	This new NF25 super-compact liquid pump is the same size as our NF10 model, but features 250% more flow. and a patented valve system that ensures a linear flow-to-motor speed performance for simple dosing applications. An integrated anti-cavitation chamber provides quieter operation and higher flow. It is available with a traditional brush-commutated DC motor, a long-life ironless-core motor or a 4-wire logic controlled, wide variable speed brushless motor, and a variety of wetted materials. Install it in any position, mount it close to your desired pumping function, unlike other larger heavier pumps that require mounting in remote locations and long tubing runs. Self priming, there is no tubing maintenance, it can run dry and has a long lifetime. Perfect for transfer and metering functions in instruments, fuel cells, medical diagnostic analyzers, process samplers, waater treatment, probe washers, and ink-jet printers, and for portable instruments where low current, consumption and reliability are necessary. Contact KNF application engineers for details. Models (.51) built to NSF/ANSI 169 are available. Descriptive NSF flyer:
	Recently announced addition to the KNF liquid pump line is the NF5_DCB-4 transfer and metering pump. It features a long-life, low EMI/RFI premium quality 4-wire brushless dc motor, with integrated logic-controlled variable-speed motor controller. This pump is designed in response to the demands of the medical diagnostic, cleaning, disinfection, and fuel cell OEM designers. Contact KNF application engineers for details. Models (.51) built to NSF/ANSI 169 are available. Descriptive NSF flyer:
	KNF's model NF5 is our smallest liquid diaphragm pump, and only 32 grams in weight. It features extremely quiet operation and a compact size of only 42 mm long. Because of its compact size and low weight, this pump can be mounted anywhere in your equipment, in any position. All KNF liquid pumps are self-priming and can run dry indefinitely. Contact KNF application engineers for details. Models (.51) built to NSF/ANSI 169 are available. NSF flyer:
	KNF's model NF10 and NF11 miniature liquid diaphragm pumps features higher flow, and additional motor options, including AC, DC, BLDC and ironless-core DC. A high-pressure NF1.11 model is also available. These pumps are excellent for use in ink-jet printers and chemical analyzers. Model NF10TTDC using PVDF/PTFE materials, is shown with brushless DC motor equipped with integrated speed control. Contact KNF application engineers for details. Models (.51) built to NSF/ANSI 169 are available. NSF flyer:
	KNF's model NF30B miniature liquid diaphragm pump is shown at left with available parallel-head connections and an economical brushless DC motor for reduced EMI/RFI and provide a long lifetime. Optional logic-controlled speed control is available with this motor. Similar in size to the model NF60, high-pressure models, single head models and a variety of motor options are available for the NF30 and NF60 series. The pumps can either be used to transfer two separate liquids simultaneously or if the heads are connected in parallel the pulsation and vibration are greatly reduced.

NOTES: Standard continuous performance ratings listed on this KNF website and on KNF datasheets are per head, and based on technical data and test results of nominal units measured at sea level, with water at 70°F (20°C) and a nominal electrical supply as listed, and are for reference only. Multiple-head models, different performance models, cost-effective OEM modifications, and a variety of motor options and different materials of construction are also available. Certified drawings are available upon request. Specifications subject to change without notice. You should always check corrosion resistance charts for compatibility with the medium you intend to pump.
