Always isolate the pump from the mains power supply before opening the
guard or performing any positioning, removal or maintenance activity.
There are moving parts inside the pumphead. Before opening the guard or
track, ensure that the following safety directions are followed:
•
Ensure the pump is isolated from the mains power.
•
Ensure that there is no pressure in the pipeline.
•
If a tube failure has occurred, ensure that any fluid in the pumphead
has been allowed to drain to a suitable vessel, container or drain.
•
Ensure that appropriate Personal Protective Equipment (PPE) is worn.
Pumphead installation
A correctly engineered installation will promote the best possible tube life, so please ensure that the
following guidelinesarefollowed:
•
Avoid tight pipeline bends, pipe reducers and excessive lengths of smaller bore tubing than that in
thepumphead, particularly in pipelineson thesuction side.
•
Ensure that connecting pipework and fittings are suitably rated to handle the predicted pipeline
pressure.
•
If rigid pipework comes in close proximity to the pumphead, a drop-out section of pipework will
simplify tube replacement.
