MAXIMUM HORIZONTAL TUBING
LENGTHS
BY
VISCOSITY
Distances shown are intended as a guideline
only. (cPs.=Centipose)
Distances shown are the results of tests conducted
at 70°F [21°C] ambient with a static pressure of 85
psi. [5.8 bar] to the pump. All distances assume a
dynamic pressure of 35 psi. [2.38 bar] at the
dispenser to maintain brix.

Feet:
Take 1
%
of 500 ft.
(500 x 1% )
= 5. Which then is multiplied by
the 22 ft. vertical,
(22 x 5)
= 110 ft.
Subtract this product from
the 500 ft.
(500 - 110)
= 390
.
The results indicate a 390 ft. tubing
run
(horz./vert.)
is possible, while the example only requires a
distance of 370 ft.
Meters:
Take 3

(152 x 3%)
= 4.56. Which then is multiplied by
the 6.7

vertical,
(4.56 x 6.7)
= 30.5

. Subtract this product from
the 152
M
(152 - 30.5)
= 121.5. The results indicate a 121.5

is possible, while the example only requires
a distance of 113

.
NOT E:
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
SHURflo Vacuum Regulator.
PUMPS IN SERIES FOR LONG DISTANCES
Long tubing runs or high vertical lift can be achieved by installing
pumps in series. Standard SHURflo Beverage
pumps are not designed to have positive
pressure on the inlet side. The SHURflo
Vacuum Regulating Valve
(VRV)
allows the
pump to receive liquid from a pressurized
source. By positioning a VRV at the inlet of the secondary pump,
incoming pressure is reduced to zero, permitting syrup to be drawn in under vacuum.
SHURflo can recommend several other methods to meet the requirements for a particular installation,
including Pressurized Inlet Pumps or Accumulators. Contact SHURflo for more information.
INSTALLATION GUIDELINES
•
As indicated on the pump, the outlet port is to be mounted up.
•
Pumps are to be mounted at the same level or higher than the B-I-B. The best choice is to have the
pump above the B-I-B.
•

clear, NSF listed vacuum tubing from the B-I-B to the pump.
•
Inlet tubing should not have excessive length. Tubing that is allowed to drape down can trap air in the B-I-B creating a
potential for pump "sold-out" problems.
•
If plumbing multiple B-I-B’s to a pump, B-I-B's should be
"Teed"
side-by-side
horizontally, rather than
one on top of the other
(vertically)
.
•

tubing from the pump to the dispenser should be high pressure rated and NSF listed. Consult "Pumping
