Finding a 4-head automatic liquid filling machine for 10-500 ml bottles, you may have come across multiple listings with the exact same product title and a price gap of roughly $250. When the names match but the prices don't, the deciding factors are the specifics each listing describes and which extras matter to you.
Quick Take
- The lowest listed price comes with a detailed spec table for thin liquids.
- The lower-priced listing that mentions a conveyor belt pairs that package with construction details.
- A high-priced listing gives you the detailed spec table plus a liquid paste filling reference.
- The top-priced listing spells out the full package: conveyor belt, sensors, and stainless steel mainframe.

Product Notes
4-Head Automatic Liquid Filling Machine (USD 280.98)

This is the listing to start with if price is the main gate. The title covers the 10-500 ml filling range, and the description provides a full spec table: 150 W power, diaphragm pump, flow of 4 × 3.2 L/min, 1-4 adjustable nozzles, bottle diameter 20-90 mm, and bottle height 40-250 mm. It also calls out white wine and beverages as the intended applications, which helps if you are bottling thin liquids. The trade-off is that the listing description does not mention a conveyor belt, so this option is best when you already have a conveying plan or want to keep the initial cost as low as possible.
4-Head Automatic Liquid Filling Machine (USD 530.68)

At the higher end, this listing is the lower-priced one that explicitly describes a package with a filling machine host, conveyor belt, and assembly accessories. The description highlights a stainless steel mainframe and aluminum spacer for durability, plus sensors that test the front and back of bottles to avoid chaotic filling. If you want a ready-to-assemble line with a belt, this is the low-priced option among those that mention that package. The limitation is that the description focuses on construction rather than numeric specs, so the flow rate and nozzle count are not spelled out here.
4-Head Automatic Liquid Filling Machine (USD 530.73)

This listing combines a high-end price with a detailed spec sheet. The description includes the same materials list (PVC, stainless steel, aluminum, silicone), 150 W power, 10-500 ml filling range, 1-4 adjustable nozzles, and bottle dimension limits that the USD 280.98 listing has, and it adds a reference to liquid paste filling machine pneumatic bottle filling. At USD 530.73, it's within a few cents of the other high-priced listings, so you are not paying a meaningful premium for that spec detail. The package contents are not described, so this one is best if your priority is having the full technical picture in the description rather than a conveyor belt callout.
4-Head Automatic Liquid Filling Machine (USD 530.91)

This is the highest listed price in the group, but the description gives you the most complete package picture: stainless steel mainframe, aluminum spacer, front/back sensors, and a package that includes the filling machine host, conveyor belt, and assembly accessories. If you want a single listing that spells out the durable build and what's in the box, this is it. The limitation is simply that it's at the top of the price range, and the difference between it and the USD 530.68 listing is only USD 0.23, so you may prefer to choose the slightly lower price among the two that mention the conveyor belt if the descriptions match your needs.
Final Recommendation by Use Case
- Looking for the lowest listed price with detailed specs: Choose the USD 280.98 option. It gives you the full spec table and the lowest price of the four.
- Looking for a conveyor belt in the package and a durable build: Choose the USD 530.68 listing. It is the lower-priced of the two that mention the belt, and it highlights stainless steel construction and sensors.
- Looking for detailed specifications near the high end: Choose the USD 530.73 listing. It offers the spec table plus an extra liquid paste filling reference, without a meaningful price gap.
- Looking for the most complete package description: Choose the USD 530.91 listing. It spells out the conveyor belt, sensors, and durable mainframe, but it carries the highest listed price.
All four share the same product title, so base your final choice on the listed price, the description's emphasis, and whether the conveyor belt is part of the package you want.
