BEVERAGE GAS PUMP 166-296-XX
Installation and Operation Manual
SHURflo's Beverage Gas Pump supplies syrup under pressure to a post-mix
dispenser, which mixes the syrup with water to an exact ratio . The pump is
(brix)
used in conjunction with non-pressurized Bag-In-Box containers and
(B-I-B)
a bag connector fitting. The pump can be operated on regulated
(Q.D.)
CO , nitrogen or compressed filtered air. The compressed gas drives
2
the pump and is not in contact with the syrup. Separate syrup and gas
chambers prevent contamination, foaming and purging of the outlet
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 dependent 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.

APPLICATION INFORMATION

Beverage Gas Pumps are intended for soda syrups and low viscosity concentrates that do not
contain solids.
The use of a SHURflo Juice Pump is recommended for concentrates containing soft solids, classed as round, up to
(-09)
0.025 in. or that are of higher viscosity than soda syrups.
[0.6 mm]
When concentrates contain pulp classed as long/stringy, seed particles or are exceptionally viscous the
1
Particulate Juice Pump (-10) should be used as it can handle soft solids up to / " cube.
[6 mm]

PUMPING CAPABILITY
Beverage dispensing systems have inherent factors that affect the distance syrup can be delivered.
Restrictions within the B-I-B system's inlet/outlet will limit pumping capability. Due to variances in system
configuration and equipment, an accurate determination of pressure drop is difficult. Before deciding on
a system's tubing size, SHURflo recommends estimating system losses by considering the following:
• Syrup viscosity and temperature .
(coldplate, re-circ., etc.)
• Total syrup flow rate of valve connected to a pump.
(s)
• Inside diameter of the inlet/outlet tubing, fittings, etc.
• Horizontal & vertical distance of the outlet tubing.
Vertical tubing runs will reduce total tubing run length. To estimate the losses within the vertical
distance, use the chart to the right. Take 1% of the distance in feet . The resulting number
[3% if meters]
is multiplied by the vertical distance. This product is then subtracted from the maximum horizontal
distance. The resulting length is the total horizontal/vertical tubing run that is obtainable for
(horz./vert.)
that flow rate, tubing I.D. and viscosity.
