A SyriXus series continuous flow pumping system consists of two
syringe pumps and a valve accessory package regulated by one con-
troller. This system allows you to continuously deliver liquefied gas or
liquid under Constant Flow or Constant Pressure Mode.
Continuous flow can be used in either of three modes: continuous Con-
stant Pressure, continuous Constant Flow or Receive Mode. These
modes assume positive displacement of the piston, with the exception
of continuous Receive Mode (for detailed information about Receive
Mode, refer to Technical Bulletin
Operation for Receive
In any syringe pump continuous flow system, a flow irregularity
occurs at the time of switchover from one pump module to the other.
This flow irregularity can be measured as a pressure fluctuation.
Teledyne ISCO pressure fluctuation at switchover is ~0.35 bar (at
system backpressures from 6.9 bar to the single-pump maximum).
Before programming continuous flow, appropriate valves must be con-
nected, the pumps must contain fluid, and there must be backpressure
for operation. Specific installation instructions for the valve packages
are supplied with the valve package.
Air valves generally open and close faster and are less prone to error
and component wear, making them suitable for industrial use and
other applications where the system will be constantly running;
however, they require a user-supplied pressurized air source of 80 to
115 psi (5.5 to 7.9 bar).
