Semi Automatic Check Valve Piston Filling Machine for Thin Liquids en Wenzhou, Zhejiang, China

Semi automatic table top volumetric piston bottle liquid filling machine for free flowing liquids is highly accurate, dependable and accurate piston bottle filler mainly for low viscous liquids. This liquid filling equipment works on a check valve principle. On the intake stroke, the piston draws the liquid directly from the supply tank or or drum, eliminating the need for a hopper, through the upper check-valve and into the cylinder of the piston chamber or liquid cylinder. On the down stroke, the liquid flows through the lower check valve and the liquid is forced from the chamber through the valve and into the container.The big advantage of a check valve filling system is that it can self prime and draw product directly from a drum or other container without need for pumping or otherwise transferring product to another vessel. Simply drop the hose into the drum, adjust the fill volume and start filling products with excellent accuracy of +/- one percent.
