4 Description of function
16 Pump Combinations Operation Manual, Version E
The use of two pump modules A and B enables
the formation of a binary gradient. The solvents
enter the pump heads via the suction tubing
(input). The FEP tubing guide the solvents to the
mixing chamber with integrated pressure sensor
and from there via the injection system on to the
column via the pressure tubing (output).
The Pump Manager C-615 regulates the flow
rate of the pump modules A and B and monitors
the current pressure. The maximum pressure
for Pump Module C-601 is 10 bar and for Pump
Module C-605 50 bar. In addition, a variety of
programs and settings enables to select the flow
rate of the solvent, the pressure, time and gradi-
ent of the solvents.

4.2 Operative range of the pump systems
The Pump Module C-601 pumps 2.5 to 250 ml/min of solvent at a maximum pressure of 10 bar. The
Pump Module C-605 pumps 2.5 to 250 ml/min of solvent at a maximum of 50 bar.
ATTENTION
Do not connect the Pump Module C-605 to the Pump Controller C-610, otherwise an error message
appears on the display.
If a Pump Manager C-615 or a Control Unit C-620 is used make sure that the same Pump Modules
C-601 or C-605 are used.
