SHURFLOW OVERVIEW
SHURflo’s Beverage Gas Pump supplies syrup under pressure to a post-mix dispenser, which mixes the
syrup with water to an exact ratio (brix). The pump is used in conjunction with non-pressurized Bag-In-
Box (B-I-B) containers and a bag connector (Q.D.) fitting.
The pump can be operated on regulated C
O2, nitrogen or compressed filtered air. The compressed gas
drives the pump and is not in contact with the syrup. Separate syrup and gas chambers prevent
contamination, foaming, and purging of the tubing when the B-I-B has emptied.
The pump retains pressure in the outlet line, operating only when syrup is needed. When the dispenser
valve is opened, the pump reacts to the pressure drop by operating to maintain pressure in the line.
When the dispenser is closed, the incoming gas and output syrup pressures equalize and the pump
stops. Actual dynamic line pressure is dependant upon system losses as outlined in the section
"Pumping Capability".
The automatic "sold-out" feature within the pump ensures consistent syrup delivery right up to the
moment the B-I-B is empty. Vacuum produced by the pump evacuates the syrup within the bag. Once the
preset vacuum point is achieved and held, incoming gas pressure to the pump is shutoff causing the
outlet syrup pressure to drop to zero. When a new B-I-B is installed, the vacuum drops, the pump
automatically restarts and pressurizes the system. The SHURflo Beverage Gas Pump ensures quality
from the first drink to the last.
Beverage Gas Pumps are intended for soda syrups and low viscosity concentrates that do not contain
solids.
The use of a SHURflo Juice Pump (-09) is recommended for concentrates containing soft solids, classed
as round, up to 0.025 in. [0.6 mm] or that are of higher viscosity than soda syrups.
When concentrates contain pulp classed as long/stringy, seed particles or are exceptionally viscous, the
Particulate Juice Pump (-10) should be used as it can handle soft solids up to
1 /4" [6 mm] cubed.
Standard gas pump models are for installations where geographic elevation is less than 5000 ft.[1523M].
For elevations above 5000 ft. specific high altitude models with a reduced sold-out spring rate must be
used to compensate for the loss in atmosheric pressure.
For further application and model information please contact SHURflo.
