KNF LAUNCHES NEW COMPACT HIGH-FLOW GAS PUMP

NMP830.1.2 HP from KNF

KNF has introduced new micro gas pump NMP830 HP for OEM customers. This new diaphragm pump offers outstanding high flow, pressure, and suction performance in a compact size. It is ideal for medical therapy, monitoring, and reprographic applications.

Compact NMP830 HP measures just 31mm (1.25”) in width. Yet it produces free flow up to 5.5 L/min with a single head design and to 10 L/min with a dual head. Furthermore, this pump produces best-in-class pressure of up to 3.0 bar g (43.5 psig) and vacuum down to 50 mbar absolute (28.4 inHg).*

The new NMP830 HP is an extension of KNF’s NMP series. This latest addition to the line offers a 33 – 44% increase in flow-to-size ratio compared to existing NMP850 and NMP830 models, respectively. Vacuum and pressure performance are also significantly improved at a comparatively smaller size and lower weight.

Thanks to its compact size, high performance, and quiet operation, the NMP 830 HP pump is particularly well-suited for use in patient monitoring, wound and compression therapy, and respiratory care devices. Additional applications that will benefit from the pump’s features include environmental and security monitors, inkjet printing and color printers/plotters, lab equipment, fuel cell technology, and more.

Available with brushed and 2- or 4-wire brushless DC motors. Standard offerings include EPDM and PPS wetted components. All KNF pumps are engineered for success by optimizing pump solutions to meet customer’s specific requirements.

New Flow-Tight, Diaphragm Liquid Transfer Pump Prevents Uncontrolled Flow

New, FL 10 Diaphragm Liquid Transfer Pump Prevents Uncontrolled Flow

KNF’s newest liquid transfer pump, the FL 10, is leak-tight in both directions, preventing uncontrolled flow and back-flow of liquid media when not in use. The latest addition to KNF’s extensive line of diaphragm liquid transfer pumps, the FL 10 offers many advanced features, and provides a considerable advantages over similar competitive products.

Leak-tight Diaphragm Liquid Transfer Pump

Featuring a solenoid-drive, and leak-tight valve technology, the compact FL 10 liquid transfer pump displaces fluid at a flow rate of 0 – 100 mL/min. Additionally, a signal frequency modulation feature enables quick and easy flow rate adjustments, saving time and money. Finally, like all KNF diaphragm liquid handling pumps, the FL 10 is self-priming, dry-run safe, and maintenance-free – offering outstanding performance longevity and an extraordinarily long service life (10,000 hours or 1.8 billion strokes).

Pumping Above Our Weight Class

NMP 03 Micro Gas Pump
The newly introduced ultra-small, portable device pump — weighing only 11g and measuring just 12.9 mm x 24.2 mm — delivers very consistent, linear transfer up to 500 mL/min.

In addition to ultra-small size and wide flow rate range, the NMP 03 offers a long service life, outstanding efficiency, leak tightness, and quiet, low-vibration operation. Typical portable device applications, for which the NMP 03 micro gas pump is very well suited, include: emissions measurement and gas analyzers; patient monitoring; capnography; negative pressure wound therapy; ion-mobility spectrometry (trace detection); drugs and explosives detection; handheld pipette/dosing; and print-head meniscus control.

The NMP 03 offers a wide operating temperature range of -20 °C – +60 °C (environment and gas) thereby making it well-suited for outdoor use and applications involving hot or cold gases. Plus, like other KNF micro gas pumps, the new NMP 03 features a modular system which can be configured to match your specific requirements.

KNF Associates Discuss MedTech Pump Design Trends with MDDI

Pumps for Medical TechnologyThe following excerpt is from the MDDI article, “Pump Designs Flow Toward Smaller Sizes“.


As medical devices require smaller pumps that fulfill rigorous design requirements, the relationship between OEMs and suppliers is shifting.

A medical device that manages the movement of a gas or a fluid relies on a pump to carry out the application. Advances in technology enable pump suppliers to provide pumps capable of addressing increasingly complex medical device requirements. But industry pressures are also changing the nature of the relationship between OEMs and their suppliers.

At one time, medical device companies looked at suppliers simply as a way to outsource work and reduce costs, said Dave Vanderbeck, business development manager for Trenton, NJ-based KNF Neuberger. While suppliers can help OEMs reduce their costs, Vanderbeck increasingly now sees OEMs turning to their pump suppliers for design expertise.

If you happen to be in Connecticut over the next few months, check out the “Art in Nanochemistry” exhibit at the Stevens Gallery of Homer Babbidge Library at UConn. The exhibit, which runs through June 15th, showcases a collection of photomicrograph images showing objects at a near-billion magnification.

Thanks to the imagery captured by high power electron and/or optical microscopes, Professor Challa Vijaya Kumar—head of UConn’s Divisions of Physical and Biological Chemistry—and his Ph.D. students, have captured natural materials on a nano-level. The results yielded visually-engaging images that look right at home when displayed as framed art in a gallery setting.

Also on display is KNF’s RC 900 rotary evaporator. We like to think the form and function behind the RC 900 displays its own artistry, although, in this case it was selected to be part of this nano-scale themed exhibit to highlight rotary evaporation as an important laboratory tool for small molecule synthesis.

According to the University of Connecticut, the exhibit “is a collection of electron micrographs of nanomaterials from Dr. Kumar’s research group, created with support from the National Science Foundation, works of his colleagues at UConn, and also from the Materials Research Society Art-in-Chemistry annual competitions. Dr. Kumar and his group are investigating how these protein-DNA nanomaterials they create in the lab can be applied in enzyme fuel cells, DNA-solar cells, and neuroprosthesis for spinal cord repair.”

MD&M East: OEM Pumps Support Medical Design Advances

By: Eric Wilson, OEM Senior Sales Manager

The first half of the year has flown by, and we’re thrilled our pumps continue to be relied on in truly innovative applications. We’re equally excited by the recent turnout at MD&M East, where current and potential customers, friends, students and industry pros were able to get a first-hand look at our array of OEM pumps and technologies for medical devices.

MD&M shows have always been an excellent opportunity to keep up-to-speed on current medical device trends, and this latest stop on the  tour in Philadelphia was no exception. It was fantastic to see such a noticeable uptick in booth traffic, especially as the crowd was primed to find technologies supporting the continual drive toward miniaturization. Simultaneously, we continued to see a growing trend of stateside  medical device manufacturers outsourcing design and component sourcing. This was not overly surprising to KNF, as we’ve been called on to  design or augment liquid, air and gas transfer solutions for shrinking equipment for quite some time now. However, our team of  engineers was excited to demonstrate some of KNF’s latest and greatest pumps that are extremely capable of high pressure transfer — despite the need for ever-smaller footprints.

Our Pump Projects stress engineer-to-engineer communication, and shows such as MD&M East offer the opportunity to start—or continue— the conversation. As we’ve learned, communication about application needs often leads to more than just an optimized pump. It presents an opportunity to assist engineers better achieve the overall design objectives of the device. The beauty of a trade show is that we have a bevy of  engineers ready and available with an assortment of pumps, components, datasheets, etc. at our fingertips to show-and-tell our way through any discussion.

To learn more about our full line of OEM liquid, air and gas pumps, or to view our upcoming tradeshow schedule, visit www.knfusa.com. And don’t forget to drop by and say hi at the next show.
