Trade Show Demo Features KNF Micro Vacuum Pump

Throughout the year, we’ve noticed a demonstration unit that caught our attention on the show floors of BIOMEDevice San Jose, SLAS and MD&M West. This demo – created and displayed by AllMotion – highlights the ability of their four-axis controller board, and utilizes a KNF Micro Gas Pump to create vacuum for stacking and unstacking marbles at a dizzying speed. AllMotion is a California-based manufacturer of stepper drives, stepper controllers, servo drives and servo controllers.

The demo illustrates the ability of the AllMotion board to run motors through four axis of movement and calculate the associated trajectories, while simultaneously running the KNF Micro Gas Pump, a vacuum switch, limit switches, and LEDs – all in a perfectly-timed ballet of motion.

KNF Demo to Debut at SLAS 2015

In just a few short days, some of us here at KNF will be leaving for our nation’s capital to attend the 4th annual SLAS Conference and Exhibition, being held from February 8th-10th. We are particularly excited about this year’s SLAS event as we will be unveiling a brand new demonstration at the KNF Neuberger booth (# 1511).

The new KNF demonstration effectively showcases a number of real-world pump applications, including: direct liquid transfer, vacuum aspiration, and pneumatics via 3 unique KNF pumps. When initiated, the demo cycles continuously through three separate stages. Light-up placards provide clarity for the viewer by explicitly stating which of the following processes is being performed in the demo:

KNF Pump Applications Demo

The KNF demo cycles through Vacuum Aspiration, Onboard Pneumatics, & Direct Liquid Transfer.

1) Vacuum Aspiration– The first process (pictured right) shows fluid being aspirated by the suction created from a powerful vacuum pump. You may notice the system’s ability to generate vacuum-over-liquid easily and quickly – this is due to the selection of a pump with a high gas flow rate, and the ability to handle moist gas with slugs of liquid.

2) Onboard Pneumatics– The next stage demonstrates high pneumatic performance in a compact, quiet and energy-efficient manner. The system employs a micro gas pump to pressurize a pneumatic cylinder which, in turn, raises a tube – a similar function to needle aspiration which is performed for various medical applications.

3) Direct Liquid Transfer– The 3rd process demonstrates direct liquid transfer, using a diaphragm liquid pump. Here, direct transfer of liquid media is made possible using a specially-designed, two-headed pump with high self-priming ability, and smooth flow – ideal for demanding, real-world applications, such as direct handling of liquid waste.

While each stage of the demo illustrates a unique application, it’s important to note the commonalities amongst the stages: First, each pump/stage includes chemically-resistant materials, which allow for the transfer of aggressive media. Each pump also utilizes a brushless DC (BLDC) motor. The BLDC motor (available for most KNF pumps) enables more precise speed control, lowers audible noise and vibration, and promotes a longer lifetime of operation. Also, a new KNF Digital Control provides enhanced programmable features over previous analog controllers while promoting consistent performance and reliability. Tested to over 1.6 million on/off cycles and 100,000+ hours in pump life tests, the KNF Digital Controller offers superior performance in demanding applications.


If you’re going to be at SLAS next week please stop by the KNF Neuberger booth (#1511) to check out our new demo, and to learn more about KNF’s range of gas and liquid OEM pumps.

See You At AACC!

NFB 100 liquid diaphragm pumpNFB 100 liquid diaphragm pump with datasheetToday we’re packing up and preparing to send materials to display in the KNF Neuberger booth at AACC 2014, held this year in Chicago on July 29 – 31. Before we lock up the crate, though, we thought we’d take a quick break and mention that we’ll be introducing a brand new liquid diaphragm pump at the AACC show.  With two heads driven by one motor, this pump provides twice the flow and half the pulsation when operated in parallel mode. In the individual mode, two different liquids can be transferred simultaneously by one unit, eliminating the need for a second pump.

Please plan to stop by KNF Neuberger booth #4328 at AACC next week. For more information before the show, or to arrange
