TAOMSUN KingFlowCompact precision micro-piston pump more sophisticated, more compact, more flexible working principle: the use of a piston structure, the replacement mechanism through the seal cavity volume to achieve accurate trace of air or liquid operations: lessons, transfer and dispensing liquids. Accuracy guarantee: double super wear-resistant materials sealing technology and high-precision stepper motor to ensure the precision and long life operation under liquid trace. Flexible customization include: Volume fluid path interfaces, the sealing material, a position sensor, including the rotary position encoder parameter function or interface can be customized or optional. Performance parameters:? There are two flat screw holes, used as a liquid line interface M6 threaded holes and 1/4 "-28UNF two specifications Electrical Interface:? Position sensor located at the initial position of the suction NPN output type?
