Various types of tubes and valves are further attached to this feeding tank that support inflow of liquid material out of the feeding tank. The size of the feeding tank varies according to that of the gravity bottle filler size and shape.

    • Pump

    Electric pumps are attached with a gravity bottle filler that is responsible for the efficient flow of liquid within the system. The pump circulates the liquid from huge containers to the feeding tank and then in further processes. The power of these processing pumps is less due to the small and compact size of the fillers.

    • Valves

    Valves are the most important part of gravity bottle fillers that are responsible for the accurate filling of liquid material. These valves are electro-mechanically controlled and perform both tasks. The electrical system generates signals when to close and when to open for filling purpose. Whereas, when the signal is received the valves open and close its gate accordingly. The weight and gravitational pull is also controlled by these valves.

    • Filling Nozzles

    The area from where the liquid gets dispensed out of the system is its filling nozzles. The nozzles are usually made up of stainless steel so that it may be prevented from corrosion and rust.

    • Bottle Platform

    In gravity bottle filler most of the tasks are performed manually. This is why the filler uses bottle platforms instead of conveyor belts. The bottles are place on these platforms and then the filling work is done.

    • Electrical Control Panel

    • Filling Mechanism


    Piston bottle filler has a complete cylinder and piston mechanism incorporated in its construction that is responsible for filling of bottles. The material is supplied from the tank to the filling nozzle through the process pump and from there onwards it is dispensed by the to and fro movement of the piston.

    In contradiction to it, gravity bottle fillers also follow that same procedure till the material reached the filling nozzle. Once the material is to be dispensed there are valves present that release material directly by gravitational pull. No electrical or mechanical supply is required at this step.

    • Product Types

    Piston bottle fillers are best suitable for materials that are viscous and thick in their existing nature.  These can be pastes, creams, sauces and other viscous materials.

    On the other hand, materials like juices, beverages, water, syrups and chemicals that are thin in nature are ideally filled using a gravity bottle filler.

    • Productivity


    As compared to gravity bottle fillers, piston bottle fillers are fast in the filling procedure as they can produce a large number of bottles as filling results. Gravity bottle filler is a bit slow and cannot produce a large number of bottles in a short interval of time.

    • Construction

    Piston bottle fillers are usually compact in size that they can be adjusted on simple tables. Pistons and cylinders are present in it to perform filling tasks.

    Gravity bottle fillers are made up of stainless steel and have no complex structure. Simple tubes, valves, pumps and frames are present in it.
