).
