Abstract
A dispensing system for dispensing viscous fluids from flexible packages is provided. The flexible package is connected to a pump by way of a conduit. A buffer system may be provided which results in an emptying of the flexible package of fluid first prior to the emptying of the buffer system. A valve may be provided to isolate the flexible package thereby enabling the flexible package to be removed and replaced with a full package while the pump continues to draw fluid out of the buffer system. Accordingly, the flexible package of fluid may be replaced without interruption of the dispenser. A self-cleaning closure for the outlet to the dispenser may be provided to keep the outlet clean.
