Diaphragm Dosing Pumps are chemical resistant.
June 17, 2010 -
Integrating 2-phase stepper motors, type FEM 1.02 and FEM 1.09 pumps achieve flow rates from 0.2-20 mLpm and 0.9-90 mLpm, respectively. Compact pumps measure 62 x 75 x 63 mm, cover wide dosing range (1:100), and can serve for more than 10,000 hr. Leak-tight units are self-priming to 8.5 in. Hg and demonstrate 1% repeatability. Depending on pump version, head materials include polypropylene or PVDF, while internal elastomeric components are manufactured from EPDM, FFPM, and PTFE.

KNF Diaphragm Dosing Pumps for Liquids Deliver Superior Repeatability over Long Service Life
New OEM Product in a Compact Package
New KNF diaphragm dosing pumps for liquids (Types FEM 1.02 and FEM 1.09) introduce ideal solutions delivering superior accuracy and repeatability over a long service life. These compact pumps integrate simple 2-phase stepper motors engineered for optimized levels of controllability and cost efficiency. An optional and adaptable control module easily integrated into any system can expand control potential to suit particular application requirements.
Typical applications include medical diagnostics, industrial dosing systems, fuel cells, semiconductor processing, and wafer analysis, among others.
The FEM 1.02 pump achieves flow rates from 0.2 ml/min to 20 ml/min and FEM 1.09 pump from 0.9 ml/min to 90 ml/min. Both versions are small (62mm x 75mm x 63mm), cover a wide dosing range (1:100), operate oil-free with virtually no maintenance, and can serve reliably for more than 10,000 hours.
Among other features, these pumps are self-priming to 8.5 in.Hg, demonstrate consistency over time (1% repeatability), and exhibit excellent leak-tightness and chemical resistance. An innovative valve system minimizes head volume by ensuring that air cannot collect inside the pump head. Depending on pump version, head materials include polypropylene (PP) or PVDF and internal elastomeric components are manufactured from EPDM, FFPM, and PTFE. Pumps are both easy to operate and to adjust. Ports are available in UNF ¼-28 or compression fittings.
Modular pump design offers OEMs the versatility to choose from a wide variety of standard materials, voltages, frequencies, accessories, and options to satisfy application demands.
