Sandpiper trouble
free in fumed silica
transfer
A resin manufacturer on Brisbane's
south side had to add
fumed silica into a mixing vessel.
As many as ten bags had
to be added into a 2 1/2 metre tall
blending tank where the
contents would be unloaded
through the open manhole.
This material is being used as
a thickening agent for certain
resin products. Although the
bags contain only 5 kilos of
powder, they are very large
due to the low specific gravity
of the fumed silica.
Adding the fumed silica posed
the following problems for the
customer:
- The bags were difficult to
manoeuvre up the vertical
ladder.
- The emptying of the bags
took a long time through the
manhole.
- A lot of powder was wasted
and the operator was exposed
to the fine particles.
The customer looked into numerous
possibilities to solve
the problem, but equipment
such as a complicated vacuum
system was just too expensive.
Visiting the plant and listening
to the problems, Kelair's engineer
suggested a 2" Sandpiper
air-operated double diaphragm
pump.
The set-up involved a 2" aluminium
Sandpiper pump fitted
with Buna-N diaphragm, valve
balls and valve seats.
A non-collapsible plastic hose
was connected to the suction
end and discharge of the
pump.
The suction hose was fitted
with a 1.2 metre long plastic
pipe which could be inserted
through a small opening in the
bag.
The discharge hose was attached
to the outlet of the
pump in order to convey the
powder to the top of the
blending tank, which was fitted
with a camlock fitting.
The diaphragm pump has
been in service for more than
two years on the dry powder
application, with the following
results:
- The emptying of a 5 kilo bag
takes less than 45 seconds.
- The waste is close to zero.
- The operator is working on
the ground and exposure to
the silica is absolute minimum.
Over the past two years the
pump has been completely
trouble-free and has not required
any spare parts.
