Mechanical Technology — September 2016
A
Brubin BA CIP (Cleaning in Pro-
cess) hose pump was displayed
at the company’s stand in Hall
6, making it a first for South
frican audiences.
“So far, the international success of
this pump design has seen over
€
1-mil-
lion being secured in investment,”
says Brubin general manager, Hannes
Liebenberg, who highlights that these
pumps use collapsible shoe technology,
which allows the hose to be
opened for in process
cleaning.
With substantial developments underway, Brubin pumps, which forms part
of Letaba pumps, showcased a number of innovative products at Electra
Mining 2016.
The Brubin BA
CIP (Cleaning in
Process) hose
pump features
collapsible shoes,
which open the hose
completely to allow air
or water to be passed
through for easy
cleaning.
Brubin pump innovations
on show
Pumping action is achieved by com-
pression of a circular loop of elastomeric
hose with two opposed rotating shoes.
The rotational motion forces fluid in the
hose to move ahead of each shoe.
The pump housing is partially filled
with lubricant, aiding smooth running
of the shoes on the hose. Because the
inside of the hose and inserts are the
only parts in contact with fluid, aggres-
sive and contaminated fluids can be
pumped – and due to the incorporation
of CIP Technology, these fluids can be
successfully flushed.
The moment the shoes are reversed,
they collapse, which unblocks the entire
hose. “By opening the hose completely,
air or water can pass through freely,
making the hose easy to clean,” says
Liebenberg.
On a standard pump, users would
have to open the unit and remove the
shoes for cleaning, which takes about
eight hours on a large pump. “This new
design saves time, since users do not
need to open up, pull apart, or drain the
pump as with the standard hose pump
design,” he points out.
Another innovation from Brubin
showcased at Electra Mining was the
Brubin Magnetic Drive Pumps (Mag
Drive). “These are the future of chemi-
cal pumping,” says Letaba Pumps MD,
John Vass. “Our Brubin Mag Drives are
being supplied to the likes of Denel and
Sasol because of their reliability and
international support,” he adds.
The Brubin range of Mag Drives is
built in South Africa and has an already
impressive footprint in the industry. “I
believe these represent the future of
pumping when it comes to clear acids.
In the USA, over 50% of clear acid ap-
plications use Mag Drives,” adds the
Letaba Pumps’ MD.
Vass highlights that Mag Drive pumps
don’t require mechanical seals or gland
packing “because there is no risk of
leaks”. The fluid in the pump is hermeti-
cally contained, with transmission being
accomplished via coupled internal and
external magnets.
