APP-20KG Chemically inert piezo pump 15ml/min flow

Materials in contact with fluid: PEEK and Perfluoroelastomer (FFKM)

APP-20KG Piezo pump
APP-20KG Piezo pump port connections


Piezo pump with 15ml/min as maximum flow rate in highly inert design using PEEK and perfluoroelastomer (FFKM) as only wetted materials. 

With highly inert wetted materials such as PEEK and Perfluoroelastomer (FFKM), this small, thin and lightweight piezo pump opens up new possibilities for pumping aggressive media. With the optional double piezo stack, improved values can be achieved in the area of suction and output pressure as well as flow rate.
