Gas Pump Installation
Considerations
When designing a BIB system, take the following points in consideration to ensure long-term
operation of the pump and maximizing space efficiency.
1. How many pumps?
There should be one pump per flavor. More pumps may be needed based on the total flow
requirements for each flavor.
2. Where to mount?
Each pump is equipped with a mounting bracket and can be mounted in the following ways:
- Wall mount - Space efficient; maximizes vertical space.
- Top mounting bar - Space e fficient; easy to relocate and can be pre -assembled.
- Side of rack - Uses more horizontal space; may shorten distance from BIB to pump.
3.
Location of pump/BIBs
- Low traffic areas - A key benefit of SHURflo BIB pumps is distance pumping capability. This allows
the BIB system to be located out of the employee high traffic areas and in a more strategic
location.
- Away from high heat - heat can distort the plastic parts of the pump and shorten the shelf life of
the syrup. If high heat is a factor in where the pumps are to be located, the pumps need to be
shielded from the heat. If at all possible it would be better to locate the pumps in a different
location.
- Outside walk-in cooler- moisture can collect in the control cover and swell poppet seals causing
the pump to fail. The cooler temperature causes the viscosity of the product to increase making the
pump to work harder to move the same amount of syrup.
- In ventilated areas only - high concentrations of CO
2
can be fatal, since it will displace oxygen
from non-ventilated areas. If CO
2
operated BIB pumps are placed in a confined area (such as a
basement, closet, cooler box, etc.), exhaust fans capable of changing the room air on a continuous
basis should be used. Another option is to manifold the exhaust ports to the outside.
Guidelines
1. Mount pump with outlet on top at higher or
same level as BIB This allows any air on the
BIB (inlet) side of the pump to float up to the
pump and pass through the system. Creating
an installation which avoids trapping air,
preventing service calls.
2. Inlet Side - Use only 3/8" I.D. (10mm) Tygon
or equivalent tubing with a minimum of 1/8"
(3.2mm) inch wall. Due to the limited vacuum
the maximum inlet tubing length is 10 ft.
(3m). Within that distance, a maximum of 5
ft. (1.5 m) vertical lift is permitted.
(Note:
When an ASV is used, the maximum vertical
lift will be reduced to 3 ft. (1 m).)
3. Label all lines and pumps. To ensure proper
delivery of syrup to the dispenser, all lines
should be tied-down using tie-wraps in their
proper location and clearly labeled. Attention
to detail will prevent accidental mixing of the
flavors during BIB changes and will also
facilitate future servicing.
