to collect potential liquid, which can
reaching entering the pump.
The Vacuum Regulator allows for
control of the vacuum level between
atmospheric pressure and ultimate
pressure of the pump.

to collect any potential exiting liquid.
The exhaust air is filtered and sound
proof at the same time.
The enables the adjustment of the
air pressure between atmospheric
pressure and maximum overpres-
sure.

Connecting to the electricity supply
The WOB-L
®
Piston Pumps are supplied with complete electrical wiring. It is connected via a
mains connection cable and a power plug. Mains connection cable and plug must comply
with the requirements of the line disconnection devices (current, output).
Motor is provided with a thermal overload protection ex works, protecting the vacuum pump
from damage or destruction, respectively.
WARNING !
Should the user change the electrical connection, for example for fitting into a sys-
tem, then this may only be performed by a electrical specialist under observance of
the accident prevention regulations.
