ABSTRACT:
A system for the prevention of jamming of pumps used with containers having a liner therein. The system includes a container having a disposable liner contained therein, a pump and a housing attached to the lower end of the pump. The housing has at least one downwardly extending leg which serves to hold down the disposable liner thereby preventing the pump from being clogged or damaged by pieces of the flexible liner. The housing also has at least one passage therethrough to allow the flow of the medium being pumped upwardly through the housing central cavity. The invention is particularly adapted to the pumping of grease.
