VEVOR SY-580-V2 Liquid Filling Machine: how it works and what it handles

The VEVOR SY-580-V2 is a small automatic liquid filling machine. You set the amount you want, place a bottle under the nozzle and the pump fills it to that quantity. It is aimed at small-batch work, such as bottling milk, vinegar, soy sauce or other thin liquids, where filling by hand is slow and uneven.

How the diaphragm pump works

A diaphragm pump moves liquid by flexing a membrane back and forth, which pushes fluid through the outlet. It is common in small dosing equipment because it can run without a complicated seal. VEVOR says this machine reaches a maximum flow of about 135 fl oz per minute (4 L/min) for low-viscosity liquids over a range of about 78.7 in (2 m). The brand notes that thicker liquids flow somewhat slower, so the rate depends on what you pour.

Digital quantity control

Instead of working through menus, you enter the quantity you want, from 10 to 4,000 ml according to the model name, and the machine does the rest. Setting a volume rather than a time can make repeat fills more consistent. In practice, accuracy on any pump-based filler depends on liquid thickness, tubing length and how it is set up, so it is worth running a test fill and weighing or measuring the result.

Conveyor sensor interface

The listing mentions a conveyor belt sensor interface. This lets the machine work alongside a conveyor, so containers can be moved into position automatically rather than placed by hand. If you only fill a few bottles at a time, you can ignore it and place containers manually.

Materials and cleaning

VEVOR states that the parts the liquid touches are food-grade, that the casing is stainless steel, and that the inlet hose has a mesh filter to screen out foreign particles. The inlet and outlet hoses are described as easy to reach, which helps with taking the machine apart for cleaning. Rinse thoroughly between different liquids, and read the manual about which cleaning agents are suitable.

Size and weight

It measures 7.1 x 5.0 x 3.8 inches (about 18 x 12.8 x 9.7 cm) and weighs about 5 lb (2.5 kg), so it can be carried in one hand and stored on a shelf.

Which liquids it suits

VEVOR lists milk, water, wine, beverages, soy sauce, vinegar and alcohol. These are generally thin or medium-viscosity liquids. Very thick products such as syrups, creams or pastes would flow slowly or may be outside what a diaphragm pump handles well, so check the manual's limits.

Who it suits

It suits small food producers, home bottlers, market sellers and workshops that fill the same container sizes repeatedly and want a tidy, repeatable process without an industrial line.

What to check before you buy

• Your liquid: confirm its thickness and whether it is compatible with the pump and hose materials.
• Container size: check the nozzle height and the gap beneath it for your bottles.
• Power supply: confirm voltage and plug type in the manual.
• Volume range: make sure your target fill sits within 10-4,000 ml.
• Regulations: if you sell what you fill, check local rules for food or drink production.
• Spare parts: find out how to get replacement hoses and filters.
