KNF Introduces FP 400 Low Pulsation Diaphragm Pump

New product is designed for recirculation applications in a diverse set of markets

The FP 400 is a next-generation diaphragm pump from KNF. It combines the traditional advantages of diaphragm pump technology — self priming, the ability to run dry, and long, maintenance-free lifetime under continuous-operation conditions — with a pulsation level comparable to gear pumps.

FP400_front

Pulsation for new FP 400 is less than 150 mbar. Levels far below this are achievable, depending on system tubing hardness, tubing inside diameter, and flow path length/configuration. The pump delivers up to 5 L/min of liquid at back pressures to 15 psi, with complete linear control of flow between 10% and 100% of the nominal flow rate. Pump flow is fully stable with fluid viscosities ranging between 1 and 150 cSt. The pump handles viscosities up to 500 cSt with some flow rate reduction.

KNF designed the FP 400 specifically to provide gentle, low-shear conveyance of sensitive media. Other strengths of this innovative new pump include very low vibration, a noise level below 55 dBA, chemically resistant flow path material options for use with aggressive media, and an IP65 protection rating.

The many benefits of FP 400 make it particularly well suited for recirculation applications in a diverse set of markets, including:

  • Inkjet Printing: UV, water-based, and solvent ink recirculation to prevent pigment precipitation; ink temperature management; and meniscus control. Glaze, varnish, and hot-melt recirculation. Major global printer and ink manufacturers have already tested the FP 400 intensively for 18 months, raising much interest.
  • Medical Device: Temperature management, including aesthetic laser cooling systems.
  • Semiconductor: Temperature management/cooling, particularly in systems with sensors sensitive to pulsation.
  • Fuel Cells: Fuel recirculation and membrane hydration.

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.

The Right Pump to Meet Your Continuous Ink-jet Printing Requirements

Application Note: OEMAs the continuous ink-jet (CIJ) printing industry evolves, KNF remains a driving force behind the change from yesterday’s peristaltic and gear driven pumps, to today’s more efficient diaphragm pumps. In fact, KNF is well positioned to serve this industry, thanks to our CIJ applications knowledge and selection of readily-optimized liquid and gas handling diaphragm pumps.

Diaphragm pumps overcome common problems inherent with the use of peristaltic and gear pumps in CIJ applications. Peristaltic pumps have short tube life leading to maintenance issues or messy clean-up, while gear pumps have issues including performance decay, shed particles, high cost, and they cannot run dry. In contrast, our diaphragm pumps provide a greatly extended performance life, lower cost operation, leak-tightness, robust chemical resistance, the ability to handle challenging inks, and our liquid pumps are self-priming and can run wet or dry. In addition, KNF diaphragm pumps can include features such as logic-controlled brushless DC motors, special electrical connections and mounting plates, and dampeners for applications sensitive to pulsation.
