D-Series and HL-Series Syringe
Pump Controller Versions

How to Distinguish Between Versions

Overview

The D-Series and HL/HLf-Series Syringe Pump
Controller designs have undergone several updates.
While old or new controllers work with ISCO pumps,
some operating and maintenance procedures for the
current controller are different from those for the
legacy controller. To ensure that you are following
the correct procedures, you must know which
controller you are using.

Where procedural differences o

Pump Technical Bulletins available on our web site

“current” controller versions.

a different user manual than pump systems using

before servicing or operation if the controller version
is in question.
