2.22.2 Function descriptionFunction description
Pump module in general
Depending on the requirements, up to 3 pump modules can be controlled and regu-
lated with one control module.
Pump modules are available in two di󰀨erent versions:
5 mbar ultimate vacuum and 30 m³/h pumping speed or
70 mbar ultimate vacuum and 40 m³/h pumping speed.
Switching on
The vacuum pumping unit and the connected pumping modules are switched on
via the main switch on the control module.
Vacuum pumps
At the heart of each pump module are 2 speed-controlled diaphragm pumps for
vacuum generation. Individual rocker switches on the control module switch the
diaphragm pumps on and o󰀨 individually.
Vacuum pumps can be switched o󰀨, disconnected, and removed individually with-
out a󰀨ecting the vacuum process, e.g., for service or maintenance purposes. Each
individual pump is compact and can be removed and maintained by just one per-
son.
A diaphragm pump generates a dry, oil-free vacuum because of the hermetic sepa-
ration between suction chamber and drive. The design of the pump heads and its
unique stability core provides high chemical resistance.
The diaphragm pumps meet the requirements of ATEX equipment category 3 in the
internal, wetted parts area. Applicable for pumping of Ex-mixtures infrequently or
for a short period.
Vacuum control
In the control module, the controller regulates the speed of the diaphragm pumps
and thus the vacuum as needed. The diaphragm pumps only run as fast as neces-
sary.
When a vacuum pump is removed, the speed of the other pumps is automatically
adjusted by the controller.

Description of pump module
Status display for monitoring
The operating status of the vacuum pumps is displayed using the light column, the
status LEDs, and the rocker switches on the front of the control module.
Connections
The following connections are located on the pump module:
Vacuum connection for the process = suction line.
Exhaust gas line with the option of connecting a condensate collection tank
#20745016 at the outlet.
Connection option for gas ballast at the control module.
Suction/pressure distributor with thread for suction-side condensate collection
tank (glass ask in front of maintenance door).
In the case of a vacuum pumping unit with several pumping modules, these are
connected in parallel using the "connection set", each with a common suction line
and exhaust gas line.
