8 MAINTENANCE OF CAM AND ACTUATORS
8.1 Cam assembly
The cam assembly is available in two variants. One for
clockwise (CW) and one for counter-clockwise (CCW)
rotation. The type of variant can be determined by
looking at the mark (A) on the cam as indicated in the
picture.
The CW variant has the label R (right) and the CCW
has the label L (left) engraved in the cam.
For ordering this pre-assembled part please contact
your Bredel representative.
In this manual the definition of clockwise (CW) and
counter clockwise (CCW) pump rotation is based on a
viewing direction from non drive-end (NDE) towards
drive-end (DE). In other words when looking at the
pump front cover.
Warning
Only use original Bredel parts when
maintaining the hose pump. Otherwise
Bredel cannot guarantee correct
functioning of the pump, also see: “Safety”
and “Warranties”.

to change the rotation of the pump. The
