PUMP SANITIZING
The SHURflo Juice pump is only one piece of a beverage dispensing system. Therefore, frequent sanitization
of the pump and
ALL
equipment in the system is required.
Sanitization is dependent on the concentrate
type and its' manufacturers requirements.
Factors which also affect the frequency of this procedure are,
temperature, facility conditions, installation, and equipment. Consult other equipment manufacturer's
instructions for their sanitizing requirements. Perform the following procedure to assure compliance with NSF
listed sanitizing requirements for the SHURflo Juice pump
(only)
. Ref.: SHURflo Service Bulletin
#
1025
MATERIALS REQUIRED:
•
Common household bleach (Sodium Hypochlorite; 5.25%) or equivalent.
•
Common household
non-sudsing
liquid detergent, suitable for use in a automatic dish washing machine.
•
An adapter is needed to hold the bag connector on the syrup inlet (suction) line open. A fitting cut
from an empty B-I-B will serve as the adapter.
•
A 6 ft.
[2 M]
length of
1
/
4"
[6 mm]
tubing with a SHURflo output fitting. (To serve as the bypass hose)
•
Two five gallon buckets
[19L]
•
Measuring cup
SANITIZING PROCEDURE
1.
Turn
OFF
CO
2
pressure to the pump. Open the dispenser valve to drop the line (outlet) pressure.
a)
Remove the liquid outlet fitting from the pump. Install the bypass tube fitting in the outlet port of
the pump and screw in place.
b)
Immerse the bag connector and inlet suction tubing in 2 gallons
[7.5L]
of warm water (120-180
°
F
[48-82
°
C]
).
2.
Turn ON CO
2
to the pump (approx. 20 psi.
[1.4 bar]
), and pump the 2 gallons of warm water through
the pump to flush out concentrate residue. Turn OFF CO
2
pressure to the pump.
3.
Prepare 1 gallon
[3.8 L]
of detergent solution in a clean container. Mix at the ratio of 1 oz.
[30 cc]
of
detergent per each gallon of warm water.
a)
Place the bag connector in the detergent solution
b)
Pump approximately
3
/
4
gallon
[2.8 L]
of detergent solution through the pump.
c)
Turn
OFF
CO
2
pressure to the pump. Allow the detergent solution to remain in the pump for a
contact time of two minutes.
d)
Turn the pump upside down and operate the pump until the remaining detergent solution is
pumped out. Turn
OFF
CO
2
pressure.
4.
Repeat steps; 1b) and 2 (i.e.: flush with 2 gallons of warm water.)
5.
Prepare 1 gallon
[3.8 L]
of sanitizing solution (Hypochlorite) in a clean container. Mix at the ratio
1
/
4
oz
[7.5 cc]
of bleach per each gallon of water to obtain a mixture of 100 ppm.
a)
Place the bag connector in sanitizing solution container.
b)
Pump approximately
3
/
4
gallon of sanitizing solution through the pump.
c)
Turn
OFF
CO
2
pressure to the pump. Allow the sanitizing solution to remain in the pump for a
contact time of two minutes.
d)
Turn the pump upside down and operate the pump until the remaining sanitizing solution is
pumped out. Turn
OFF
CO
2
pressure.
6. PRODUCT PURGE:
Connect bag connector to the concentrate B-I-B. Operate the pump until a
steady stream of concentrate flows through the bypass tubing. Pump approximately 10 oz.
[300 cc]
of
concentrate through the pump. Turn
OFF
CO
2
pressure.
7.
Disconnect the bypass tubing and reinstall the concentrate line to the dispenser. Reset pump to the
original CO
2
pressure. Test the dispensing valve for proper operation. Sample the dispensed drink
for proper brix and to assure that there is no off-taste. If an off-taste is detected additional
concentrate purging may be necessary.
