pump with a test motor. “Let’s drop this in the tank
and see if the wet-end is still functioning”. The name
plate is unreadable so we have to find another way
to determine the pump’s capacity. “How long does
it take to fill the tanks normally?”, I ask. “Around 6
hours”, is the response. Ok, that gives us 40l/min.
Now the head (pressure) capability. Counting the
stages of the pump gives us a starting point. The
guys in the shop run the pump while we get some
curves to check the performance against. The lack
of performance quickly becomes obvious as the
unit is put through its passes on the rig. The wetend seems to be worn and a teardown confirms the
diagnoses. Up-thrust damage is evident and with
curve in hand I ask how deep the hole is seeing
that the pump they have been supplied with can
do a 120m lift. The two old guys look at each other
and concur that the pump is hanging at a depth
of 140m. “Mmm…….and the water level?” “Oh no,
that is around 8m from ground level. I measured
that myself with some rope and a spanner”, John
answers. This doesn’t make sense and I suspect
that once again someone has selected a pump not

suited for the application.
A new pump combo is selected by the team and
assembled. Joining kit, motor cooling sleeve,
pressure gauge, the works. Smiles all round
as I meet up with them in the sales office. “My
goodness, we even got a healthy discount!” John
smiles, obviously glad about the decision to come
to us. “Pensioner Tuesday”, comments the Internal
Sales Crew Leader. “You guys get bus fares at half
price and free coffee on Wednesdays at the mall,
so dammed if we don’t also offer some added value
to old folks.” And everyone joins in the light-hearted
moment. After a few electrical connection drawings
and advice on phase balancing to the sparky, the
guys are off.
A later message from the village is that all is well
and the set is working smoothly…..it seems that
even a pump company like AQS can bring joy to
people over this festive season.
