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).

Reaction Time: Q&A with Jim Abbott, Market Manager, Julabo USA, Inc.

PITTCON mascot, Pete Con, standing beside the Julabo reactorNot too long ago, while attending the PITTCON show in Atlanta, Georgia, we came across a unique and eye-catching exhibitor system – a special reactor manufactured by Julabo USA, Inc. featuring two KNF SIMDOS® liquid metering pumps transferring fluids to and from the reactor vessel. The machine is quite intriguing on its own; however, after having noticed the two KNF liquid diaphragm pumps, we contacted Jim Abbot, Market Manager, from Julabo USA, Inc. to learn more about the company’s impressive reactor.

1. Overall, what is the purpose of this reactor, what exactly does it do? Does it have an official name?

“We typically just refer to the small reactors of 100mL to 5L size as ‘bench scale’ or ’bench top reactor’, and the 10L to 100L sizes as ’kilo-scale pilot plant reactors’. Systems are available in both glass and stainless steel. Also, we are proud to be the US distributor of Berghof high pressure reactor systems – these have a ton of applications which they are used for but typical uses include: pharma, bio-pharma, plastics, paints, polymers, adhesives, petrochemical, energy, and most recently cannabis. The reactors are primarily used in mixing applications but with add-on features they can be easily equipped for various distillation methods such as: refluxing, short path and fractional distillation. All of our units are automation capable and can be easily controlled using our PC or PLC based AUTOReactor™ control and data logging packages.”

2. What is the function of the two KNF SIMDOS® pumps used within the Julabo reactor?

SIMDOS_Pumps_2 SIMDOS_pumps_1“We use the KNF pumps to control liquid additions or product sampling. The KNF SIMDOS pumps are used, specifically, because of their high quality, reliability, and automation capability. The pumps are connected to our PC or PLC based AUTOReactor™ control and data logging packages which allows users to program and control the process quite effectively and efficiently.”

3. I noticed that the reactor uses both KNF SIMDOS 10, and SIMDOS 02 pumps. Is there a reason why two different KNF SIMDOS pump types were selected?

“We displayed both [pumps] on [our demo] system, but typically we use the SIMDOS 02 on the bench scale reactors, while the SIMDOS 10 is used on the kilo-scale reactors. This is because of their different delivery rates as associated with the scale of the process, but quite often these are used interchangeably across both platforms.”

4. Is there any particular reason that compelled the system’s designer to choose KNF pumps over other dosing pumps from other pump manufacturers?

“We (Julabo) have had a long relationship with KNF both in the USA, and around the world. Moreover, we know without a doubt that KNF has the same principals as JULABO as far as delivering high-quality, reliable products.”

5. Will the Julabo reactor(s) be featured at the ACS tradeshow next week?

“Yes it will; we plan to display it again with the [KNF SIMDOS] pumps in a different configuration but always taking front stage, hand-in-hand with the JULABO products.”

6. Would you like to share any additional facts, or interesting notes regarding this system?

“We are devoted to offering our expertise in temperature control and reaction systems to our customers. Likewise, we are dedicated to providing solutions, from the inception of a process, through scale-up, and into manufacturing. One of the key factors is we design all of our systems with the utmost flexibility so as processes change, and companies grow we to can change and grow together with them.”

Julabo will be exhibiting at the upcoming ACS tradeshow in Philadelphia on August 21-23, 2016. If you will be attending the show, then be sure to check out Julabo’s incredible reactor system(s) incorporating KNF SIMDOS dosing/metering pumps. Also, don’t forget to visit KNF booth #1626 to see our latest laboratory technology, including: SIMDOS 10 and SIMDOS 02 liquid metering/dosing pumps, LABOPORT diaphragm vacuum pumps, LIQUIPORT liquid transfer pumps, the versatile VC 900 vacuum controller, and KNF’s award-winning RC 900 rotary evaporator.

Enhanced Line of Liquid Laboratory Pumps

It’s day two here at #pittcon15 in New Orleans. If you are here at the conference and have not yet had a chance to stop by KNF booth #2211, please plan to do so. One of our features at this year’s show is the recently enhanced line of SIMDOS 10 liquid laboratory pumps.

KNF's SIMDOS 10 liquid laboratory pump

SIMDOS 10 pumps are ideal for metering and dosing applications in a number of professional and academic fields, including: chemistry, pharmaceutical, food research, and polymers, to name a few. SIMDOS 10 pumps offer lab personnel the ability to transfer liquids (up to 500 centistokes*) at flow rates of 1-100 mL/min, with dose volumes from 1 mL to 999 mL.

“While the SIMDOS 10 and SIMDOS 02 pumps can move liquids quickly and accurately, their real strengths are configuration and control options which can be matched to a user’s automation requirements and/or chemical profile” said Dan McDougall, Senior Manager of Laboratory Products at KNF. Indeed the SIMDOS pumps are designed to allow for convenient control of lab metering/dosing tasks which may be repetitive and redundant.

For example, new to this latest version of the SIMDOS 10 is a Cycle Metering Mode. “Say you’re performing an automated fill of vials on a conveyor belt…”, explains MacDougall. “You can program the SIMDOS to dispense a discrete volume into each vial with set pause durations in-between.” This new feature allows the user to set the number of cycles, the pause duration, and the dosing volume.

In addition to the added convenience of the Cycle Metering Mode, there are a few new control type options now available for the  SIMDOS 10. First, the SIMDOS 10 is now available in an RCP-version, which includes a RS 232 interface, enabling ASCII character control of virtually all pump functions, plus the ability to use programmable lab control software such as LABVIEW, or KNF’s free PC control software (available for download at knfusa.com). Next, an RC-version is available, which includes an RC cable for external control options such as a foot switch, or analog PC control. Finally, the standard S-version of the SIMDOS relies on the manual on-board interface with back-lit display for intuitive, push-button operation.

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
a meeting there, please click on one of the following links:
