tions is KNF's ability to further optimize
pumps to customer needs at any lot size.
The FP 70 is well suited for a wide
range of applications, including medical
technology, inkjet, 3D printing and analytical instruments. It joins a growing line
of KNF smooth flow liquid diaphragm
pumps that now boasts a flowrate range
spanning from 120 ml/min-12.4 l/min.

homogeneity in the insert, the RTC-700
temperature calibrator with the DLC sensor is the ideal solution to ensure these
critical turbine temperature sensors are

(1,022°F-1,292°F) is essential. Any deviation in temperature can result in increased
maintenance, higher risk of a shutdown
and a reduced lifetime.
Turbines use temperature sensors to
monitor the inlet steam to avoid these temperature deviations. However, these sensors may drift over time, so regular calibration is required. Because the temperature
and demand for accuracy are exceptionally
high, finding the right piece of equipment
to calibrate these sensors is challenging.
AMETEK STC has the solution with
its JOFRA RTC Series Reference Temperature Calibrators (FIG. 2). The RTC
temperature calibrator series includes
seven models covering a total range from
-100°C-700°C (-148°F-1,292°F). The
RTC-700 model features a temperature
range from 33°C-700°C (91°F-1,272°F),
allowing it to calibrate steam turbine sensors. In addition to its highly accurate
internal sensors, the RTC temperature
calibrator can be combined with the
patented DLC system to provide perfect
temperature uniformity inside the insert.
It also features an advanced simplicity interface, so learning how to use the calibrator takes just minutes.
With an accuracy of ± 0.29°C, stability to ± 0.02°C, and perfect temperature

With the introduction of FP 70, KNF
further expands its series of smooth flow
liquid pumps (FIG. 3). This product line
combines the low pulsation of a gear or
centrifugal pump with the strengths and
advantages of diaphragm pumps.
The KNF FP 70 delivers up to 850
ml/min while producing up to 29.4 psig
(2 bar) pressure under continuous operation. Thanks to the patented four-point
valves, the KNF FP 70 is reliably selfpriming, even at very low motor speeds.
It also can safely run dry, handles liquid
transfer gently and cleanly, and is available
with chemically resistant flow path materials. The integration of the pulsation
dampening technology eliminates the
need for additional pulsation dampening
elements and tubing when using the KNF
FP 70, thus reducing space requirements
vs. a pump-plus-damper approach.
The versatile FP 70 is available with
a selection of motors to match the functionality and lifetime requirements of
the application: from high-end BLDC to
lower-end DC motors. Depending on the
operating parameters, the high-end BLDC
motor achieves a lifetime of more than
20,000 hr. Furthermore, the parameters of
these motors can be customized at KNF to
dial in the desired control behavior, performance characteristics and pump accuracy.
Additional options include a selection of
hydraulic connections and a variety of flow
path materials, including an NSF foodgrade version. Combined with all these op-

Compact Membrane Systems (CMS),
a pioneer in separations technology, has
developed a new membrane for capturing carbon dioxide (CO2 ) out of flue gas.
This is the third addition to CMS's Optiperm™ product portfolio (after separating olefins from paraffins and upgrading
biogas) and is aimed at reducing greenhouse gas emissions.
Early results show promise, with the
high-flow membrane consistent with a
$20/t cost of carbon capture. These results position Optiperm carbon as more
cost-effective than many alternative CO2
capture methods and in an economically
attractive range for current projects and
incentives. Optiperm carbon will scale up
on CMS' existing Optiperm technology
and manufacturing platform.
With the sustainable energy transition
in motion, it is vital to reduce greenhouse
gas emissions from existing processes in
the short term to continue to produce reliable and affordable power. A majority of
the world still relies on fossil fuel technology for power and coal-fired power plants
account for 30% of global CO2 emissions.
Carbon capture technology allows users to
filter and sequester the CO2 at the source
and reduce emissions by up to 90%. Fouling resistant membranes hold promise for
carbon capture because they can be scaled
to the size of the application and require
lower energy usage and operational cost
than existing carbon capture technologies.
Optiperm carbon is a fluoropolymer
facilitated transport membrane with antifouling properties. The initial lab results
show a permeability of 4000 GPU-6000
GPU, a 3x improvement over the industry
standard. The high GPU and resistance to
fouling are expected to significantly decrease the cost of carbon capture. Work is
continuing to scale up the membrane on
the same spiral wound platform as existing Optiperm products.
