ABSTRACT:
A vacuum operated system for transferring fluid from a container to an open or relatively large sump without applying vacuum to the sump. A small, closed, intermediate chamber is interposed in a flow path between the container and the sump. Vacuum from a small vacuum source is applied to the intermediate chamber and draws fluid from the container through a first conduit into the chamber. A peristaltic pump draws fluid from the chamber through a second conduit to the sump while maintaining a vacuum seal for the chamber preventing loss of vacuum through the second conduit.
