Engineers choose KNF Flodos liquid pumps
Wageningen University selects pumps for EU-funded BioMinE project to apply innovative biotechnology-based processes as a sustainable solution in the recovery of metals from ores and waste materials
Martijn Bijmans, of the department of environmental technology, is using Stepdos 08RC diaphragm liquid metering pumps for his research in biological sulphate reduction at low pH He explained: "My research focuses on developing technologies for selective metal recovery from waste and process water from the mining and metallurgical industry, by optimising sulphide production in bioreactors to precipitate insoluble metal sulphides
"I use the Stepdos pumps to feed the reactor with the metal ions and sulphuric acid solution, as well as a KNF Neuberger Laboport N840 diaphragm vacuum pump to recycle the hydrogen gas over the reactors.
"These pumps provide a stable flow and do not need regular calibration. They are also compact and easy to operate, but the main beneficial feature for my work is their chemical resistance; they can withstand even high concentrations of acids that I am using. I have been using KNF pumps for about three years now, and they have been perfect for my applications".
Bijmans concluded: "I have also recommended these pumps to many of my colleagues, because I think KNF is pretty much the standard setter."
When your reputation depends on it...
A Testimonial from Bob Peters, Engineer, EcoChem Analytics
EcoChem Analytics, based in League City, Texas, offers only the highest quality analytical systems for air toxics and complete continuous emissions monitoring systems with their main business in the waste incineration market. Currently they are using UN026ST.11 heated head pumps. The stainless steel and PTFE construction, along with the heated pumping chamber, were selected because, in this field, they are never quite sure what sample gases are going to go through the pumps.
“I have been using KNF pumps for nearly 20 years and they have proven to be extremely reliable with very little maintenance. They helped build our company’s reputation for solid, durable products. I have been approached by competitors with various promises; however, they cannot match the reliability of KNF. Our business is Continuous Emission Monitoring Systems. As the name implies, anything short of continuous-reliable performance damages our reputation. We refuse to take that risk.”

Scientists seek understanding of extraterrestrial life with the aid of KNF
LABOPORT pumps.
Life scientists at the University of North Dakota are using KNF LABOPORT® Diaphragm
Vacuum pumps studying plant growth under conditions approaching the vacuum of outer space.
This research is conducted within the Presidential Initiative for a "New Vision for Space Exploration" to
explore future applications for greenhouses on the moon or other planets.
"KNF LABOPORT® pumps
are a very important technical and engineering component of our laboratory system because they
can provide vacuums or varying amounts of pressure, and maintain those pressure levels precisely,
a necessity in our research," commented Vadim Rygalov, Ph.D., who is Professor and lead scientist
at the University's Department of Space Studies.
"Both portable and easy to operate, KNF pumps are convenient to use by our undergraduate
researchers. We have found them to be reliable as well," continues Dr. Rygalov. "We
have a need for precise pressure and vacuum for long work hours."

Redefine High Performance
...previously we used oil-lubricated pumps, but these needed significant amounts
of maintenance due to corrosive solvents mixing with the oil. We heard that KNF manufactured
a chemically-resistant pump that needed less maintenance...after two years, the LABOPORT pumps
have proved very reliable. In fact, they have lasted three times longer than any other pump
we have used.

Maximize Time and Resources
...we soon noticed that the pumps from other brands were constantly breaking
down but those from KNF were not. Pumps take some abuse in our laboratories and we had to
replace diaphragms and parts of the other pumps almost weekly, but the KNF pumps withstood
everything well and the maintenance on them was easy. The difference between the two was as
clear as night and day...

Choose Clean Technology
...based on conversations with our colleagues in university and industrial research labs,
we learned that KNF pumps had a good reputation, and therefore chose them for our labs...they
have proved to be very quiet, but they have helped us to increase our solvent recovery yield
to more than 98 percent.
Dr. Ken Simolo, Department of Chemistry, University of Rochester
Syncom chooses KNF pumps for chemical
processes
Syncom in Groningen, the Netherlands, a contract researcher for pharmaceutical and chemical companies, has chosen the Liquiport diaphragm pumps from KNF Flodos to use in its laboratories.
"We have been using Liquiport 18RC pumps mainly to load columns for column chromatography and to transfer liquid into reaction vessels," explained Fred Leusink, research chemist group leader and equipment manager at Syncom. "The Liquiport's chemical resistance enables us to use the pumps for a very broad range of applications. They are easy to clean and to swap solvents, and are very easy to use - you just turn a knob to find the right flow rate, without unnecessary screens or displays. They also have an interface for external control which offers the potential to control the pump using an analogue signal."
"We have also been using vacuum pumps from KNF Neuberger for over 10 years, including over 100 each of Laboport SC840 and N811 units. Every time we expand we get more of the same pumps, because these pumps are reliable, easy to use and are suitable for many of our applications." Leusink concluded: "KNF's service and support are excellent, and we would definitely go back for more of their pumps in the future."
