Automatic Demand
- The pump operates only when syrup is needed. When the dispenser valve opens,
creating a pressure d rop, the pump operates to maintain syrup line pressure. The pump continues
operating until the valve is closed and the syrup line pressure equals the gas pressure. At
equalization, the pump stops.
Sold Out
- The pump operates only when there is an adequate supply of syrup. Vacuum produced by
the pump evacuates the syrup within the bag. Once the preset vacuum point is achieved and held, the
gas supply to the pump is shut off, causing the pump to stop. When a new BIB is installed, the pump
automatically starts and pressurizes the system. The benefit of the sold-out feature is that the outlet
line to the dispenser always remains full of syrup.
