These compact pumps integrate simple 2-phase stepper motors engineered for optimized levels of controllability and cost efficiency.

New KNF (Trenton, NJ) 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. Features include:

• Flow rates from 0.2 ml/min to 20 ml/min (FEM1.02) and 0.9 ml/min to 90 ml/min (FEM 1.09)
• A small compact construction of 62 x 75 x 63 mm.
• Cover a wide 1:100 dosing range.
• Oil- and maintenance-free operation.
• Self-priming to 8.5 in.Hg.
• Leak-tightness and chemical resistance. 
• Available in UNF ¼-28 or compression fittings.
