SHURflo HeavyDuty Advantage BIB 94-360-05 Manual page 5

The Post Mix BIB Dispensing system consists of the BIB package and the SHURflo BIB Gas pump. The
BIB package works in conjunction with the Shurflo gas pump to supply syrup to the dispenser.
The BIB package, consists of a non pressurized 5 gallon (20 liter) flexible bag (other sizes are
available), composed of polyethylene and metallized polyester, held inside and supported by a carton
box. The polyethylene film, approved by the FDA, is in contact with the syrup in addition to providing
the bag strength. The metallized polyester film provides an oxygen barrier to the bag for extended
shelf life of product.
The SHURflo pump is driven by CO
supply the system between 20 and 85 psi (1.5 - 5.9 bar). The compressed gas only runs the pump
and never comes in contact with the product. The pressurized line from the pump propels the liquid or
syrup to the dispensing unit. The pump eliminates the need for check valves and manifolds used in
transfer tank systems. The separation of the gas and liquid avoids contamination, foaming and
purging of the liquid outlet lines when the BIB is empty. The Shurflo BIB pump ensures drink quality
from the first drink to the last.
The SHURflo pump is compatible with all types of dispensing equipment.
When designing a Post Mix BIB Dispensing System there are certain points to be taken into
consideration to ensure long-term operation of the p ump and maximizing space efficiency.
BIB Gas Pump Pumping Capability
Beverage dispensing systems have inherent factors that determine the distance syrup can be
delivered. Restrictions within the BIB system's fluid path will affect pumping capability. Before
deciding on a system tubing size, SHURflo recommends estimating system losses by considering the
following:
1. Syrup viscosity and temperature (cold plate, re-circ., etc.).
2. Total syrup flow rate of dispensing valve(s) connected to a pump: add flow rate of valve(s)
connected to a single pump.
Note: the number of pumps is at least one pump per flavor. If there are five flavors in the
dispensing unit, you will need five pumps.
3. Inside diameter of the outlet/inlet tubing, fittings, etc.
4. Vertical and horizontal distance of the outlet tubing.
Vertical tubing runs will reduce total tubing run length. To estimate the losses within the vertical
distance, use the Maximum Horizontal Tubing Length by Viscosity Tables to
Pumping Distance.
