KNF NMP015.1.2 Micro-Diaphragm Sampling Pump
with Uniquely Integrated Internal Head Connections
|


|
A new KNF micro diaphragm gas-sampling pump, type NMP015.1.2,
uniquely integrates head connections inside the housing for improved pneumatic
performance in a compact and leak-tight package. This optimized design produces
less pulsation and additionally allows for the housing to be closed and sealed
for significant reduction in audible noise.
The pump ideally suits portable, battery-operated
equipment used in a wide range of OEM applications, including gas sampling, explosives
detection devices, anesthesia systems, and medical analyzers, among others. Among
features, the pump’s elastomeric diaphragm promotes high efficiency and delivers
oil-free operation without any risk of contaminating the sampled gas. Pumps can
be specified either with an ironless core DC motor or with a brushless DC motor
offering longer service life. PEEK housings and pump heads contribute high stiffness
and temperature and chemical resistance. Depending on model, these pumps can
achieve flow rates to 2.1 l/m, vacuum to 650 mbar (11 in. Hg) absolute, and continuous
pressure to 0.6 bar g (9 psig).
All are engineered to perform maintenance-free
with low power requirements and are supplied ready for installation to operate
in any position. Chemically resistant versions are available and pumps can otherwise
be customized to meet particular application demands.

KNF NMS020 Micropump for Air or Gases
Delivers High Efficiency in a Compact Package
|


|
The new KNF NMS020 micropump introduces an efficient and
reliable solution to transfer, evacuate, or compress air or gases for analytical,
medical, and all portable instruments where space is at a premium. This compact
vacuum pump measures 17mm (width) x 31mm (height) x 44m (length), weighs 32g,
and can deliver high-performance flow rates up to 1.8 LPM, vacuum up to 15 in.
Hg, and pressure up to 7.5 psig.

diaphragm that promotes high efficiency and flow and helps the pumped medium
remain pure and contaminant-free. These micropumps enable safe, oil-free operation
without maintenance. Corrosion-resistant wetted parts reinforce their ability
to withstand especially harsh conditions. The pumps are powered by cost-effective
brush DC motors or brushless DC motors where applications demand extended service
life and low EMI/RFI.

New diaphragm vacuum pumps and compressors
feature dynamic mass balancing
|

 

|
KNF Neuberger
announces a new range of diaphragm vacuum pumps that are first
to use their patented dynamic mass balancing mechanism. The dynamic
mass balancing feature of the model N843 and N880 pumps instantly
and automatically compensates for out-of-balance conditions
caused by various pressure loads of gas forces. This results
in extremely smooth running characteristics over the entire operating
range. These new pumps are especially suitable for use as vacuum
roughing pumps used to pump down turbo-molecular pumps. Because
the compression chamber is hermetically sealed from the drive
mechanism of the pump, the medium being handled remains uncontaminated.
Models up to 80 liters per minute with an ultimate end vacuum
capability of 1.5 Torr (29.86 "Hg) with a maximum pressure
of 15 psig are available.

Custom 2-Stage Vacuum Pump and Swing Piston Compressor
|


|
Where independent functions are needed, KNF will match a variety of
pumps together on a common motor to save cost and size. Driven by an electronically
commutated DC (BLDC) motor, this custom pump provides our customer with a vacuum and
pressure source in a remarkably small package for their instrument testing assembly.
The complete pump, motor, and control require
only a simple power connection to the normal 2-wire DC power for operation.
The BLDC controller design includes an available "on-demand" speed control
feature to enable nearly seamless integration into a larger
system. The highly efficient BLDC motor provides the ability
to dramatically reduce the size of the pump-motor package, lower
power usage, and significantly reduce heat radiation and cost.

Compact Deep Vacuum Diaphragm Pump reaches 375 micron (.375 Torr / 0.5
mbar) for Roughing or Backing Applications without Pump Oil
|

 
|
This N813.4ANI vacuum pump is driven by a brushless dc motor that requires
only a simple connection to 2-wire DC power for its operation.
The BLDC controller design includes an available "on-demand" speed control nd logic
on-off feature to enable nearly seamless integration into the larger
system control. In comparison to an AC motor, the highly efficient BLDC motor provides the
ability to dramatically reduce the size of the pump-motor package, lower
power usage, and significantly reduce heat generation.
This exciting
BLDC technology is available in a range of KNF pump sizes from the
compact 50 milliliter/minute through the 30 liter/minute pump models.
Higher performance and chemical resistance versions are also
available. These new BLDC pumps powerfully compliment the industry-leading
range of world-class KNF diaphragm pumps now serving the vacuum
industry worldwide. These pumps are ideal for backing turbo pumps
in corrosive gas RGA, MALDI-TOF, HPLC-MS, or any time your application
demands a quiet, oil-free rough vacuum pump.
