Steel possesses the
strength and structural
integrity to support a 100-
story skyscraper or a mile-
long extension bridge. Yet
the process used to manu-
facture steel is an extremely
delicate one.
One person very familiar
with steel-making intrica-
cies is Wim Brandsema,
director and an owner
of LBTEC INDUfinish, Emmen, The Netherlands. Founded in 1991,
LBTEC INDUfinish supplies systems used in surface-treating steel.
“We currently sell our equipment mainly throughout Europe and we are
starting to pick up business in Northern Africa and the Middle East,” said
Brandsema. “LBTEC INDUfinish specializes in hot-dip galvanizing, par-
ticularly the pre-treatment stage of the hot-dip galvanizing process.”
hottotrotThe pre-treatment that leads to the actual hot-dip galvanizing of steel is
precise and exacting:
• A piece of raw steel is pre-treated with a degreaser to remove any oil and grease from its surface.
• The steel is “pickled” in a hydrochloric acid bath.• The steel is dipped in flux fluid to ensure the zinc will react correctly
with the steel.
• The steel is placed in a melted zinc bath at 450 degrees C (about 840 degrees F); if the previous three steps were not followed properly, the zinc
will not adhere to the raw steel.
• The piece of steel is hot-dip galvanized.LBTEC INDUfinish’s system houses the flux fluid used in the pre-
treatment. The system includes four compartments: the first contains the
flux fluid; the second mixes the flux fluid with certain chemicals to obtain
the correct pH level; the third receives the flux fluid after it passes through a
filter press to en-
sure that any iron
in the flux fluid
is collected, al-
lowing only clean
flux fluid to come
out; and the
fourth gathers the
used flux fluid
before transfer to
the flux-cleaning
unit and back to
the first flux-fluid

tank. The system’s heartbeat is the four individual pumps keeping the flux
fluid flowing amongst the four compartments.
“We began producing these units in 2006 and the most important issue
is that you have to make sure it is not going to be corroded when oper-
ated,” said Brandsema. “Flux fluid
is very aggressive so we have to
have a pump that that will last
at least 10 years. We knew that
to manufacture our products we
would need plastic pumps that
would have to deal with very cor-
rosive fluids like hydrochloric acid.
Steel, carbon steel and stainless
steel aren’t compatible with these
very aggressive fluids, so you need
plastics like PE, PP, PVCs and
PVDF.”
challengesearlyon“An electric-driven, vertical
centrifugal pump for the second
stage lasted only six months,” said
Erik van der Staaij, sales manager
for LBTEC INDUfinish. “At that
point, the engine was rotted away by
the chemistry we were pumping.”

The solid-body, plastic construction of AODD
pumps make them well-suited for handling
aggressive and corrosive fluids used during the
hot-dip galvanizing process for steel, including
flux fluid and hydrochloric acid.
EUROPE Almatec continued
As it happened, the other three pumps contained in the system were solid-
body plastic air-operated double-diaphragm (AODD) pumps from Almatec, Kamp-Lintfort, Germany. In 2008, Almatec became a founding member of the Dover Corp.’s Pump Solution Group, Oakbrook Terrace, Ill.
“We looked at the other three pumps,” said van der Staaij. “We didn’t
see any corrosion, so we mounted another Almatec pump for mixing the
chemical solution and it worked fine. We have never seen any leakage from
the pump or connections, not on the thread or the pump body itself; ev-
erything sits tight.”
Plastic AODD pumps are positive-displacement pumps that have a dia-
phragm in each of their two pumping chambers. These diaphragms are
connected by a shaft so that when the compression stroke takes place in one
chamber, the suction stroke takes place simultaneously in the other. This re-
sults in efficient operation when handling any type of corrosive liquid.
The pump features solid-body design. Typically, construction is of
polyethylene (PE), which offers abrasion-resistance said to be seven times higher than pumps made with polypropylene (PP) — while still having similar chemical-resistance characteristics — and are 1.6 times more du-
rable than stainless-steel pumps.
apumpperformsSolid PE also delivers better sealing, higher static weight, smoother
operation and better torque retention than other popular materials of
construction. For specific applications, E-Series pumps can also be con-
structed of PE, PE conductive, polytetrafluoroethylene Teflon (PTFE) and PTFE conductive. All of the pump’s cylinder valves are constructed
with PTFE; diaphragms are made of ethylene propylene diene monomer
(EPDM), PTFE/EPDM and nitrile butadiene rubber (NBR); and ball

valves are made of EPDM, PTFE, NBR and stainless steel.Since 2006, LBTEC INDUfinish has produced more than 50 flux-fluid
systems used in steel-making applications around the world.
“The first pump from 2006 we overhauled in 2012 and we changed the
membranes, we changed the valves, we changed everything, but there was
no need to change them,” says Brandsema. “It was still running perfectly
with the valves and membranes of 2006, even handling an aggressive fluid.
At the heart of our units you will find Almatec E-Series plastic pumps. We
rely on them, and we would choose nothing else.”
