The single air valves are designed to be installed on either side of a
single pump. A bracket at the bottom is inverted and the air supply
lines are rearranged to accomplish this. Instructions for mounting the
valve on either side are provided with the valve assembly, and are also
available at www.teledyneisco.com. The single valve assembly allows
the pump to continuously operate, but the fluid flow is interrupted
when the cylinder becomes empty and the pump refills. Delivery
resumes once the cylinder is refilled.
The dual air valve packages are installed between two pumps and
provide continuous flow with minimal interruption. When the deliv-
ering pump approaches empty, the other pump gradually takes over
fluid delivery allowing the first pump to refill. When the second pump
approaches empty, the first pump gradually takes over fluid delivery
allowing the second pump to refill. This cycle repeats continuously
until the fluid supply reservoir is empty or until the user (or external
programmed control) stops the pump.
Except for the 500xv, all SyriXus series pumps are available with
either single or dual air valves. Because of its specific purpose, the
500xv is only available with the dual air valve package.
