VPF108SL modified with our FDA approved High Viscosity Valve Assembly designed to handle “sticky” products. It works great with honey and syrup. With the spring check valves needed to manage the sticky products, no bits or pieces larger than 3/8″ can pass through. This setup has 1 inch valves throughout and you’ll be able to fill from 1oz up to 9oz in one pump of medium and high viscosity level products. If your product is thick with a sticky nature, you need this option.
