JUICE GAS PUMP 166-200-XX
(GREEN LABEL)
Installation and Operation Manual
The SHURflo model
#
166-200
-09
(Standard Juice pump) is for concentrates that contain soft solids classed
as "round" (up to .025 in. dia.
[.6mm]
) or for concentrates that are of higher viscosity than soda syrups.
Model
#

-10
(Particulate Juice pump) is designed to transfer concentrates that contain, pulp
classed as long/string, seed particles, or soft solids up to ¼"
[6mm]
cube. It is also recommend for
concentrates that are extremely viscous. The pumps valve cartridges minimize the collection of
particulates and promotes thorough flushing during sanitization.
Both models of the Juice pump are compatible with concentrates that are highly acidic (low pH value),
and are identified by black inlet and outlet fittings.
Juice concentrates are generally supplied in flexible plastic bags, packaged inside cardboard boxes
(Bag-In-Box). Juice concentrates generally require more frequent sanitization. The manufacturer of the
concentrate should specify the interval for sanitizing; however, other factors such as system
configuration, and/or temperature may affect concentrate life.
(see page: 4)
The Juice pump pressurizes the concentrate to match the pressure of the gas supply. The pump can be
operated on regulated CO
2
, nitrogen, or clean compressed air. The compressed gas is used to operate
the pump and does not come in contact with the concentrate. The pump operates when concentrate is
needed, which is termed as its "automatic demand" feature. When the post-mix dispenser valve is
opened, the pump reacts to the drop in pressure by operating to maintain pressure in the line. When the
dispensing valve is closed, the input gas and output concentrate pressures equalize and the pump
stops. As the B-I-B empties, the pump draws a vacuum collapsing the bag evacuating it of concentrate.
The pump automatically shuts off once vacuum above 20 in/Hg.
[508 mm/Hg.]
is obtained. When a new
B-I-B is connected the vacuum drops, the pump automatically resumes pumping.
PUMPING CAPABILITY
Due to diversity of both the installations and equipment used within beverage systems, it is difficult to
calculate/predict total pumping distance. The ability to deliver fluid is limited by the dynamics of the fluid (flow)
and pump displacement at pressure. Consider all the following factors when estimating pressure drop within
a beverage system.
•
Fluid viscosity (Centipose/cP.) @ temperature.
•
Inside diameter of the inlet/outlet tubing, fittings, etc.
•
Horizontal distance of the outlet tubing.
•
Total syrup flow rate of valve(s) supplied by a given pump.
•
The pressure drop per foot within vertical tubing runs is significant. To estimate the losses use the
appropriate distance given by Max. Horz. Dist. Chart
(page: 2)
. Take 1% of that distance [3% if meters].
Multiply the vertical distance by that number. Subtract the product from the original Max. Horz. distance.
The result is the total tubing run (includes vertical) that should be attempted for that flow rate, tubing I.D.,
and viscosity.
Example:
The facility requires a total tubing run of 196 ft.
[60

; included that run is a 14 ft.

The product is 100% Grape juice dispensed by one fast flow valve (.5 oz/sec

tubing.
1% of 248 is 2.48, which is then multiplied by 14 ft, equaling approximately 35 ft. Subtracted that product
from the 248 ft. (248–35 = 213). 213 ft. is the total tubing run that can be achieved including the 14 ft. vertical.
To calculate the vertical losses for distances measured in meters, take 3% of the distance given [76
M
] =
2.28. Multiply by the vertical meters (2.28 x 4.26 = 9.7). Subtract that product (76–9.7 = 66.3). 66.3
meters is the total tubing run that can be achieved including the 4.26
M
vertical.
NOTE:
Had the example above resulted in a value that was equal to, or less than the necessary total tubing
run, consider a larger I.D. tubing or installation of a pump(s) in series using a vacuum regulator.
