KNF Neuberger gas and liquid pumps handle many clinical diagnostics instrument tasks, including: washing, waste handling, metering/dosing, aspiration, degassing/debubbling, fluid transfer and recirculation, vacuum, and pneumatics. New KNF products to be presented are: compact high-flow NMP830 HP, measuring just 1.25” in width yet producing free flow to 10 L/min with best-in-class pressure to 43.5 psig and vacuum down to 28.4 inHg; low pulsation FP 400, combining diaphragm technology advantages — self priming, run-dry ability, and long life — with a pulsation level comparable to gear pumps; and at 4” long, economical swing-piston gas pump NPK 012 is 30% shorter than other models in its performance class, reaching 25.8 inHg with a flowrate to 13.5 L/min, delivering 36 psi continuously and 72 psi intermittently. KNF optimizes pumps to your OEM performance needs, balancing desired controllability, lifetime, and cost. Stop by the KNF booth to consult with an engineer about your next project.

• Need More Flow? KNF Delivers. (May 10, 2019)

   KNF introduces 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 and monitoring 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.

  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.

• Low Pulsation Liquid Diaphragm Pump Introduced (May 10, 2019)

  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.

  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.

• High Flow, Low Pulsation Liquid Diaphragm Pump (May 10, 2019)

  KNF’s new FK 1100 diaphragm liquid pump is one of the most advanced solutions on the market for gentle, low-pulsation flow. The 12 L/min flow rate doubles KNF’s previous maximum for liquid diaphragm pumps. This pump is robust, adjustable, and offered in a variety of application-friendly materials.

  The FK 1100 has only one inlet and one outlet, despite having three diaphragms. These are offset by 120° from each other while connected in parallel, resulting in very low pulsation and minimal shear forces. Intensive testing has proven that the pump easily achieves pulsation values below 200 mbar at the inlet and outlet. This gentle conveyance spares fragile system components and media elements from potential damage.

  The pump has a highly durable design with a die-cast aluminum housing and high-torque motor options that provide continuous operation with up to 87 psig back pressure. Even at this high pressure, the FK 1100 still delivers an impressive 8 L/min.

  This pump is self-priming with a 13.5 inHg suction height. It is also able to run dry which reduces the need for additional equipment, offers more flexibility in planning, and allows for faster and easier system integration.

  Versions are available in a variety of carefully selected materials, such as NSF-certified materials for food applications and chemically resistant elastomers. Customers can also choose between different drives, such as brushless DC or single-phase AC motors. The speed of the brushless DC motor can be controlled using analogue or digital PWM signals, permitting lower flow rates if desired.

  Applications for the FK 1100 include transfer, recirculation, temperature management, and aspiration of liquids in a wide variety of industries.

• Economical, Compact and Lightweight Vacuum/Pressure Pump for Portable Devices (Jul 08, 2019)

  As a partner to equipment manufacturers, KNF introduces a new oil-free swing-piston pump that addresses the demand for a more compact, high performance, and economical solution for portable devices

  At 4" in length, the new NPK 012 is 30% shorter than other models in its performance class. Even more impressive, the new pump’s weight is a light 600 g, under-cutting other models by half.

  Although small, the NPK 012 offers high levels of both vacuum and pressure performance. The vacuum version reaches 25.8 in.Hg (140 mbar abs), has a maximum flow rate of 13.5 L/min, and can deliver 15 psig continuously. The pressure version delivers up to 36 psig (2.5 bar) of continuous positive pressure, and up to 72 psig (5 bar) during intermittent operation. Both versions can start up against the full vacuum and pressure range, and the brushless DC motor provides excellent custom-fit speed control with low energy consumption.

  The great performance-to-size and price-to-size/performance ratios of NPK 012 make it well-suited for a diverse array of medical and clinical diagnostic application tasks, including nebulizing, spraying, drying, and and pneumatic actuating.
