PRE-TREATMENT, SURFACE PREPARATION, DEGREASING & CLEANING
After the wash cycle,
the door to the Turbex
process chamber can be
seen rising automatically
to reveal the cleaned
pump components,
which are pulled out
manually onto the
waiting rail-mounted
carriage.
Most components
are washed in a
single cycle, but one
category of parts -
bearing housings -
require two. They
have to be rinsed,
hence the need for
a second water tank,
so the process takes
a little longer.
Component
cleanliness
is essential
to ensure
reliability of
assembled
pumps.

Lawrence
Bradbury, Director of
Engineering at Selwood commented, “Even though we were
impressed with the original Turbex machines, which had given two
decades of good service, before replacing them we looked around
at cleaning equipment on the market to see what was available.
“We took a batch of dirty castings to the Turbex technical centre in
Alton, where their staff carried out a demonstration in a similar
AC-1.7. The parts came out perfectly clean in a cycle time of just
under 10 minutes, so we took the decision there and then to invest
in this type of equipment.”

As part of the deal, Turbex also supplied a second washing machine,
a CL-800, for which the two old aqueous rotating-drum machines
were part exchanged. This equipment is used for processing smaller
items that go into Selwood’s products, such as air pump components.
