Any time you lose containment, you have an issue that can spiral out of control.
“I was replacing the pumps once or twice
a year because they kept breaking down,
delivered imprecise amounts, and were
not designed as completely self-contained,
sealed systems,” says Francisco.
After considerable research online,
Francisco decided to utilize a sealed
chemical pump system from Goat Throat.
“I consider using [the] pumps a ‘best
practice’ technique because the barrels
remain upright and the entire system
is sealed so there is never an issue with
exposure or VOCs when transferring
chemicals,” says Francisco.
According to Francisco, the sealed
pump system is intuitive to use because
it operates like a beer tap. “Just pump the
plunger a few times, open the spigot and
dispense. You have full control over how
much is dispensed — even the tiniest
amounts — or you can leave it open for
a continuous flow. It delivers the precise
Francisco adds that the pumps are built
for longevity. Over the past 11 years, he
estimates that his company has saved thou-
sands of dollars by eliminating the cost of
replacement pumps. “I’ve only replaced
one of our three pumps over that time due
to constant use, and we could have used it
longer,” says Francisco.
Allergy Laboratories Inc., a FDA
licensed pharmaceutical manufacturer
of biological extracts for the diagnostic
testing and therapeutic treatment of
allergies, also uses a sealed pump system
to transfer acetone from 55 gallon drums
to 1 gallon containers for a variety of
According to Charles Cheek, facility
manager for Allergy Laboratories, the
pharmaceutical chemical delivery process must be very clean and no foreign
material can be introduced into the acetone.
Because acetone is highly flammable,
he was concerned about using an electric
pump that could potentially create a
spark. As a result, he decided to purchase
a pump that had no electrical or moving
parts that could create a hazard.
“We’ve found [the] pumps to be a much
safer way to transport chemical liquids,”
says Cheek, who utilizes a pneumatic
adaptor accessory to supply pressure via
in-house compressed air. “There is no
spillage, splatter, overpouring, leaking, or
VOCs because the system is self-contained.
There is no sprayback and we do not get
chemicals on our hands. It is a nice, clean
Besides enhancing safety, Cheek says a
sealed system can prevent loss of expen-
sive chemicals like acetone. “I haven’t
lost any product due to the pumps. They
eliminate evaporation, do not leak or
drip and I can adjust the flow to get the
exact amount I need without spilling or
Cheek says he also utilizes a pump to
transfer comprehensive boiler water treat-
ment solution to mitigate scale and cor-
rosion of the boiler system. Previously, he
had to fill a glass beaker with the chemical,
climb a ladder, and pour the chemicals into
the top of the tank.
Now, that work is performed with the
help of the pump and 6-ft. extension
hose accessory to efficiently deliver the
“Every time inspectors come in, they
say we have the cleanest boiler they have
seen,” says Cheek. “With this chemical
transfer system, I’m able to transfer
exactly what I need to get the job done.”
