Watson-Marlow SP40 - Manual (Page 17)

DESCRIPTION
14
With rotation in CIP mode the pressing shoes are
retracted one at a time during one full rotation in the
pumping direction.
The pump is not intended to keep running in CIP mode.
When the cleaning procedure is finished, first the cam
(B) has to be repositioned to neutral. After the cam is in
this position, the pump can be started in normal
direction of rotation. The springs will pull the pressing
shoe back to the normal (pumping) position.
Additional remarks:
•
The construction of the rotor and cam
mechanism depends on the rotation direction of
the pump. Refer to section 7.9.
•
After initial assembly, the pump cover cannot be
mounted in another position.
•
To avoid wear to all vital parts, we recommend
following speed limits:
Bredel CIP 40 : 60 rpm
Bredel CIP 50 : 50 rpm
POSITION 3
Caution
Stop the pump after one revolution when
the pump is in CIP mode. Continuous
rotation may cause excessive wear and
damage of the cam mechanism.
A
B
Caution
Do not start the pump before the cam is in
neutral position;
Do not reverse rotation when actuator
(cam) is in active position, this will
seriously damage the cam mechanism.
When the actuator (cam) is in neutral
position, the pump can be reversed as
normal.
