Abstract
A dispenser for high density liquids such as barium sulphate comprising a housing with a bowl seated on the housing and containing the liquid. Refrigeration coils in the bowl chill the liquid, and a variable speed paddle type pump also in the bowl mixes and circulates the liquid about the refrigeration coils and maintains the mixture in suspension. A dispensing valve assembly includes a body having a passage which extends axially through it and a vent tube that extends upwardly from the body. The vent tube and body prevent build up of the liquid about the valve which otherwise would dry and cause valve blockage.
