User Success Stories: Realized continuous and stable liquid delivery of trace amounts!
Liquid control technology incorporating requests from research and development sites.
Chemical Manufacturer S has advanced overseas, but development competition intensified due to the entry of newly emerging countries. As a result, high value added product development was required.
Task:
-Results of selecting pumps with a priority on usability…
In the R&D department of Company S, it was necessary to add a fresh solution to the column at
a rate of 3mL/min in order to evaluate various chemicals under development. So Mr. H, who was
in charge, decided to use the peristaltic pump which was in the laboratory first because he was
familiar with using it day to day and it is excellent with regards to maintainability. Also, from the
point of frequently changing the liquids, the pump seemed optimal because he just had to replace
the tube with a new one.
However, due to the structure of the pump, since it transfers liquid by squeezing the tube with a
roller, the instantaneous flow rate was not stable. In addition, as the tube was used it began to lose
strength and became deformed, the flow rate dropped considerably, and they were not able to get the
results that they expected.
“If it is not possible to achieve stable liquid feeding continuously…” Mr. H felt flustered.
-Frequent replacement is necessary due to concerns about damage to used parts.
Also, when they were using a peristaltic pump, they had a bitter experience where the tube broke and
the chemical leaked. Since then, in order to avoid the risk of the tube deforming or rupturing during the
experiment, they had to replace the tubes very frequently. “I cannot find a pump that can be used stably
with peace of mind for a long period of time…” Mr. H was stuck.
-Issue Points
・ In order to maintain a constant flow rate of 3mL/min, it was necessary to have a pump with a
stable flow even during continuous, long-term flow, repeated operations.
・ In order to prevent damage to the parts, frequent replacement of the parts had to be done.
・ There is no easy to handle pump like the peristaltic pump. (He also wanted to eliminate the time
and effort spent on setting the pump and replacing parts.)
-Points Resolved with our Q Series Pump
・ The new pump was able to stably deliver a constant amount (3mL/min) of chemicals at all times,
and was also excellent in respect to ease of use and maintenance.
・ There were no concerns about damage to used parts, and they were able to use it for long
periods of time with confidence.
・ There are less consumable parts, so there is no need for frequent replacement of parts, and since
it can used repeatedly by disassembling and cleaning the liquid-end parts, the running costs
could also be reduced.
-Performance that has cleared more than 20 field tests.
Mr. H recalled his previous correspondence with Tacmina and decided to consult with us about this
case.
During the consultation with the Tacmina sales associate, he asked, “Do you happen to have a pump
capable of supplying constant, trace amounts with superior maintainability or usability?” He was then
introduced to our Smoothflow Q Series Pump for minute amount injections. This pump was developed
after hearing many requests and demands from researchers who were performing similar tasks and
listening to the opinions of customers who conducted actual liquid tests with the pump. In addition,
this Q Series Pump was created as a result of field tests with 20 companies using Tacmina’s long-
standing technological capabilities.
-Speed up Development and Reduce Costs!
In response to this consultation, Company S decided to install a Smoothflow Q Series Pump on a
trial basis.
“When I actually used the pump, I understood that the performance is even better than what I heard
during the explanation. The Smoothflow Q Series Pump is a diaphragm pump equipped with a high-
performance motor, capable of stably transferring a set flow rate will very little fluctuations in the flow
rate over a long period of time. Also, since there are no rubbing parts like a peristaltic pump, there were
no concerns that the tube will rupture, and it was no longer necessary to frequently replace
consumable parts. Furthermore, in regards to ease of maintenance as well, it was easy to replace the
wetted parts, so it became easier to change out the liquid. Also, since it can be disassembled and
cleaned very simply, we could reuse the same parts for much longer.”
“Due to stable, continuous feeding of liquids, the efficiency of our R&D department has improved
greatly which has drastically reduced costs. When I hear stories from my fellow researchers, the simple
setting and operation functions seem to be the most popular and are making our lives much easier,”
Mr. H said with a smile.
