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
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
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.
• M
tubing length is 10 ft.

(
• 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
•

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