time gravity filling machines
The product bulk supply is pumped into a holding tank above a set of pneumatically operated valves. Each valve is independently timed by the filler’s master computer so that precise amounts of liquid will flow by gravity into the container. Gravity fillers built with bottom up fill capability can handle a wide range of flowable liquids including foamy products.
This type of filler is best suited for liquids with very thin viscosities that do not change with ambient temperature or with batch variation. This machine is also suited for applications where recirculation of the liquid in the fluid path is not desirable. Although this type of filler is used predominantly on products that do not foam, foam may be limited and controlled by subsurface/bottom-up-fill capability.
Water, solvents, alcohol, specialty chemicals, paint, inks, corrosive chemicals i.e. acids and bleach.
This is the most economical type of filling machine for a limited range of applications. It is especially well suited for corrosive chemicals.
