DIAPHRAGM LIQUID PUMP DATA SHEET NF 2.35 NF 2.35

Transcription

1 DIAPHRAGM LIQUID PUMP DATA SHEET NF 2.35 NF 2.35 NF 2.35 DCB-A Concept KNF diaphragm liquid pumps are based on the principle of the oscillating displacement pump which is remarkably simple in design. The circular power from the motor is convert ed into vertical movement by an eccentric. This motion is then transferred to a diaphragm by means of a connecting rod which, in conjunction with an inlet and outlet valve, creates a pumping action. The NF 2.35 liquid pump can be mounted in any position. It delivers up to 350 ml/min and will operate against pressures of up to 16 bar. Features Small and powerful Micro design and maximum performance resulting from built-in technology are the outstanding characteristics of these products. Self-priming Sophisticated diaphragm technology and precise valve structures enable performances of 3 mwg suction and 16 bar pressure. Extreme chemical resistance The use of materials such as PEEK, und FFPM for the parts which come in contact with the liquid allows many neutral or corrosive liquids to be pumped. Dry running, durable and maintenance free The carefully considered design of these pumps allows them to be run dry and ensures safe operation and a long life even under the most severe conditions. Areas of use The versatility of KNF pumps allows a wide field of applications to be covered. Over many years our pumps have proved themselves in the following areas: Analysers Medicine Pharmaceutical Fuel cells Reforming Laboratory Filtration Chromatography Cleaning industry Washer/cuvette cleaning Sterilisers Industrial washing machines Printing Ink jet printing Other applications for micro-diaphragm liquid pumps include: hydrogen generators, CD coating, dental technology, textiles and many more.

2 The KNF Modular Concept of Selection General note This Data Sheet provides an overview of the options with our NF 2.35 pumps. Certain standard options will be explained in more detail where necessary. Flow curves The flow curves illustrate how the flow rate changes in relation to the pressures before and after the pump. In the case of a combination of both we would be very happy to advise what the expected flow rate would be. The values given in the curves are dependant upon the liquid, choice of head materials and the type of hoses being used. Therefore a cert ain deviation is to be expected. Note: The flow rate is measured with water at 20 C. Modules Our versatile self-selection program allows you to personally determine the optimum characteristics that you require from your pump. Select your diaphragm pump from the following characteristics: Pump type Basic model NF 2.35 Components Materials of head components 1 Materials of head components KNF offers a wide range of different materials for those parts which come in contact with the liquid thus allowing the possibility of pumping most liquids. XP Head Valves O-Rings Diaphragm Resonating diaphragm PEEK PTFE 2 Motors DCB-A Compact brushless direct current motor The brushless motors are electronically commutated and thus do not suffer from brush wear. This allows us to achieve long lifetimes similar to AC motors. Option for external motor speed control using PWM or a 0-5 V DC signal. On project request other motors are available.
