Ensure contaminated pumpheads are not shipped but disposed
of locally according to regulations for contaminated items and
health and safety procedures.
Always isolate the pump from the mains power supply before
changing the pumphead, suction or discharge lines.
It is only possible to fit the pumphead in one orientation with the
arrow pointing upwards.
The pumphead retaining clamps should only be loosened or
tightened by hand.
Note: In this manual we have shown removal and replacement of the left hand
mounted pumphead. Replacing the right hand mounted pumphead is the identical
procedure.
Removing the pumphead

• Ensure that there is no pressure in the pipeline.
• Isolate the pump from the mains power supply.
• Ensure that protective clothing and eye protection are worn if hazardous products
have been pumped.
• Remove input and output connections from the pumphead.
